How to choose biomass wood pellet machine? Choose large or small wood pellet machine? In recent years, biomass pellet investment projects have become more and more popular, and wood pellet machine is an important equipment for producing biomass pellet fuel.RICHI specializes in wood pellet machine for sale, next let us give you some advice.

Many customers have considered this: first buy a small wood pellet for small production, cheap investment, and then use it, start with a small investment, and then increase the investment after making money. In fact, it is normal to have such an idea, but when choosing easily repaired, whether parts are wear-resistant, and whether they are easy to operate need to be considered.

Find a few more quipment, you need to see the following points:

(1) Preliminary Preparation

Make a good investment budget, inspect raw materials, workshops, electricity, and sales markets.

(2) Choose Equipment According To Materials

Different materials have different process and require different equipment. Energy consumption and output, maintenance costs, whether they can be easily repaired, whether parts are wear-resistant, and whether they are easy to operate need to be considered. Find a few more wood pellet machine manufacturers to explain the situation, and they will make a plan for you free of charge.

(3) Choose A Reliable Manufacturer

On-site inspection, when necessary, you can bring materials to test the machine. Regular manufacturers generally have after-sales training to learn how to use the wood pellet machine.

Facts have proved that a good operator not only has high granulation efficiency, but also knows how to maintain the electric wood pellet machine and prolong the service life.

(4) Select Larger Capacity Wood Pellet Machine

Under the same production task, the larger wood pellet machine saves labor and facilitates management. So, find a professional manufacturer who can tell you this, and specializes in wood pellet machine for sale.

For example, the scale of the wood pelleting plant with 8 wood pellet machines can save hundreds of thousands of dollars in labor costs every year. And the large-scale pellet machine saves the floor space and saves more than half of the space. It also saves maintenance and spare parts, spare parts purchase and replacement time, labor required for replacement, etc.

Generally speaking, large-scale wood pellet machines have more advanced design, better stability and performance, large motor power and torque, wide moderation, easier production, easier scale effect, and lower production costs. The overall stability of the machine is good, and the wood pellet machine cost is naturally high.

Richi Machinery not only provides a single wood pellet machine for sale, but also a complete set of wood pellet plant equipment. With the help of RICHI’s complete wood pelletizingsolutions, customers can choose within a more precise range even if they do not know the equipment, reduce energy and financial investment, and focus on controlling the project progress.

Whether it is sawdust, shavings, or wood log, tree trunks, branches, or heavy wooden pallets, our wood pellet machines for sale,  covers the entire process chain of processing all types of wood pellets.

Under the condition of high temperature (the wood pellets making machine operating temperature of the wood pellet machine, no additional heating device is required), the lignocellulose contained in the wood chips can be softened, thereby increasing the cohesive force of the lignocellulose, and under the action of external pressure, the wood Cellulose molecular clusters are dislocated, deformed, and extended, and the adjacent biological pellets inside are bonded to each other, recombined, and pressed into shape.

RICHI wood pellet machine adopts annular die and matching cylindrical pressure roller as the main working parts, which is mainly composed of feeding, stirring, transmission and lubricating systems. Because the axis of the die is usually arranged horizontally, it is often called a horizontal ring die wood pellet making machine.

The raw materials are stirred and mixed by specially configured copying plates in the batching bin, quenched and tempered, and then the screw feeder feeds the materials into the electric wooden pellet machine for granulation.

In the best wood pellets machines, the screed plate evenly distributes the quenched and tempered materials between the ring die and the pressing roller. The ring die is driven by the motor to rotate, and the two pressing rollers installed in the ring die only rotate but do not revolve under the action of the material between the die rollers and the friction between them.

Due to the rotation of the ring die and the pressing roller, the material between the die and the roller is clamped and squeezed, and finally extruded continuously from the die hole in a column shape, and then cut into a certain length of pellets with a cutter.

Note: Generally speaking, the compressed wood pellet machine does not work alone, and also needs a lot of equipment to cooperate. Therefore, a complete set of wood pelletizing plant system process mainly includes raw material drying, pulverization (dust removal), air conveying, collection, raw material mixing and stirring, screw conveying, granulation molding, cutting, cooling, packaging, storage and other processes.

Richi Machinery is not only focusing on wood pellet machine for sale, but RICHI wood pellet production line solutions have become more and more mature after nearly 30 years of operation. This type of solution includes technical assistance in the entire process of production line design, site planning, and process plan, and is tracked and responsible by the project manager, making the project progress and cost input more clear.

