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



Ring die pellet mill has huge volume as well as high ability. It appropriates for manufacturing facility use and massive production. Flat die pellet mill is little as well as mobile. It has lower capability, ideal for residence use as well as small production. The rate of flat die pellet mill is much lower than ring die pellet mill



Framework of flat die pellet mill.

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



The electric motor can be replaced by a diesel motor, gas engine, or a PTO adapter.



The core parts: roller as well as flat die

The pelletizing part of the flat die pellet equipment is a press roller as well as a flat die. Read Full Report are set up 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 area. The roller and flat die is constructed from exceptional alloy steel, whose firmness is 55-60 HRC.



There are many openings on the flat die, whose size is from 2.5 mm to 10mm, and also 6mm, 8mm and also 10mm are the most common types. They understand the very best compression ratio with a multitude of experiments, ideal for more than 30 sort of products.



The clearance between the roller as well as flat die is 0.1-0.3 mm. This is where the raw product layer kinds. There are 2 readjusting nuts on the side of the pellet mill, you can readjust the clearance to adapt to various products.



Exactly how does a flat die pellet machine work?

When you feed basic materials into the pellet equipment with the hopper, they fall on the flat die and spread over it under the feature of roller.



When you start the pellet equipment, the electric motor runs and also bring along the major shaft via the transmission. Journalism roller is set up on the primary shaft, so it revolves around the primary shaft. At the same time, the rollers rotate around the roller shaft.



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



The diameter of the pellets is figured out by the opening dimension 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 cyndrical tubes, the slicer under the flat die cut them right into specific size. You can change the setting of slicer to change the size.



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 electrical outlet.



2 types of flat die pellet equipment

Flat die pellet mill can be classified into roller-turned kind and also die-turned type. The former one has its flat die set up on the primary shaft. When the equipment works, the flat die revolves and also the roller maintain still. The later one has the press roller installed on the main shaft. The roller revolves with the major shaft, while the flat die keep still.



Roller-turned kind adopts a lot more effective framework. It has bigger ability and also even more resilient transmission. Yet Die-turned type is more tiny as well as mobile, with reduced price. Obviously, both of them are able to make high-quality pellets.



Advantages and also weakness of flat die pellet machine

Apartment die pellet mill has simple framework. It is tiny, light and mobile. The expense is a lot lower than ring die pellet equipment It is simple to run and also preserve. You can observe the pelletizing process and also resolve any type of fault in time. So it is popular with farmers, home users, and also little fuel production plant.



The flat dies are putting on parts, you need to change it on a regular basis. But it can be utilized with both sides. You can transform it over when one side has broken. This way you can extend their working life and also lower cost.



On the other hand, the moving range are different in the inner as well as external side of roller, which trigger the slide of rollers and also abrasion on the flat die. Currently, numerous flat die pellet machine adopt conical roller to address this issue. TICO flat die pellet machine adopts tapered roller as well as premium alloy steel in the flat die.

Besides, the contact location of roller and also flat die is smaller than ring die pellet machine, so the production capability and also developing rate is lower.



Just how does a ring die pellet machine job?

Structure of ring die pellet machine

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



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



When you feed resources into the ring die pellet equipment through the hopper, they are transferred to the conditioner, where the raw materials are blended with vapor or butter. The conditioning of the raw materials aims to boost the glue pressure as well as developing rate.



After that, the processed resources will certainly be sent to the pelletizing closet. Under the centrifugal pressure, they are dispersed on the inner side of the ring die. The roller press the raw products right into the holes on the ring die. The high temperature and high pressure reason physical as well as chemical adjustments to the raw materials.



When they are squeezed out from the ring die, they come to be strong round sticks. The sticks grow longer, till they are cut by the slicer outside the ring die. Then the pellets fall down and also appear through the electrical outlet.



Two kinds of ring die pellet equipment

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



In the horizontal type, the ring die is positioned up and down. When basic materials drop from the conditioner, they are fed right into the ring die horizontally by a forced feeder. In the upright type, 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 upright ring die pellet machine, both the roller and ring die revolve. They create centrifugal pressure and distribute resources consistently. In the horizontal ring die pellet machine, just the ring die rotates. The raw materials are distributed in the ring die by the screw feeder.




Benefits as well as weak point of ring die pellet equipment.

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



Due to the high manufacturing, the power consumption per unit is reduced. The abrasion in between roller and also die is smaller. The procedure and also upkeep is simple. The pellets are uniform in dimension.
