How does a wood pellet equipment job?<br>
Typically, wood pellet equipment can be classified into flat die pellet machine and also ring die pellet equipment.



Ring die pellet mill has large volume and also high capability. It appropriates for factory usage and large production. Apartment die pellet mill is small and also portable. It has lower capability, ideal for home usage and small manufacturing. The rate of flat die pellet mill is a lot less than ring die pellet mill



Structure of flat die pellet mill.

Inside out, a flat die pellet mill is made up of a feed hopper, a top cabinet, a discharge electrical outlet, a pin box, gear box, a transmission shaft, an electric control cupboard, an electrical motor, a engine base, as well as 4 wheels, etc.



The electric motor can be changed by a diesel engine, gas engine, or a PTO connector.



The core parts: roller and also flat die

The pelletizing part of the flat die pellet machine is a press roller and a flat die. They are installed in the top cupboard. There are 2-4 rollers set up on the 2 ends of the roller shaft. The rollers have grooves on the surface area. The roller and flat die is constructed from exceptional alloy steel, whose hardness is 55-60 HRC.



There are several openings on the flat die, whose size is from 2.5 mm to 10mm, and also 6mm, 8mm as well as 10mm are one of the most typical kinds. They recognize the very best compression ratio with a lot of experiments, suitable for greater than 30 type of materials.



The clearance in between the roller and also flat die is 0.1-0.3 mm. This is where the raw material layer types. There are 2 adjusting nuts on the side of the pellet mill, you can readjust the clearance to adapt to different materials.



How does a flat die pellet equipment job?

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



When you start the pellet machine, the electrical motor runs and also bring along the primary shaft via the gearbox. The press roller is installed on the primary shaft, so it revolves around the primary shaft. At click to find out more , the rollers rotate around the roller shaft.



The turning press kinds solid stress and also press the raw materials right into the holes on the flat die. The raw materials get formed in these holes. When they are ejected, they become solid cyndrical tubes. Meanwhile, the solid friction in between roller as well as die heat up the raw materials to over 80 ° C, where the lignin and fibers get soft. They raise the glue force of materials.



The diameter of the pellets is established by the hole 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 shape of cylinders, the slicer under the flat die cut them into certain size. You can adjust the position of slicer to change the size.



After being cut by the slicers, the pellets fall down on the pellet-throwing tray. Under the feature of centrifugal force, the pellets are sent out though the discharge outlet.



Two types of flat die pellet equipment

Flat die pellet mill can be classified right into roller-turned type as well as die-turned type. The previous one has its flat die mounted on the primary shaft. When the equipment works, the flat die rotates as well as the roller maintain still. The later one has the press roller mounted on the main shaft. The roller revolves with the primary shaft, while the flat die maintain still.



Roller-turned type embraces more efficient structure. It has larger capability as well as even more sturdy gearbox. However Die-turned kind is much more small as well as portable, with lower price. Certainly, both of them have the ability to make high-grade pellets.



Benefits and also weakness of flat die pellet machine

Apartment die pellet mill has basic framework. It is little, light as well as mobile. The expense is a lot lower than ring die pellet equipment It is very easy to run as well as preserve. You can observe the pelletizing process and address any type of fault in time. So it is popular with farmers, residence individuals, as well as little gas production plant.



The flat dies are using components, you need to change it routinely. Yet it can be utilized with both sides. You can transform it over when one side has actually worn. This way you can expand their working life as well as minimize price.




On the other hand, the moving distance are different in the internal and also outer side of roller, which trigger the slide of rollers and abrasion on the flat die. Currently, lots of flat die pellet machine adopt tapered roller to solve this problem. TICO flat die pellet machine adopts conical roller and also superior alloy steel in the flat die.

Besides, the call area of roller as well as flat die is smaller than ring die pellet machine, so the manufacturing capability and also developing price is lower.



How does a ring die pellet equipment work?

Structure of ring die pellet equipment

A ring die pellet equipment is composed of a screw feeder, conditioner, roller as well as ring die, release port, electrical motor, transmission, pedestal.



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



When you feed raw materials into the ring die pellet machine via the hopper, they are transferred 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 price.



Then, the refined raw materials will certainly be transferred to the pelletizing cupboard. Under the centrifugal force, they are distributed on the internal side of the ring die. The roller press the raw materials into the holes on the ring die. The heat as well as high pressure cause physical as well as chemical changes to the raw products.



When they are ejected from the ring die, they become solid round sticks. The sticks grow much longer, till they are reduced by the slicer outside the ring die. Then the pellets drop and come out through the electrical outlet.



Two sorts of ring die pellet equipment

According to various placements of the ring die, there are vertical ring die pellet equipment and also horizontal ring die pellet machine.



In the straight kind, the ring die is positioned vertically. When raw materials fall down from the conditioner, they are fed into the ring die horizontally by a forced feeder. In the vertical type, the ring die is put horizontally. The feed hopper is right above the ring die, and also the raw materials comes under the ring die directly.



In the vertical ring die pellet equipment, both the roller as well as ring die revolve. They form centrifugal force and disperse raw materials consistently. In the straight ring die pellet machine, only the ring die rotates. The raw products are dispersed in the ring die by the screw feeder.



Benefits and weak point of ring die pellet equipment.

Ring die pellet mill features high ability. The production per hr is from 800kg to 20t. When it comes to flat die pellet equipment, the capability is from 100kg/h to 1t/t. So if you manufacturing demand is under 800kg, you 'd better select flat die pellet equipment, or ring die pellet machine is more suitable.



Due to the high production, the power intake each is low. grain pellet machine for sale between roller as well as die is smaller sized. The operation and upkeep is simple. richi pellet machine are consistent in dimension.
