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




Ring die pellet mill has big quantity and also high capability. It is suitable for manufacturing facility use and massive manufacturing. Flat die pellet mill is tiny and also portable. It has reduced capability, appropriate for residence use and small-scale production. The price of flat die pellet mill is a lot lower than ring die pellet mill



Structure of flat die pellet mill.

Inside out, a flat die pellet mill is made up of a feed receptacle, an upper cupboard, a discharge electrical outlet, a spindle box, gear box, a transmission shaft, an electrical control cupboard, an electrical motor, a engine base, and also 4 wheels, etc.



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



The core parts: roller and also 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 upper cupboard. 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 from premium alloy steel, whose solidity is 55-60 HRC.



There are many holes on the flat die, whose size is from 2.5 mm to 10mm, and also 6mm, 8mm and 10mm are the most typical kinds. They realize the most effective compression proportion with a multitude of experiments, ideal for more than 30 type of materials.



The clearance between the roller and 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 change the clearance to adapt to various materials.



Exactly how does a flat die pellet machine work?

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



When you begin the pellet equipment, the electrical motor runs and also bring along the main shaft with the gearbox. Journalism roller is mounted on the primary shaft, so it revolves around the primary shaft. At the same time, the rollers turn around the roller shaft.



The revolving press kinds solid pressure and also press the raw materials right into the holes on the flat die. The raw materials get formed in these openings. When they are ejected, they become strong cylinders. Meanwhile, the solid friction between roller and die heat up the raw materials to over 80 ° C, where the lignin and fibers obtain soft. They enhance the glue force of products.



The size of the pellets is identified by the opening dimension of the flat die, while the size is determined by the slicer under the flat die. When the biomass pellets appear in the shape of cyndrical tubes, the slicer under the flat die reduced them right into certain size. You can readjust the position of slicer to transform the size.



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



Two types of flat die pellet machine

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



Roller-turned kind adopts a lot more efficient structure. It has bigger capacity and also even more sturdy gearbox. Yet Die-turned type is much more little as well as mobile, with lower cost. Naturally, both of them are able to make premium pellets.



Advantages and also weakness of flat die pellet equipment

Flat die pellet mill has basic framework. It is tiny, light as well as mobile. The expense is a lot lower than ring die pellet equipment It is simple to operate as well as preserve. You can observe the pelletizing procedure and also fix any mistake in time. So fish feed pelleting machine price is popular with farmers, home customers, and also tiny gas production plant.



The flat dies are putting on components, you need to change it consistently. But it can be utilized with both sides. You can turn it over when one side has actually broken. In richi pellet can extend their working life and also reduce expense.



On the other hand, the relocating range are various in the inner as well as outer side of roller, which trigger the slide of rollers and also abrasion on the flat die. Presently, lots of flat die pellet machine adopt conical roller to solve this trouble. TICO flat die pellet machine embraces conical roller as well as exceptional alloy steel in the flat die.

Besides, the get in touch with location of roller as well as flat die is smaller sized than ring die pellet machine, so the manufacturing capacity as well as creating price is lower.



How does a ring die pellet machine job?

Framework of ring die pellet machine

A ring die pellet machine is composed of a screw feeder, conditioner, roller as well as ring die, discharge port, electrical motor, gearbox, pedestal.



The ring die pellet machine is driven by a direct-connected electric motor. The motor get in touch with the transmission via a shaft combining. The gearbox bring along the primary shaft, and the main 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 equipment with the receptacle, they are transferred to the conditioner, where the raw products are mixed with vapor or butter. The conditioning of the raw materials intends to boost the glue pressure as well as developing rate.



Then, the refined basic materials will be sent 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 high temperature and high pressure cause physical and chemical changes to the raw materials.



When they are ejected from the ring die, they become strong round sticks. The sticks expand longer, until they are cut by the slicer outside the ring die. Then the pellets fall down and come out via the electrical outlet.



2 types of ring die pellet machine

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



In the straight kind, the ring die is placed vertically. When basic materials drop from the conditioner, they are fed into the ring die horizontally by a forced feeder. In the upright kind, the ring die is positioned flat. The feed hopper is right over the ring die, and the raw materials falls into the ring die directly.



In the vertical ring die pellet equipment, both the roller and ring die rotate. They create centrifugal pressure as well as disperse resources consistently. In the straight ring die pellet equipment, only the ring die rotates. The raw products are dispersed in the ring die by the screw feeder.



Benefits and also weakness of ring die pellet equipment.

Ring die pellet mill features high capacity. The manufacturing per hour 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 would certainly much better select flat die pellet equipment, or ring die pellet machine is preferable.




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