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



Ring die pellet mill has huge volume and also high capability. It is suitable for manufacturing facility usage and large manufacturing. Apartment die pellet mill is small and portable. It has lower ability, ideal for residence use and small manufacturing. The cost of flat die pellet mill is much lower than ring die pellet mill



Structure of flat die pellet mill.

Inside out, a flat die pellet mill is composed of a feed hopper, an upper closet, a discharge outlet, a spindle box, transmission, a transmission shaft, an electric control cabinet, an electric motor, a engine base, as well as 4 wheels, and so on.



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 equipment is a press roller and a flat die. They are mounted 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 area. The roller and flat die is constructed from exceptional alloy steel, whose solidity is 55-60 HRC.



There are several holes on the flat die, whose diameter is from 2.5 mm to 10mm, and also 6mm, 8mm and 10mm are one of the most typical types. They understand the best compression proportion with a lot of experiments, ideal for more than 30 kinds of products.



The clearance between the roller and also 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 change the clearance to adapt to different products.



How does a flat die pellet equipment work?

When you feed basic materials into the pellet machine via the hopper, they fall on the flat die as well as sp read over it under the feature of roller.



When you begin the pellet machine, the electrical motor runs as well as bring along the major shaft via the gearbox. The press roller is installed on the major shaft, so it revolves around the major shaft. At the same time, the rollers rotate around the roller shaft.



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



The size of the pellets is identified by the hole size of the flat die, while the length is determined by the slicer under the flat die. When the biomass pellets come out in the shape of cylinders, the slicer under the flat die cut them into certain length. 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 force, the pellets are sent though the discharge outlet.



2 types of flat die pellet machine

Apartment 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 major shaft. When the machine works, the flat die rotates and also the roller keep still. The later one has the press roller set up on the major shaft. The roller revolves with the main shaft, while the flat die keep still.



Roller-turned type takes on more effective framework. It has larger capacity and also more durable transmission. Yet Die-turned kind is a lot more tiny and also mobile, with lower cost. Of course, both of them are able to make high-quality pellets.



Advantages and also weakness of flat die pellet machine

Apartment die pellet mill has straightforward framework. It is small, light and mobile. machine for making chicken feed is a lot less than ring die pellet machine It is easy to run as well as preserve. You can observe the pelletizing process as well as fix any kind of mistake in time. So it is prominent with farmers, home individuals, and tiny gas manufacturing plant.



The flat dies are using components, you require to change it consistently. Yet it can be utilized with both sides. You can transform it over when one side has broken. By doing this you can prolong their functioning life as well as minimize price.



On the other hand, the moving range are various in the internal and external side of roller, which trigger the slide of rollers and also abrasion on the flat die. Presently, several flat die pellet machine embrace conical roller to solve this trouble. TICO flat die pellet equipment takes on tapered roller and premium alloy steel in the flat die.

Besides, the contact area of roller and also flat die is smaller sized than ring die pellet machine, so the manufacturing ability and also creating price is reduced.



Just how does a ring die pellet machine work?

Structure of ring die pellet machine

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



The ring die pellet machine is driven by a direct-connected motor. The motor get in touch with the transmission via a shaft combining. The gearbox bring along the major shaft, and also the major shaft bring along the rollers. So the roller began to rotate inside the ring die.



When you feed resources right into the ring die pellet equipment via the hopper, they are transmitted to the conditioner, where the raw materials are blended with vapor or butter. The conditioning of the raw products intends to boost the glue force as well as creating price.



Then, the processed raw materials will be transmitted 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 also high pressure cause physical as well as chemical changes to the raw products.



When they are squeezed out from the ring die, they come to be solid round sticks. The sticks grow longer, until they are reduced by the slicer outside the ring die. After that the pellets fall down and also come out through the outlet.



Two types of ring die pellet equipment

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




In the horizontal type, the ring die is placed up and down. When resources 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 horizontally. The feed hopper is right above the ring die, and the raw materials falls under the ring die directly.



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



Benefits and also weak point of ring die pellet equipment.

Ring die pellet mill features high capability. The manufacturing per hour is from 800kg to 20t. When it comes to flat die pellet equipment, the ability is from 100kg/h to 1t/t. So if you production need is under 800kg, you 'd much better pick flat die pellet equipment, or ring die pellet machine is preferable.



Because of the high production, the power usage per unit is low. The abrasion between roller and also die is smaller. The procedure and also upkeep is very easy. The pellets are uniform in size.
