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



Ring die pellet mill has large quantity and also high capacity. It appropriates for factory use and large production. Apartment die pellet mill is small and also portable. Look At This has reduced ability, appropriate for residence usage and also small manufacturing. The price of flat die pellet mill is a lot 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 receptacle, a top closet, a discharge outlet, a spindle box, transmission, a transmission shaft, an electric control cupboard, an electric motor, a engine base, as well as 4 wheels, and so on.



The electric motor can be replaced by a diesel motor, fuel engine, or a PTO port.



The core parts: roller and flat die

The pelletizing part of the flat die pellet machine is a press roller and a flat die. They are mounted in the upper closet. There are 2-4 rollers mounted on the 2 ends of the roller shaft. The rollers have grooves on the surface. The roller and flat die is made of premium alloy steel, whose firmness is 55-60 HRC.



There are several openings on the flat die, whose size is from 2.5 mm to 10mm, and 6mm, 8mm and 10mm are one of the most common types. They realize the best compression ratio with a great deal of experiments, appropriate for greater than 30 sort of materials.



The clearance between the roller and also 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 readjust the clearance to adapt to different materials.



Exactly how does a flat die pellet machine job?

When you feed resources into the pellet equipment through the receptacle, they fall on the flat die as well as spread 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 through the gearbox. Journalism roller is mounted on the main shaft, so it revolves around the major shaft. At the same time, the rollers rotate around the roller shaft.



The turning press forms strong pressure and also press the raw products right into the holes on the flat die. The raw products obtain molded in these openings. When they are squeezed out, they come to be strong cylinders. Meanwhile, the strong rubbing in between roller as well as die heat up the raw materials to over 80 ° C, where the lignin and fibers obtain soft. They boost the glue pressure of materials.



The size of the pellets is identified by the hole size of the flat die, while the length is figured out 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 right into particular length. You can readjust the position of slicer to change the length.



After being reduced 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 equipment

Apartment die pellet mill can be classified into roller-turned type and also die-turned kind. The previous one has its flat die set up on the major shaft. When the equipment functions, the flat die revolves 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 maintain still.



Roller-turned type takes on more reliable framework. It has bigger capability as well as more durable gearbox. But Die-turned type is extra tiny and mobile, with reduced cost. Obviously, both of them have the ability to make premium pellets.



Benefits and also weakness of flat die pellet machine

Apartment die pellet mill has basic framework. It is little, light and also portable. The cost is much lower than ring die pellet equipment It is simple to operate as well as maintain. You can observe the pelletizing procedure as well as solve any mistake in time. So it is preferred with farmers, house users, as well as little fuel manufacturing plant.



The flat dies are wearing parts, you need to change it on a regular basis. But it can be used with both sides. special info can transform it over when one side has actually broken. This way you can expand their working life as well as reduce expense.



On the other hand, the moving range are various in the internal and also outer side of roller, which create the slide of rollers and abrasion on the flat die. Currently, numerous flat die pellet machine adopt conical roller to solve this issue. TICO flat die pellet machine takes on conical roller as well as exceptional alloy steel in the flat die.

Besides, the get in touch with area of roller as well as flat die is smaller than ring die pellet machine, so the production capability as well as developing price is lower.



Just how does a ring die pellet machine work?

Structure of ring die pellet equipment

A ring die pellet machine is made up of a screw feeder, conditioner, roller and also ring die, release port, electric motor, gearbox, stand.



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



When you feed basic materials into the ring die pellet equipment with the receptacle, they are transferred to the conditioner, where the raw materials are combined with vapor or butter. The conditioning of the raw materials intends to boost the glue force as well as developing rate.



Then, the processed resources will be sent to the pelletizing closet. Under the centrifugal pressure, they are distributed on the internal side of the ring die. The roller press the raw products into the holes on the ring die. The heat and high pressure reason physical as well as chemical adjustments to the raw products.



When they are ejected from the ring die, they become solid cylindrical sticks. The sticks expand longer, till they are cut by the slicer outside the ring die. After that the pellets fall down as well as come out via the outlet.



Two sorts of ring die pellet machine

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




In the horizontal kind, the ring die is positioned vertically. When raw materials drop from the conditioner, they are fed right into the ring die flat by a forced feeder. In the upright type, the ring die is placed horizontally. The feed hopper is right above the ring die, as well as the raw materials comes under the ring die straight.



In the upright ring die pellet machine, both the roller and also ring die turn. They develop centrifugal force and also distribute resources uniformly. In the horizontal ring die pellet machine, just the ring die rotates. The raw materials are dispersed in the ring die by the screw feeder.



Benefits and weak point of ring die pellet equipment.

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



As a result of the high production, the power intake per unit is reduced. The abrasion between roller and also die is smaller sized. The operation as well as maintenance is very easy. The pellets are consistent in size.
