Yes, this is a very common challenge we address. High-moisture pig manure is not suitable for direct pelleting in any ring die pellet mill. At Richi Machinery, we don’t just sell a machine; we provide a complete process solution. For high-moisture materials, we always recommend a pretreatment stage that includes solid-liquid separation (using a screw press) followed by efficient mixing with dry auxiliary materials like crushed straw, sawdust, or previously recycled fine pellets.

This mixture is then conditioned to achieve the ideal moisture content (typically between 15-25%) and fiber structure for successful pelleting. Our engineers will design this pretreatment system to ensure your pig manure is perfectly prepared for our manure pellet machine, preventing die clogging and ensuring stable, high-yield production.

Absolutely. Combining cow manure with waste grass is an excellent way to create a balanced organic fertilizer, but it does require specific equipment adjustments. The grass adds significant fiber, which increases the material’s elasticity and requires greater compressive force to form durable pellets.

For such mixtures, our Richi manure granulator would be configured with a ring die that has a higher compression ratio. This forces the fibrous material through longer, narrower die holes under greater pressure, ensuring the particles bond tightly together to form a hard, low-dust pellet. During the project design phase, we analyze your specific material ratios to recommend the perfect ring die specification for your operation.

We understand that not every operation is large-scale, which is why Richi Machinery offers a range of manure pelletizers to suit different budgets and production goals. Our MZLH series, for example, includes models perfectly suited for outputs starting from 1 ton per hour.

These models retain the core principles of our larger machines—such as robust gearbox transmission and high-quality ring dies—but in a more compact and cost-effective package. We can provide a simplified production line that focuses on the essential steps: fermentation, crushing, pelleting, and screening, significantly reducing your initial investment while still delivering a high-quality, commercial-grade pellet.

You have identified the key challenge with sheep manure pelleting. Its low lignin content and high fibrous nature make it less prone to natural binding. A “standard” pelletizer will indeed struggle. This is where our expertise in custom ring die design becomes critical.

For sheep manure, we recommend and supply a ring die with several specific features: a thicker die profile to increase material retention time under pressure, smaller hole diameters to create more resistance, and a specially engineered “release bore” profile that encourages the formed pellet to be cleanly cut off. This custom design, combined with potential process adjustments like adding a small percentage of a binder, allows our manure compost machine to successfully transform difficult sheep manure into premium pellets.

This is an excellent question that highlights the need for customized solutions. There is no single “perfect” ratio, as it depends on the initial moisture and fiber content of both your duck manure and mushroom residue. However, as a general starting point from our project experience, a mixture in the range of 60% fermented duck manure to 40% mushroom residue often provides a good balance. The mushroom residue acts as a superb dry bulking agent and fiber source, absorbing excess moisture from the manure and providing structure. The final optimal ratio is determined through lab analysis and small-scale trials at our facility. We can guide you through this testing process to define the precise formula that will work best in your manure pellet mill for a high-hardness, low-breakage product.

For large-scale operations like yours, equipment durability is not just a feature—it’s a necessity for profitability. Our high-capacity manure pellet machines, such as the FZLH series, are engineered specifically for continuous, 24/7 production environments. The ring dies and rollers are manufactured from premium alloy steels (e.g., 40CrNiMo) and undergo a deep carburizing and hardening process, achieving a surface hardness of HRC 56-60.

This gives them exceptional wear resistance. Under normal operating conditions and with proper maintenance, our customers typically achieve a lifespan of 2,000 to 3,000 production hours for these core components before reconditioning is needed. We also ensure quick availability of these wear parts to minimize your downtime.

This material can be used, but not “directly” without some form of conditioning. The loose, bulky nature of used stable bedding means it has a very low bulk density, which would lead to very low production capacity and poor pellet quality in a manure pelletizer. The key is proper pretreatment. The material must first be composted to stabilize it and break down some of the more resilient fibers.

After composting, it often needs to be shredded or crushed to achieve a uniform particle size. In many cases, it may also need further drying. Once processed to the correct moisture and particle size, this mixture pellets very well. Our engineers can design the necessary pretreatment line to transform your stable bedding into an ideal feedstock for pelleting, turning a waste product into a valuable commodity.

Yes, producing high-quality, polished pellets from valuable materials like quail manure is a specialty of our equipment. The smooth appearance and low powder content are achieved through precise control of the pelleting conditions in our manure making machine. We achieve this by using a ring die with a highly polished, smooth hole surface finish and the exact compression ratio for your material’s recipe.