1. First, the wood chips are transported horizontally to the magnetic separator, the wood chips without metal are sent to the next section after a 45°turn, and the wood chips and metals with metal are turned by 135°and then sent to the impurity outlet to be removed from the wood pellet machine plant;
2. The wood chips after metal removal are sent to the next screening process by vertical wind lifting. During the vertical lifting process, due to the large proportion of sand and gravel, they cannot be transported by the lifting wind, so they will be trapped in this wood fuel pellet plant process;
3. After the wood chips are lifted, they are transported horizontally again. In this link, the wood chips need to pass through a filter screen of a certain length. The wood chips larger than the filter screen aperture cannot enter the next wood pellet machinel process and will be sent back to the chipper for reprocessing.
4. The wood chips containing metal, unqualified wood chips, sand and metal and other sundries in the raw material are all screened and removed in this section, and the qualified wood chips are sent to the coarse pulverizer by the bucket elevator and belt conveyor for pulverization.

Note: The processed wood chips are stored in the wood chip bin through screw conveyors, belt conveyors and bucket elevators. (If the raw material is logs or very thick trunks, you need to add wood splitter equipment; if it is dry sawdust and shavings, after cleaning and magnetic separation, it can be directly sent to the pellet mill for wood);

The processed wood chips usually contain impurities such as soil, sand, and metal, which will cause great wear to the pellet mill for wood; in addition, wood chips longer than 3 cm do not meet the processing requirements of the next section, so an air-selection and dry-cleaning system is added in this section, to remove impurities and screen the wood chips.

In order to further reduce energy consumption and make full use of solar energy, a transparent material preparation shed should be used to centrally store the processed wood chips, and the moisture content of the wood chips should be reduced to 20% to 25% under the conditions of natural light and ventilation. After storage and drying, the wood chips are sent to the crushing system.

1. First, the clean wood chips enter the coarse pulverization process of the pulverizing system. Generally, a hammer mill is used, which can pulverize the wood chips to wood chips with a length of 5-6 mm.
2. Then, it is directly dried in the pipeline of the channel dryer, and the heating medium of the dryer is clean high-temperature flue gas.
3. The dried wood chips are sent to the water conditioning system. The water conditioning system can control the moisture content according to the drying conditions of the wood chips. The moisture content of the wood chips from the water conditioning system is controlled at about 10%.
4. The wood chips with qualified moisture content are then ground by a fine pulverizer, and the diameter of the pulverized particles is less than 3 mm, so as to meet the requirements of the industrial wood pellet machine for processing raw materials.

Some people will look for horizontal wood pellet machine for sale online, and some people will look for vertical wood pellet machine for sale. As a professional compressed wood pellets machine manufacturer, Richi Machinery will objectively compare the two types of products for everyone.

01 Origin
The horizontal sawdust wood pellets machines originated earlier than the vertical ring die biomass wood pellet machine and is mature and stable. The horizontal ring wood pellet machine originated in 1883, and the vertical wood granulator originated in Shandong Province, China in the past ten years. Compared with the vertical wood pellet machine, the horizontal wood pellet machine has a longer service time and higher stability.

02 Applicability of raw materials
The horizontal wood pellets machine has high torque, low speed output, and wide applicability to raw materials. It can be used for raw materials such as high moisture, uneven thickness, and complex types. Vertical ring die wood pellet machines are very “picky” about raw materials.

03 Sealing
The granulation chamber of the horizontal pellet mill for wood is sealed, and all the raw material dust is isolated in the closed space of the ring die to eliminate the phenomenon of ash leakage.

The main shaft of the vertical automatic wood pellet making machine is installed vertically, and the dust raw material is in direct contact with the transmission mechanism, which increases the wear of the transmission mechanism.

04 Granulation quality
Due to the large mass of the drive wheel and the ring die, the horizontal biomass wood pellet making machine rotates around the axis and generates a large torque relative to the material. During the process, the material is formed at high speed and high pressure to achieve high-quality pellets.

Vertical biomass wood pellet making machines are directly bearing with pressure roller, light weight, small relative rotational inertia, slow pressing material speed, and the molding effect is slightly worse than horizontal type.

05 Parts replacement and material blocking maintenance
The door cover of the horizontal saw dust wood pellet machine is opened on the side, which is convenient to replace the wearing parts. The main shaft of the vertical wood pellet machine must be removed to remove the machine, which is troublesome to maintain.

When the horizontal type encounters material blockage or boring machine, it can be cleaned up by shutting down the door and opening the door cover. The vertical wood pellet machine must disassemble all the mechanisms above the ring die to clean it.

In addition, the horizontal automatic wood pellet machine has an overload protection device, which can respond quickly and protect the motor and transmission parts, while the vertical type does not.

06 Pelletizing and molding
The feeding method of the horizontal biomass sawdust wood pellet machine is equipped with a forced feeding device, which can force the material into the granulation chamber and increase the filling rate of the granulation chamber. The material is easy to shape. The vertical wood pellet machine relies on the material’s own weight to fall into the granulating chamber.

If the auxiliary materials are uneven or the thickness of the material varies greatly, the material with large mass sinks to the bottom first, and the material with light weight always floats on the top, which eventually leads to the difficulty of the material forming.

