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



Ring die pellet mill has huge volume and high capability. It is suitable for factory usage as well as large-scale manufacturing. Flat die pellet mill is tiny and mobile. It has reduced capability, ideal for home use and small-scale production. The rate of flat die pellet mill is much less than ring die pellet mill



Structure of flat die pellet mill.

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



The electric motor can be changed by a diesel engine, gasoline engine, or a PTO port.



The core parts: roller as well as flat die

The pelletizing part of the flat die pellet machine is a press roller and also a flat die. They are mounted 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 constructed from premium alloy steel, whose hardness is 55-60 HRC.



There are many openings on the flat die, whose diameter is from 2.5 mm to 10mm, and 6mm, 8mm as well as 10mm are one of the most common types. They recognize the best compression proportion with a great deal of experiments, ideal for more than 30 kinds of materials.



The clearance between the roller and flat die is 0.1-0.3 mm. This 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 adapt to different products.



Exactly how does a flat die pellet machine job?

When you feed resources right into the pellet machine with the hopper, they fall on the flat die as well as spread over it under the feature of roller.



When you start the pellet equipment, the electric motor runs and bring along the main shaft with the gearbox. The press roller is mounted on the main shaft, so it turns around the major shaft. Meanwhile, cattle feed pellet machine price turn around the roller shaft.



The turning press types strong stress as well as press the raw products into the holes on the flat die. The raw products get formed in these holes. When they are ejected, they end up being solid cyndrical tubes. On feed pellet machine price , the solid rubbing between roller and die heat up the raw products to over 80 ° C, where the lignin and fibers obtain soft. They enhance the sticky pressure of materials.



The diameter of the pellets is figured out by the opening dimension of the flat die, while the length is established 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 reduced them into particular length. You can readjust the position of slicer to transform the length.



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



Two sorts of flat die pellet equipment


Flat die pellet mill can be classified right into roller-turned kind as well as die-turned type. The previous one has its flat die set up on the main shaft. When the equipment functions, the flat die revolves as well as the roller maintain still. The later one has journalism roller installed on the main shaft. The roller revolves with the primary shaft, while the flat die maintain still.



Roller-turned kind embraces a lot more reliable structure. It has bigger capacity and also even more resilient gearbox. But Die-turned type is a lot more small and portable, with reduced cost. Of course, both of them have the ability to make high-quality pellets.



Advantages and weakness of flat die pellet machine

Apartment die pellet mill has simple structure. It is tiny, light and also portable. The expense is much lower than ring die pellet machine It is simple to run as well as keep. You can observe the pelletizing procedure and address any type of fault in time. So it is preferred with farmers, house individuals, as well as small gas manufacturing plant.



The flat dies are putting on components, you require to change it frequently. However it can be made use of with both sides. You can turn it over when one side has actually worn. This way you can expand their working life as well as lower price.



On the other hand, the relocating range are various in the internal as well as outer side of roller, which cause the slide of rollers as well as abrasion on the flat die. Presently, many flat die pellet machine embrace conical roller to address this problem. TICO flat die pellet machine adopts conical roller as well as exceptional alloy steel in the flat die.

Besides, the contact location of roller as well as flat die is smaller than ring die pellet equipment, so the manufacturing capability and creating price is lower.



Just how does a ring die pellet equipment job?

Structure of ring die pellet machine

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



The ring die pellet machine is driven by a direct-connected electric motor. The motor get in touch with the transmission through a shaft combining. The transmission bring along the major shaft, and the main shaft bring along the rollers. So the roller started to turn inside the ring die.



When you feed raw materials into the ring die pellet equipment via the hopper, they are transmitted to the conditioner, where the raw products are blended with vapor or butter. The conditioning of the raw products aims to enhance the sticky force as well as forming price.



Then, the refined basic materials will certainly be transferred to the pelletizing closet. Under the centrifugal force, they are distributed on the inner side of the ring die. The roller press the raw materials into the holes on the ring die. The high temperature as well as high pressure reason physical and chemical modifications to the raw products.



When they are squeezed out 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 drop and appear with the outlet.



Two kinds of ring die pellet equipment

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



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



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



Advantages and also weak point of ring die pellet machine.

Ring die pellet mill features high capability. 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 requirement is under 800kg, you would certainly better select flat die pellet equipment, or ring die pellet equipment is more suitable.



As a result of the high production, the power consumption each is reduced. The abrasion in between roller and die is smaller sized. The operation as well as maintenance is very easy. The pellets are uniform in size.
