Exactly how does a wood pellet equipment work?<br>
Generally, wood pellet machine can be classified into flat die pellet machine as well as ring die pellet equipment.



Ring die pellet mill has large quantity and high capability. It is suitable for factory use and also large production. Apartment die pellet mill is tiny as well as mobile. It has lower capacity, appropriate for house use as well as small production. The rate of flat die pellet mill is a lot lower than ring die pellet mill



Framework of flat die pellet mill.

Inside out, a flat die pellet mill is made up of a feed receptacle, an upper closet, a discharge outlet, a pin box, gear box, a transmission shaft, an electrical control cupboard, an electric motor, a engine base, and also 4 wheels, and so on.



The electric motor can be replaced by a diesel engine, fuel engine, or a PTO adapter.



The core parts: roller and also flat die

The pelletizing part of the flat die pellet equipment is a press roller and also a flat die. They are mounted in the upper closet. There are 2-4 rollers mounted on the 2 ends of the roller shaft. The rollers have grooves on the surface area. The roller as well as flat die is constructed from remarkable alloy steel, whose solidity is 55-60 HRC.



There are several openings on the flat die, whose size is from 2.5 mm to 10mm, and 6mm, 8mm and 10mm are one of the most typical types. They recognize the best compression ratio with a lot of experiments, ideal for more than 30 type of products.



The clearance between the roller and also flat die is 0.1-0.3 mm. pellet mill for feed is where the raw material layer types. There are 2 changing nuts on the side of the pellet mill, you can change the clearance to adjust to different products.



Just how does a flat die pellet machine work?

When you feed basic materials right into the pellet equipment via the hopper, they fall on the flat die and spread over it under the feature of roller.



When you start the pellet machine, the electrical motor runs and bring along the main shaft through the gearbox. Journalism roller is installed on the major shaft, so it turns around the primary shaft. At the same time, the rollers rotate around the roller shaft.



The turning press kinds solid pressure and also press the raw products right into the holes on the flat die. The raw products get formed in these openings. When they are squeezed out, they become strong cyndrical tubes. On the other hand, the solid friction between roller and die warm up the raw products to over 80 ° C, where the lignin and also fibers obtain soft. They boost the adhesive pressure of materials.



The size of the pellets is figured out by the opening size of the flat die, while the size is established by the slicer under the flat die. When the biomass pellets come out in the form of cylinders, the slicer under the flat die cut them right into certain length. You can adjust the position of slicer to change the length.



After being reduced by the slicers, the pellets fall down on the pellet-throwing tray. Under the function of centrifugal pressure, the pellets are sent out though the discharge electrical outlet.



Two types of flat die pellet equipment

Apartment die pellet mill can be classified into roller-turned kind and also die-turned kind. The former one has its flat die set up on the major shaft. When the equipment functions, the flat die rotates and the roller maintain still. The later one has journalism roller installed on the main shaft. The roller revolves with the main shaft, while the flat die maintain still.



Roller-turned kind embraces more efficient structure. It has bigger ability and more long lasting transmission. But Die-turned kind is extra tiny and mobile, with lower price. Of course, both of them have the ability to make high-grade pellets.



Advantages as well as weakness of flat die pellet machine

Apartment die pellet mill has straightforward framework. It is little, light and also mobile. The price is much less than ring die pellet equipment It is easy to run and keep. You can observe the pelletizing process and also solve any kind of mistake in time. So it is prominent with farmers, residence users, and tiny gas manufacturing plant.



The flat dies are putting on parts, you require to change it regularly. Yet it can be used with both sides. You can turn it over when one side has broken. By doing this you can expand their working life and reduce expense.



On the other hand, the moving range are various in the internal and also external side of roller, which create the slide of rollers and abrasion on the flat die. Currently, several flat die pellet machine adopt tapered roller to address this issue. TICO flat die pellet machine embraces conical roller and also superior alloy steel in the flat die.

Besides, the contact area of roller and also flat die is smaller than ring die pellet equipment, so the manufacturing capacity and creating price is reduced.



How does a ring die pellet machine work?

Framework of ring die pellet equipment

A ring die pellet machine is composed of a screw feeder, conditioner, roller and also ring die, discharge port, electric motor, transmission, stand.



The ring die pellet equipment is driven by a direct-connected electric motor. The electric motor connect with the transmission via a shaft coupling. The transmission bring along the primary shaft, and also the primary shaft bring along the rollers. So the roller began to turn inside the ring die.



When you feed raw materials right into the ring die pellet machine with the receptacle, they are transmitted to the conditioner, where the raw materials are combined with vapor or butter. The conditioning of the raw products intends to enhance the adhesive pressure and also developing rate.




Then, the refined raw materials will be transferred to the pelletizing closet. Under the centrifugal pressure, they are dispersed on the internal side of the ring die. alfalfa pellet mill press the raw products right into the holes on the ring die. The high temperature and high pressure cause physical and chemical modifications to the raw products.



When they are squeezed out from the ring die, they end up being solid round sticks. The sticks expand much longer, up until they are cut by the slicer outside the ring die. After that the pellets fall down and also appear with the electrical outlet.



2 sorts of ring die pellet equipment

According to different positionings of the ring die, there are vertical ring die pellet equipment as well as horizontal ring die pellet equipment.



In the straight type, the ring die is put vertically. When basic materials drop from the conditioner, they are fed right into the ring die horizontally by a forced feeder. In the vertical type, the ring die is positioned flat. small scale wood pellet production is right over the ring die, and also the raw products falls under the ring die directly.



In the vertical ring die pellet machine, both the roller as well as ring die rotate. They develop centrifugal force as well as disperse basic materials uniformly. In the straight ring die pellet equipment, only the ring die rotates. The raw materials are dispersed in the ring die by the screw feeder.



Benefits and weak point of ring die pellet machine.

Ring die pellet mill includes high ability. The production per hr is from 800kg to 20t. As for flat die pellet equipment, the capacity is from 100kg/h to 1t/t. So if you manufacturing need is under 800kg, you 'd much better select flat die pellet machine, or ring die pellet machine is better.



Because of the high production, the power intake each is reduced. The abrasion in between roller and die is smaller. The procedure as well as upkeep is easy. The pellets are consistent in size.