This ensures the material flows smoothly through the die without tearing. Furthermore, our machines are equipped with adjustable cutters, allowing you to cleanly cut the pellets to a uniform length without creating fines. The result is a premium, dust-free pellet that maximizes the market value of your quail manure fertilizer.

Feathers are a known challenge in poultry manure processing. To address this, our manure processing machine line includes several protective measures. First, we recommend installing a powerful, standalone magnetic separator and a specific “tramp iron trap” in the feeding conveyor before the material reaches the pellet mill. More critically, the feed inlet to our pellet mill is designed to prevent bridging and wrapping.

For severe feather contamination, we can equip the feeder with a rotating “picker” mechanism that actively pulls feathers and long fibers into the pressing chamber without allowing them to entangle. Inside the chamber, the severe shear forces between the roller and die often shred the feathers, incorporating them into the pellet. A comprehensive solution starts with proper system design to protect the machine.

This is a fundamental question for any fertilizer producer. While both can form granules, they are suited for different end goals. A tooth agitator granulator (or “new-type organic granulator”) works on a agglomeration principle, tumbling moist material to form soft, irregular balls. It is less sensitive to moisture and fiber but produces lower-density pellets that are prone to breaking down and are not ideal for long-distance transport or commercial sale.

In contrast, a ring die manure pellet mill uses extreme pressure to force material through a hardened steel die, creating dense, cylindrical pellets with a polished appearance. This process results in granules with high mechanical strength, low moisture content, and excellent storage and transport properties—essential for a commercial fertilizer product. For anyone serious about producing a high-value, marketable pellet from manure, the ring die pelletizer is the unequivocally superior and industry-standard choice. The tooth agitator is a low-cost option for on-farm, non-commercial use.

We offer varying levels of automation to match your investment and labor strategy. A fully automated manure pellet production line from Richi Machinery is absolutely achievable. This would involve PLC-controlled systems that link the feed rate of the mixer, the operation of the manure pellet mill (with automatic lubrication and load control), the cooler, the screener, and the packaging machine.

In such a setup, the primary role of the operators (typically 2-3 per shift) shifts from manual labor to monitoring the control panel, managing the raw material infeed, and handling packaged pallets. For smaller operations, we provide semi-automated lines where key processes are linked by conveyors but may require more manual intervention. We design the line to fit your operational philosophy.

Yes, the final pellet diameter is determined solely by the hole size in the ring die. To change the particle size, you must replace the entire ring die with one that has the desired aperture (e.g., from 4mm to 6mm). The process of changing a die is a standard maintenance operation.

With proper tools and training, our machines are designed for efficient die replacement. For an experienced operator, the entire process—from shutting down the machine, removing the old die, installing the new one, and reassembling—typically takes between 1 to 2 hours. We provide detailed manuals and video guides to ensure your team can perform this task confidently.

A operating manure pelletizer generates noise from the mechanical drive and the pelleting process itself, typically in the range of 85-95 dB(A). It also creates dust, primarily at the discharge point where hot pellets are cut. Therefore, we always recommend implementing basic environmental controls in your workshop.

This includes providing hearing protection for operators and installing a local exhaust hood above the pellet mill outlet connected to a simple bag-filter dust collection system. For the cooler and screener, we offer integrated cyclone or bag-house dust collectors. We consider these not as optional extras, but as integral components of a professional and responsible manure processing plant, and we include them in our plant layout designs.

Definitely. This is a key strategic advantage of investing in a Richi ring die pellet mill from the start. Our manure pellet machines are designed to be highly versatile. The process of pelleting organic-inorganic blends is fundamentally the same; the machine simply applies high pressure to compact the mixed powder.

The inclusion of mineral fertilizers like N, P, and K may require us to supply a ring die with a different, more corrosion-resistant material (such as stainless steel) to handle the salt content, but the core machine itself remains perfectly suitable. This future-proofs your investment and allows you to diversify your product line as market demands shift.

As a turnkey project supplier, Richi Machinery’s core competency is the seamless integration of all equipment. We do not simply source individual machines; we design the entire system. This means the crusher’s output particle size is matched to the requirements of the pellet mill, the dryer’s capacity and temperature profile are calculated to prepare the material perfectly, and all components are connected with correctly sized conveyors and control systems.

