Structural composition of coal pellet making machine

The roller-type coal dust pellet machine consists of a main motor, a power transmission device, a ring die, a pressure roller, a feed hopper, a feeding screw, a sprinkling nozzle, a discharge hopper, a frame, etc.

• The power transmission device mainly includes a control cabinet, motor, gear, reducer, coupling, overload protection device and transmission shaft.
• An overload protection device is installed between the coupling and the reducer. When raw materials accumulate and foreign objects fall into the extrusion zone, the overload protection device immediately interrupts power transmission to avoid damage to the machine.
• There is a pair of pressure rollers installed in the ring die cavity, and the power is transmitted to the ring die and the pressure roller by two drive shafts with opposite directions respectively, so that the ring die and the pressure roller can move relative to each other at the same time.
• Under the combined action of shear force and friction force, materials envelop and overlap each other and enter the die hole for molding, which can improve the molding rate and molding density of the material.

Working principle of coal pellet making machine

• When working, the power of the motor is transmitted to the feeding screw, sprinkling nozzle, pressure roller and ring die through the transmission device.
• The crushed material is sent to the feeding port, and the rotating feeding screw pushes the material to the sprinkling nozzle. Under the action of the centrifugal force of the sprinkling nozzle, the material is evenly sprinkled on the inner wall of the ring die cavity. The ring die and a pair of pressure rollers rotate relative to each other.
• Under the strong extrusion force, the material is continuously forced into the straight hole of the molding.
• After pressure maintenance, During the process, the originally loose materials are bonded together and solidified into shape, and are discharged from the ring die through the pressure relief hole.
• After reaching a certain length, the material is automatically cut off and dropped into the transmission mechanism through the discharge port to be taken away, thereby completing the entire granulation process.

How to choose coal pellet making machine?

When purchasing a coal pellet making machine, you should pay attention to several aspects to avoid choosing unqualified products or purchasing a coal dust briquette machine that cannot be used normally. Frequent failures will occur in the later production process, resulting in the factory being unable to achieve profitability.

1. The model/power of the coal briquette machine is the first thing to consider.
   You should choose the appropriate wood pellet machine according to the capacity of your transformer. Generally, there is a simple calculation formula. The power of the pellet machine host multiplied by 1.44 times is the minimum required transformer capacity. For example, a pellet machine with a host power of 132 kilowatts requires at least 132×1.44=190.08, so a transformer of at least 200KVA is required to start a 132 kilowatt motor.
2. Quality of coal pellet making machine.
   We need to observe whether the core parts are produced independently, whether there is a processing workshop, and whether the accuracy of the processing equipment meets the processing needs of the hollow shaft and bearing chamber of the coal powder briquetting machine.
   We should pay attention to the motor brand, the diameter of the main shaft, and the center distance length between the input shaft and the output shaft of the gearbox to avoid purchasing poor quality and substandard equipment.
3. Versatility of coal pellet making machine accessories.
   The versatility of accessories such as pellet machine molds, pressure rollers, pressure roller eccentric shafts, etc. is also a key point. If you purchase non-standard products, you will later purchase wearing parts such as molds and pressure rollers, or you need to purchase repair parts after the charcoal powder making machine is damaged.
   At this time, if the pellet machine purchased is a non-standard product, the wearing parts and parts will be damaged. The original manufacturer has a monopoly and prices are on the high side. It is even possible that the original manufacturer will not be able to purchase the required parts after it goes bankrupt due to poor management.
4. Coal briquette machine price.
   As the saying goes, you get what you pay for. It is unrealistic to spend the least amount of money to buy the best pellet machine. You can only choose a relatively cost-effective coal briquette making machine product through on-site inspection and comparison, and the one that suits you is the best.

Coal pellet making machine price

The price of coal pellet machine is generally 10,000-100,000 USD.

Price seems to be the primary issue that many customers consider, because price is the most intuitive. However, before understanding your needs, all we can give is a range, because the factors that affect the price of the pellet machine are as follows:

Model and capacity of coal pellet making machine

Capacity and equipment model are one of the factors that affect the price of the coal dust pellet machine. The output of the pellet machine plays a decisive role in the price. Coal pellet making machines with different outputs and models have different processes, materials, and labor costs.

Therefore, the greater the output, the higher the price. The more advanced the model, the higher the price of the pellet machine. Therefore, we need to know how many tons or kilograms of pellets you want to produce per hour.

Quality of coal pellet making machine

The quality of the equipment plays a decisive role in the price of the pellet machine. For the same type of equipment, many small manufacturers sell it at low prices, which can only reduce production costs and cut corners. As industrial equipment for processing pellet output. “You get what you pay for” must be the truth.

If possible, you need to visit the coal pellet making machine manufacturer before purchasing the equipment to determine the materials of the granulator body, ring die, and pressure rollers, determine the brands of the following bearings and motors, determine the safety configuration of the granulator, and inspect the actual performance of the coal granulator.

In addition, you can also directly ask the manufacturer to provide testing services.

At RICHI, we offer standard coal pellet machines and customized coal pellet machines. The standard coal pellet maker is fully sufficient for customers to achieve efficient and long-term trouble-free operation.

However, based on our strong equipment design and manufacturing capabilities, we can customize materials, motors, electrical components, painting solutions, etc. according to the actual needs of customers. Services, some of which are value-added services, while most customization services and trial services are free.

Accessories

When purchasing a coal pellet making machine or a complete set of coal pellet production system equipment, accessories are necessary, which will also affect the final quotation of the coal briquette machine.

Most customers will choose to purchase many accessories at once. This will not only avoid the time and transportation costs of secondary purchases in a short period of time, but also avoid the failure of accessories to arrive in time when there is a problem with the equipment.

Therefore, the more accessories you purchase, the higher your final equipment quote will be. At present, many of our customers also need customized accessories. If additional costs are incurred, it will also affect the final product quotation.

The above are several factors that affect the quotation of coal pellet making machines. RICHI can only give accurate quotations for coal pellet mills and coal pellet production lines by first asking customers for their specific requirements and circumstances. Therefore, when you consult about coal pellet machines, you can describe your needs based on the following:

• What capacity per hour you want to get?
• You want to get single coal pellet mill machine or a complete coal pellet production line?
• What kind of material and expected end product are you planning to have?
• Budget for machinery purchasing?
• Points that you really focus on. (Some customers have special process requirements and require customized granulators.)

How to process coal pellets?

Coal fines are fed into a mixer with biomass raw materials. Once granule formation has begun, mixed materials are fed onto a coal pellet making machine, where they are further grown and rounded into more refined coal pellets.

From the coal pelletizer, they are fed to a cooler, where they are dried into a final product. The advantage of a pelletizing process is that pellet size and durability is more easily controlled.

In the process of making coal pellets, not only pelleting is required, but it also needs to be mixed with other biomass raw materials, crushed, and cooled. According to customer needs, a packaging process may also need to be added.