07 Service life
The high temperature in the pelletizing chamber of the sealed horizontal biomass wood pellet machine causes the ring die to frequently damage the bearings. The vertical commercial wood pellet press roller is installed vertically, due to neutral reasons, the bearings are often burned due to lack of oil.

The above is the difference between the horizontal commercial wood pellet machineand the vertical wood pellet machine. Each has its advantages and disadvantages. When choosing a wood pellet machine mill or a manufacturer who focus on wood pellet machine for sale, you should purchase the corresponding supporting equipment and determine the model and quantity of the supporting equipment.

Wood pellets refers to the use of forest tending and felling residues, as well as wood processing residues, sawdust, bark, etc. as raw materials, under high pressure (49-196MPa) and heating conditions, compressed into granular and solid moldings , its density can reach 1.1-1.5 t/m3, and its calorific value can reach more than 4500 kcal/kg. It has combustion characteristics equivalent to secondary bituminous coal, and its ash content is less than 1.5%.

Generally, the wood pellet machine mill is suitable for molding when the moisture content is 12%-15% and the size of the raw material before enter in the wood pellet machine is less than 5 mm.

01 Tree Species
The chemical composition, cellulose content and calorific value of different species of wood will affect the quality of wood pellets. Among them, the calorific value is also very different depending on the tree species and their proportions.

Different tree species have different wood fibers. The wood of tree species with fine fibers has good flexibility, good shape of sawdust, and is easy to be pelletized by wood pellet machines, such as poplar, pine, etc.; tree species with thick fiber have poor flexibility, the sawdust is broken, and pelletizing is difficult to shape.

02 Wood Density
Sawdust with low wood density has good plasticity and is easy to form.

03 Wood Moisture Content
The moisture content of wood has a great influence on the production of wood chips. With high moisture content, the wood is easy to stick in the wood pellet hammer mill , and the output decreases rapidly. The moisture content of wood chips before pelleting should be controlled between 10% and 15%, otherwise the pellets will burst due to excessive internal steam.

04 Production Equipment
Wood pellet machines are key factor affecting the quality of wood pellets, especially wood pellet machines, wood pellet hammer mill and wood dryers. Their mechanical properties have a great impact on the output of the wood pellet plant and the quality of pellets.If you are looking for wood pellet machine for sale, find Richi Machinery.

The requirements for the raw materials of the biomass wood pellet machine directly affect the quality of the wood pellets. Only by controlling the raw materials can high-quality pellets be made. So, what are the requirements for raw materials when the industrial wood pellet machine is pelletizing?

01 Material Size
When the electric wood pellet machine is granulated, the size of the raw material is required. Generally, the size of the raw material after crushing must be less than 5MM.

The specific crushing size is also determined according to the expected diameter of the pellets and the size of the diameter of the electric pellet mill die. If the raw material is crushed too large or too small, it will affect the output and quality of the pellets, and even cause no material.

02 Raw Material Moisture
When the wood pellets are granulated, there are also strict requirements for moisture. No matter what kind of raw material, the moisture must be controlled within 12-18%. If the moisture is too large or too small, the pellets will be easily broken or loose.

03 The Raw Material Completely Gets Rid Of The Sticky Agent
There is no need to add any binder when making wood pellets, because wood chips themselves are a kind of crude fiber raw material and have certain adhesiveness. Then it can be formed naturally after being squeezed by the wood pellet machine.

Don’t be afraid if you encounter raw materials without adhesiveness, RICHI ring die wood pellet making machines can help you. This biomass wood pellet machine can produce strong pressure due to its special structure, and it is the nemesis of difficult-to-form raw materials. The resulting pellets are dense and smooth.

04 Different Raw Materials Can Be Mixed For Pellet Mills Granulation
The pellet mill for wood is not only able to use one kind of sawdust for pelleting, but also can be mixed with other kinds of sawdust. In general, it can also be mixed with crop straw, fruit shell, peanut shell, straw and so on.

The pellets made by mixing other varieties of sawdust are still high-quality pellets, and the pellets mixed with straw, because the quality of the straw itself is not as good as that of the sawdust, the quality of the pellets will be slightly lower, and at this time, it cannot be called wood pellets but straw pellets.

05 Do Not Be Afraid Of Mildew Of Raw Materials
Sometimes there are more raw materials collected, and if they are not used up for a while, the raw materials will be mildewed and blackened. At this time, the pressed pellets cannot reach the required density and heat, and it is a pity to throw them away.

There is no need to worry about the mildew of the raw materials, as long as we add more than 50% of the fresh raw materials, the more new raw materials are added, the higher the quality of the pellets will be. The specific situation depends on the customer’s needs.

Richi Machinery always adheres to customer-centricity, using new technology to make products from every tiny component to the whole wood pellet plant machine, have a strong technical guarantee and build core competitiveness!
