How does a wood pellet machine work?<br>
Normally, wood pellet equipment can be classified right into flat die pellet equipment and ring die pellet equipment.



Ring die pellet mill has big volume and also high capability. It appropriates for manufacturing facility usage and also massive manufacturing. Flat die pellet mill is little as well as portable. It has reduced capability, ideal for home use as well as small production. The cost of flat die pellet mill is a lot less than ring die pellet mill



Structure of flat die pellet mill.

From top to bottom, a flat die pellet mill is composed of a feed receptacle, an upper cabinet, a discharge outlet, a spindle box, gear box, a transmission shaft, an electrical control closet, an electrical motor, a engine base, and 4 wheels, and so on.



The electrical motor can be changed by a diesel engine, gas engine, or a PTO port.



The core components: roller and flat die

The pelletizing part of the flat die pellet machine is a press roller and a flat die. They are set up in the top closet. There are 2-4 rollers set up on the 2 ends of the roller shaft. The rollers have grooves on the surface. The roller as well as flat die is made of remarkable alloy steel, whose solidity is 55-60 HRC.



There are numerous openings on the flat die, whose diameter is from 2.5 mm to 10mm, and 6mm, 8mm and 10mm are one of the most common kinds. They realize the very best compression ratio with a multitude of experiments, ideal for greater than 30 type of materials.




The clearance between the roller as well as flat die is 0.1-0.3 mm. richi pellet machine is where the raw material layer forms. There are 2 adjusting nuts on the side of the pellet mill, you can adjust the clearance to adjust to different materials.



Just how does a flat die pellet equipment job?

When you feed raw materials into the pellet machine through the receptacle, they fall on the flat die as well as spread over it under the function of roller.



When you begin the pellet machine, the electric motor runs and also bring along the primary shaft with the transmission. The press roller is installed on the major shaft, so it revolves around the main shaft. On the other hand, the rollers rotate around the roller shaft.



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



The diameter of the pellets is determined by the hole dimension of the flat die, while the size is identified by the slicer under the flat die. When the biomass pellets appear in the form of cyndrical tubes, the slicer under the flat die reduced them right into specific size. You can adjust the placement of slicer to transform 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 sorts of flat die pellet machine

Apartment die pellet mill can be classified right into roller-turned type and also die-turned type. The former one has its flat die set up on the major shaft. When the machine works, the flat die revolves and also the roller maintain still. The later one has the press roller set up on the primary shaft. The roller revolves with the major shaft, while the flat die maintain still.



Roller-turned kind embraces a lot more efficient structure. It has bigger capacity and also even more sturdy transmission. But Die-turned kind is a lot more little as well as portable, with lower expense. Naturally, both of them have the ability to make top notch pellets.



Benefits and weakness of flat die pellet equipment

Apartment die pellet mill has straightforward framework. It is little, light as well as portable. The cost is much less than ring die pellet equipment It is simple to run and also maintain. You can observe the pelletizing procedure and also resolve any kind of fault in time. So it is preferred with farmers, residence customers, and little fuel manufacturing plant.



The flat dies are using components, you require to change it regularly. However it can be made use of with both sides. You can turn it over when one side has worn out. By doing this you can expand their functioning life and lower price.



On the other hand, the relocating range are various in the inner as well as external side of roller, which create the slide of rollers and abrasion on the flat die. Presently, numerous flat die pellet equipment embrace tapered roller to address this issue. TICO flat die pellet machine takes on tapered roller and exceptional alloy steel in the flat die.

Besides, the contact location of roller as well as flat die is smaller sized than ring die pellet machine, so the manufacturing ability and also forming rate is reduced.



Exactly how does a ring die pellet equipment job?

Framework of ring die pellet machine

A ring die pellet machine is made up of a screw feeder, conditioner, roller and also ring die, release port, electric motor, transmission, pedestal.



The ring die pellet machine is driven by a direct-connected motor. The electric motor connect with the transmission with a shaft combining. The transmission bring along the main shaft, and the major shaft bring along the rollers. So the roller began to rotate inside the ring die.




When you feed raw materials right into the ring die pellet machine through the receptacle, they are transferred to the conditioner, where the raw products are mixed with vapor or butter. The conditioning of the raw products intends to enhance the adhesive force and also creating price.



Then, the refined resources will be transferred to the pelletizing cabinet. Under the centrifugal pressure, they are distributed on the inner side of the ring die. The roller press the raw materials right into the holes on the ring die. The high temperature and high pressure cause physical and chemical adjustments to the raw materials.



When they are ejected from the ring die, they become solid round sticks. The sticks expand longer, until they are cut by the slicer outside the ring die. After that the pellets fall down as well as come out via the electrical outlet.



2 types of ring die pellet machine

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



In the straight type, the ring die is put up and down. When raw materials fall down from the conditioner, they are fed into the ring die horizontally by a forced feeder. In the upright type, the ring die is placed flat. The feed hopper is right over the ring die, and the raw products falls into the ring die directly.



In the vertical ring die pellet machine, both the roller and ring die turn. They develop centrifugal force and distribute raw materials evenly. In the horizontal ring die pellet machine, just the ring die rotates. The raw materials are dispersed in the ring die by the screw feeder.



Benefits as well as weak point of ring die pellet machine.

Ring die pellet mill features high capacity. The manufacturing per hour is from 800kg to 20t. As for flat die pellet equipment, the capability is from 100kg/h to 1t/t. So if you manufacturing requirement is under 800kg, you 'd much better pick flat die pellet machine , or ring die pellet machine is better.



Because of the high production, the power consumption each is reduced. The abrasion between roller as well as die is smaller sized. The operation and also upkeep is easy. The pellets are consistent in dimension.
