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



Ring die pellet mill has big volume and also high ability. It appropriates for factory usage and also massive production. Apartment die pellet mill is little as well as mobile. It has lower ability, ideal for house usage and also small production. The price of flat die pellet mill is much less than ring die pellet mill



Framework of flat die pellet mill.

From top to bottom, a flat die pellet mill is composed of a feed hopper, a top cupboard, a discharge electrical outlet, a pin box, gear box, a transmission shaft, an electric control closet, an electrical motor, a engine base, and also 4 wheels, and so on.



The electrical motor can be replaced by a diesel motor, gasoline engine, or a PTO connector.



The core components: 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 upper cabinet. 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 made of superior alloy steel, whose solidity is 55-60 HRC.



There are several openings on the flat die, whose diameter is from 2.5 mm to 10mm, as well as 6mm, 8mm and also 10mm are the most typical kinds. They recognize the most effective compression ratio with a large number of experiments, suitable for more than 30 type of products.



The clearance between the roller as well as flat die is 0.1-0.3 mm. This is where the raw material layer types. There are 2 changing nuts on the side of the pellet mill, you can adjust the clearance to adjust to various materials.



Just how does a flat die pellet machine work?

When you feed raw materials into the pellet machine via 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 electric motor runs and also bring along the main shaft via the gearbox. Journalism roller is mounted on the major shaft, so it revolves around the major shaft. At the same time, the rollers turn around the roller shaft.



The rotating press forms strong pressure as well as press the raw products into the holes on the flat die. The raw materials get formed in these holes. When they are ejected, they become strong cylinders. On the other hand, the solid rubbing in between roller and die warm up the raw materials to over 80 ° C, where the lignin as well as fibers get soft. They boost the glue pressure of materials.




The diameter of the pellets is established by the opening size of the flat die, while the size is identified by the slicer under the flat die. When the biomass pellets come out in the shape of cyndrical tubes, the slicer under the flat die cut them into certain length. You can readjust the placement 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 force, the pellets are sent though the discharge outlet.



2 sorts of flat die pellet machine

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



Roller-turned kind embraces a lot more effective structure. It has bigger ability and more resilient gearbox. But Die-turned kind is a lot more small and also portable, with lower cost. Naturally, both of them have the ability to make top quality pellets.



Benefits and also weakness of flat die pellet machine

Flat die pellet mill has straightforward structure. It is tiny, light and portable. The price is much less than ring die pellet machine It is very easy to operate and maintain. You can observe the pelletizing process and also solve any kind of fault in time. So it is popular with farmers, house users, and small gas manufacturing plant.



The flat dies are using parts, you require to change it consistently. But it can be used with both sides. You can transform it over when one side has actually broken. helpful site can expand their functioning life and also reduce price.



On the other hand, the relocating range are various in the inner and external side of roller, which create the slide of rollers and also abrasion on the flat die. Presently, several flat die pellet equipment embrace tapered roller to solve this problem. TICO flat die pellet machine embraces conical roller and also 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 production ability and forming rate is lower.



Just how does a ring die pellet equipment 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 equipment is driven by a direct-connected motor. The electric motor connect with the gearbox via a shaft coupling. The gearbox bring along the main shaft, and 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 with the receptacle, they are transmitted to the conditioner, where the raw materials are blended with vapor or butter. The conditioning of the raw products aims to improve the glue force as well as creating rate.



Then, the processed basic materials will certainly be transferred to the pelletizing cupboard. Under the centrifugal force, they are dispersed on the inner side of the ring die. The roller press the raw materials into the holes on the ring die. Full Article and also high pressure cause physical and chemical adjustments to the raw materials.



When they are ejected from the ring die, they come to be strong round sticks. The sticks expand longer, until they are reduced by the slicer outside the ring die. Then the pellets fall down and also come out through the outlet.



Two types of ring die pellet machine

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



In the straight type, the ring die is put up and down. When basic materials fall down from the conditioner, they are fed right into the ring die flat by a forced feeder. In the upright kind, the ring die is positioned flat. The feed hopper is right above the ring die, and also the raw materials falls into the ring die directly.



In the upright ring die pellet machine, both the roller and also ring die revolve. They develop centrifugal force as well as distribute raw materials consistently. In the horizontal ring die pellet equipment, only the ring die rotates. The raw products are distributed 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. When it comes to flat die pellet machine, the capacity is from 100kg/h to 1t/t. So if you manufacturing need is under 800kg, you would certainly better select flat die pellet machine, or ring die pellet equipment is better.



Because of the high manufacturing, the power usage each is low. The abrasion in between roller as well as die is smaller. The procedure as well as maintenance is simple. The pellets are uniform in dimension.