This ensures smooth material flow and stable operation. Regarding energy consumption, for a complete line with a 1 ton/hour output, the total connected power is typically between 90-120 kW. For a 3 ton/hour line, it can range from 250-350 kW. The actual energy use depends on the specific raw material characteristics, but we provide detailed power calculations during the project proposal phase.

Our technical training is comprehensive and hands-on. It typically covers: safe operation procedures, daily maintenance routines, troubleshooting common issues (like uneven feeding or low pellet hardness), and step-by-step guidance on critical tasks like ring die and roller replacement.

We conduct this training during the installation and commissioning phase at your site. For after-sales support, we have a 24/7 remote assistance program. Our engineers can connect via video call to help diagnose issues. Furthermore, we maintain a large stock of fast-moving spare parts (rollers, dies, shear pins, bearings) to ensure we can dispatch them to you within days, not weeks, minimizing your production downtime.

The following will introduce the production process of manure organic fertilizer production line:

1. Raw material preparation

The raw materials of granular organic fertilizer mainly include animal and plant residues, agricultural waste, feces and other organic matter. During the production process, these raw materials need to be processed and processed.

First, the raw materials are crushed to make their particle size uniform; then, the crushed raw materials are composted, adding an appropriate amount of water and fermentation agent to promote the decomposition and transformation of organic matter; finally, the composted raw materials are screened and removed. Impurities, remove impurities and substances that are not conducive to particle formation.

2. Fermentation treatment

Composted raw materials need to be fermented. First, the raw materials are piled to form a certain compost volume. Then, by controlling the temperature, humidity, ventilation and other conditions of the compost pile, the decomposition and fermentation of organic matter are promoted.

During the fermentation process, the pile needs to be turned regularly to increase the supply of oxygen and accelerate the decomposition of organic matter and the fermentation rate. Through fermentation treatment, the organic matter in the raw materials is converted into stable organic fertilizer.

3. Granulation treatment

The organic matter after fermentation needs to be granulated. The purpose of granulation processing is to form organic materials into granules for easy storage, transportation and application. Granulation is usually carried out using a manure pellet mill.

• First, the fermented organic matter is ground to make its pellets uniform in size;
• then, the ground organic matter is mixed with a binder to increase the stability of the pellets;
• finally, the mixture is pressed and shaped through a manure pellet mill, forming pellet manure organic fertilizer.

4. Drying treatment

The granulated organic fertilizer needs to be dried. The purpose of drying treatment is to reduce the moisture content of the pellets and improve the stability and storage of the pellets. Usually a dryer is used for drying. The granulated organic fertilizer is put into the manure dryer, and the water inside the granules is evaporated by the action of hot air, so that the granules reach a certain moisture content. Dried organic fertilizer can be stored for a long time and is not easy to deteriorate.

5. Packaging and storage

The dried pellet organic fertilizer needs to be packaged and stored. It is usually packaged in sealed packaging materials such as plastic bags to prevent moisture and air from entering. Packaged organic fertilizers should be stored in a cool, dry, and ventilated warehouse away from direct sunlight and rain. At the same time, attention should be paid to moisture-proofing to prevent organic fertilizers from deteriorating and failing.

The production process of organic fertilizer pellets includes steps such as raw material preparation, fermentation treatment, granulation treatment, drying treatment, packaging and storage.

By controlling these steps scientifically and rationally, granular bio-organic fertilizers with stable quality and rich nutrition can be produced to provide effective nutritional supplements for agricultural production.

The so-called manure pellet mill equipment selection is to select the best solution from a variety of different models and specifications of equipment that can meet the same needs and make a purchase decision through technical and economic analysis and evaluation. Reasonable selection of equipment can maximize economic benefits from limited funds.

The principles that should be followed when selecting compost granulating machine are as follows:

• The first thing to consider is its suitability for production. Only equipment that is suitable for production can achieve its investment effect;
• The second is technological advancement. Technical advancement must be based on production suitability and aim to obtain maximum economic benefits;
• Finally, unify production applicability, technological advancement and economic rationality.

Generally speaking, technological advancement and economic rationality are unified. Because technologically advanced equipment not only has high production efficiency, but also produces high-quality products.

01 Selection of main parameters of the equipment

① Productivity

The productivity of manure pellet mill equipment is generally expressed by the product output of the equipment per unit time (minutes, hours, shifts, years).

