Just how does a wood pellet machine job?<br>
Normally, wood pellet machine can be classified right into flat die pellet equipment as well as ring die pellet machine.



Ring die pellet mill has huge quantity as well as high capability. It is suitable for manufacturing facility use and large-scale production. Flat die pellet mill is little and also mobile. It has lower capacity, appropriate for home usage and also small manufacturing. The price 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 composed of a feed hopper, a top closet, a discharge outlet, a spindle box, transmission, a transmission shaft, an electrical control cupboard, an electric motor, a engine base, and 4 wheels, etc.



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



The core parts: roller as well as flat die

The pelletizing part of the flat die pellet equipment is a press roller as well as a flat die. They are installed in the top cabinet. There are 2-4 rollers set up on the 2 ends of the roller shaft. The rollers have grooves on the surface. The roller and also flat die is made from premium 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 as well as 10mm are the most usual kinds. They realize the very best compression ratio with a great deal of experiments, ideal for more than 30 kinds of materials.



The clearance between the roller as well as flat die is 0.1-0.3 mm. This is where the raw product layer forms. There are 2 changing nuts on the side of the pellet mill, you can readjust the clearance to adapt to different products.



Exactly how does a flat die pellet machine job?

When you feed raw materials into the pellet equipment with the hopper, they fall on the flat die and also spread over it under the function of roller.



When you start the pellet equipment, the electrical motor runs and bring along the major shaft through the gearbox. The press roller is set up on the main shaft, so it rotates around the primary shaft. At the same time, the rollers rotate around the roller shaft.



The rotating press kinds solid stress and also press the raw products into the holes on the flat die. The raw materials obtain built in these holes. When they are ejected, they end up being solid cylinders. On the other hand, the solid friction between roller and die warm up the raw materials to over 80 ° C, where the lignin and fibers get soft. They boost the glue pressure of products.



The size of the pellets is figured out by the opening dimension of the flat die, while the length is identified by the slicer under the flat die. When the biomass pellets appear in the form of cylinders, the slicer under the flat die reduced them right into particular size. You can adjust the position of slicer to alter the length.



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



Two kinds of flat die pellet machine

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



Roller-turned kind takes on extra efficient framework. It has larger ability and also even more durable transmission. Yet Die-turned type is a lot more small and also portable, with lower price. Certainly, both of them are able to make top notch pellets.



Advantages and weak point of flat die pellet equipment

Apartment die pellet mill has basic framework. Richi machine is tiny, light and mobile. The expense is a lot less than ring die pellet equipment It is simple to run and preserve. You can observe the pelletizing process and fix any type of fault in time. So it is prominent with farmers, house customers, and also tiny gas manufacturing plant.



The flat dies are putting on parts, you require to replace it on a regular basis. But it can be made use of with both sides. You can transform it over when one side has actually worn. In this way you can prolong their working life as well as decrease expense.



On the other hand, the moving range are various in the internal and outer side of roller, which trigger the slide of rollers and abrasion on the flat die. Presently, several flat die pellet equipment take on tapered roller to resolve this issue. TICO flat die pellet equipment embraces conical roller as well as remarkable alloy steel in the flat die.

Besides, the get in touch with location of roller and also flat die is smaller sized than ring die pellet equipment, so the manufacturing ability and also developing rate is reduced.



How does a ring die pellet machine work?

Structure of ring die pellet equipment

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



The ring die pellet machine is driven by a direct-connected electric motor. The motor connect with the gearbox via a shaft coupling. The gearbox bring along the major shaft, as well as the major shaft bring along the rollers. So the roller started to revolve inside the ring die.



When you feed basic materials into the ring die pellet machine via the hopper, they are transferred to the conditioner, where the raw materials are mixed with vapor or butter. The conditioning of the raw materials intends to enhance the sticky force and also developing price.



Then, the refined raw materials will certainly be transmitted to the pelletizing closet. Under the centrifugal force, they are dispersed on the inner side of the ring die. The roller press the raw products right into the holes on the ring die. The heat and also high pressure cause physical and chemical adjustments to the raw materials.



When they are squeezed out from the ring die, they end up being solid round sticks. The sticks expand longer, up until they are reduced by the slicer outside the ring die. After that the pellets drop as well as come out via the outlet.



Two types of ring die pellet equipment

According to different placements of the ring die, there are vertical ring die pellet equipment as well as straight ring die pellet machine.



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



In the vertical ring die pellet machine, both the roller as well as ring die rotate. They develop centrifugal pressure and distribute resources evenly. In the straight ring die pellet machine, only the ring die rotates. The raw products are distributed in the ring die by the screw feeder.



Benefits and weakness of ring die pellet equipment.

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




Because of the high production, the power consumption per unit is low. check my reference in between roller and also die is smaller. The procedure and also upkeep is simple. straw pellet mill for sale are consistent in size.