Equipment productivity must be compatible with the company’s business policy, factory planning, production plan, transportation capacity, technical strength, labor force, power and raw material supply.

You cannot blindly demand that the higher the productivity, the better. Otherwise, the production will be unbalanced and not only will not be able to give full play to the effect is to cause losses.

② Craftsmanship

The most basic thing about manure pellet mill is that they must meet the technical requirements of the fertilizer process. The ability of the organic fertilizer granulator machine to meet the requirements of the production process is called processability.

In addition to the basic requirements, the requirements for equipment operation and control are also very important. Generally, the manure pellet mill is required to be light in operation and flexible in control.

02 Equipment reliability and maintainability

① Equipment reliability is a prerequisite for maintaining and improving equipment productivity.

People who invest in equipment hope that the equipment can work without failure in order to achieve the expected purpose. This is the concept of equipment reliability. Reliability lies largely in equipment design and manufacturing. Therefore, the design and manufacturing quality of the equipment must be considered when selecting manure pellet mill equipment.

When selecting equipment reliability, it is required to make the mean failure interval of its main components as long as possible. Specifically, the safety factor, redundancy design, environmental design, component stability design, safety design and human resources can be selected from the equipment design. Analyze machine factors and other aspects.

With the continuous updating of products, the reliability requirements of equipment are also constantly increasing. Equipment designers and manufacturers should provide reliability indicators of product design to facilitate users to select manure pellet mill equipment.

② Maintainability of equipment

People always hope that the manure pellet mill equipment they invest in can be easily repaired once it breaks down, that is, the equipment has good maintainability. When selecting equipment, the maintainability of the equipment can be measured from the following aspects:

• The technical drawings and information of the equipment are complete. It is convenient for maintenance personnel to understand the structure of the equipment and is easy to disassemble and inspect.
• The structural design should be reasonable. The overall layout of the equipment structure should comply with the principle of accessibility. Each component and structure should be easily accessible for inspection and maintenance.
• Structure simplicity. On the premise of meeting the usage requirements, the structure of the equipment should be as simple as possible. The fewer parts that need to be repaired, the better. It should be easier to disassemble and quickly replace wearing parts.
• Principles of standardization and combination. The manure pellet mill equipment uses standard parts and components as much as possible, can be easily disassembled into several independent parts, devices and components, and can be assembled into a complete machine without special means.
• Advanced structure. The equipment should be designed using the principles of automatic adjustment, automatic wear compensation and preventive measures as much as possible.
• Condition monitoring and fault diagnosis capabilities. Instruments, meters, sensors and supporting instruments on the manure pellet mill equipment can be used to monitor the temperature, pressure, voltage, current, vibration frequency, power consumption, efficiency, automatic detection of finished products and equipment output parameter dynamics of relevant parts of the equipment to judge the technology of the organic manure making machine.
• Provide special tools and instruments, appropriate spare parts, or have convenient supply channels.

03 Equipment safety and operability

① The safety of equipment is the performance of the manure pellet mill equipment in ensuring production safety, that is, the equipment should have the necessary safety protection design and devices to avoid human and machine accidents and economic losses.

During equipment selection, if you encounter newly put into use safety protection components, you must ask them to provide experimental and usage reports and other information.

② The operability of manure pellet mill equipment belongs to the category of ergonomics. The general requirements are convenience, reliability, safety, and compliance with ergonomic principles. The main matters that usually need to be considered are as follows:

• The operating mechanism and its location comply with the requirements of labor protection regulations and are suitable for operators of average size.
• Fully consider the physiological limits of the operator, and do not allow the operator to withstand ultra-high physical limits of operating force, activity rhythm, movement speed, endurance, etc. within the legal operating time.
• The design of the equipment and its operating room must meet the requirements that are conducive to reducing the mental fatigue of workers.

04 Environmental protection and energy saving of equipment

The environmental protection of equipment usually refers to the degree of impact of its noise, vibration and harmful substance emissions on the surrounding environment. When selecting equipment, it must be required that its noise, vibration frequency and harmful substance emissions are controlled within the scope of national and regional standards. .

When selecting, no matter what type of enterprise, the manure pellet mill equipment purchased must comply with various standards and requirements stipulated in the “Energy Law” of the country where it is located.

05 Economy of equipment

The main economic factors that should be considered when selecting equipment include:

• Initial investment;
• Adaptability to the product;
• Production efficiency;
• Durability;
• Energy and raw material consumption;
• Maintenance and repair costs, etc.

The initial investment of manure pellet mill equipment mainly refers to purchase fees, transportation and insurance fees, installation fees, auxiliary facilities fees, training fees, customs fees, etc.

When purchasing manure pellet mill equipment, you cannot simply seek cheap prices and reduce the evaluation criteria of other influencing factors. In particular, you must fully consider the costs of downtime losses, maintenance, spare parts and energy consumption, as well as various management fees.

In short, the economic efficiency of equipment is measured based on the equipment life cycle cost, and the highest economic benefit of equipment investment is pursued on the basis of reasonable life cycle cost.

The purchase of manure pellet mills is directly related to the production efficiency and product quality of the organic fertilizer production line. Therefore, it is particularly important to choose a suitable equipment manufacturer. RICHI will discuss the key factors that should be considered when choosing an organic fertilizer pellet machine manufacturer.

1. Understand the strength of the manufacturer

When choosing an equipment manufacturer, you must first understand its comprehensive strength. This includes the manufacturer’s production scale, technical level, research and development capabilities, market reputation, etc. You can comprehensively evaluate the strength of the manufacturer by visiting its production base, learning about its past project cases, and asking professionals in the industry.

2. Examine equipment performance

The performance of the equipment is directly related to the production efficiency and product quality of the manure pellet mill.

Therefore, when selecting equipment, an in-depth examination of its performance should be conducted. Including equipment stability, degree of automation, production efficiency, energy conservation and environmental protection, etc. At the same time, it is also necessary to consider whether the equipment complies with relevant national standards and regulations.

3. Consider after-sales service

The after-sales service of equipment is also an aspect that cannot be ignored when choosing a manufacturer. Excellent manufacturers should be able to provide complete after-sales services, including equipment installation and commissioning, operator training, regular maintenance, etc.

In addition, manufacturers should also be able to respond to customers’ maintenance needs in a timely manner to ensure that the fertilizer granulation equipment can operate stably during the production process.

Choosing a suitable manure pellet mill manufacturer requires comprehensive consideration of the manufacturer’s strength, equipment performance, after-sales service, price and cost-effectiveness, and innovation capabilities.

Only through comprehensive evaluation and careful comparison can you find the equipment manufacturer that best suits you and provide a strong guarantee for the long-term and stable operation of the organic fertilizer processing production line.

The so-called organic fertilizer made by manure pellet mill refers to natural fertilizer, which is widely used in agricultural production. It can improve the soil environment and allow crops to grow better. So what is the future of organic fertilizers?

01 Meet the demand for green and pollution-free food

It is of great significance to use organic fertilizers instead of traditional chemical fertilizers to provide a variety of nutrients to crops and improve the quality of agricultural products. Therefore, we should pay attention to the use of organic fertilizers, use organic fertilizers to meet people’s demand for green, pollution-free food, and make organic fertilizers more widely used in agricultural production.

02 The demand for organic fertilizers is increasing

Most countries around the world have agricultural sectors, and growing crops requires a huge amount of fertilizers. Moreover, with the rapid development of social economy, the development of organic agriculture and ecological agriculture is also gradually increasing. The market prospects for organic fertilizers are very promising.

03 Can reduce pollution

In rural areas, there are many natural fertilizers, that is, various animal feces produced by breeding enterprises, which are actually very good fertilizers. However, in the process of urbanization and the continuous large-scale development of agriculture, these organic wastes are considered It is a product of environmental pollution. Composting with organic fertilizers can mitigate the effects of these problems.

04 Improve soil environment

In recent years, soil pollution caused by traditional chemical fertilizers and excessive heavy metals in the soil have promoted the development space of my country’s organic fertilizer market. Moreover, the development of organic fertilizer industry is also one of the effective measures to prevent and control eutrophication of water bodies in my country.

05 Organic fertilizer has high nutritional content

Organic fertilizers made by manure pellet mill contain many types of nutrients, which can not only provide nutrients for crops, but also enhance their disease resistance, drought resistance, and waterlogging tolerance; they can increase production, improve crop quality, and improve food safety.

In the future, it is believed that organic fertilizers will slowly replace traditional fertilizers and be widely used in agricultural production. This shows that the market development potential of organic fertilizers is huge. (Find RICHI on YouTube)
