How does a wood pellet machine job?<br>
Normally, wood pellet machine can be classified into flat die pellet machine and also ring die pellet equipment.



Ring die pellet mill has huge quantity as well as high capability. It is suitable for factory use and large production. Flat die pellet mill is tiny as well as portable. It has reduced capability, suitable for residence usage and small production. The rate of flat die pellet mill is a lot less than ring die pellet mill



Structure of flat die pellet mill.

Inside out, a flat die pellet mill is made up of a feed hopper, an upper cupboard, a discharge outlet, a pin 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 changed by a diesel motor, fuel engine, or a PTO connector.



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 installed in the upper closet. 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 made of superior alloy steel, whose hardness 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 as well as 10mm are one of the most usual kinds. They realize the most effective compression proportion with a multitude of experiments, suitable for greater 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 kinds. There are 2 changing nuts on the side of the pellet mill, you can change the clearance to adjust to different products.



Just how does a flat die pellet equipment job?

When you feed resources into the pellet equipment with the receptacle, they fall on the flat die as well as spread over it under the function of roller.



When you start the pellet machine, the electric motor runs and bring along the main shaft with the gearbox. Journalism roller is installed on the primary shaft, so it revolves around the major shaft. Meanwhile, the rollers revolve around the roller shaft.



The revolving press types solid stress and press the raw products into the holes on the flat die. The raw products get built in these openings. When they are ejected, they end up being strong cyndrical tubes. Meanwhile, the solid friction in between roller as well as die warm up the raw materials to over 80 ° C, where the lignin and also fibers obtain soft. They raise the glue force of materials.



The size of the pellets is identified by the hole size of the flat die, while the size 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 right into specific length. You can change the setting of slicer to alter 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 though the discharge electrical outlet.



Two kinds of flat die pellet machine

Flat die pellet mill can be classified into roller-turned kind as well as die-turned kind. The former one has its flat die set up on the major shaft. When the equipment functions, the flat die turns as well as the roller keep still. The later one has journalism roller mounted on the main shaft. The roller revolves with the major shaft, while the flat die maintain still.



Roller-turned type adopts much more reliable structure. It has bigger capacity and also more resilient transmission. But Die-turned kind is a lot more small and mobile, with reduced price. Obviously, both of them are able to make top quality pellets.



Advantages as well as weak point of flat die pellet machine

Apartment die pellet mill has basic structure. It is little, light and also mobile. The expense is much lower than ring die pellet machine It is very easy to run and keep. You can observe the pelletizing process as well as resolve any mistake in time. So it is prominent with farmers, house customers, as well as small gas production plant.



The flat dies are putting on components, you require to replace it frequently. Yet it can be made use of with both sides. You can transform it over when one side has broken. This way you can expand their working life and reduce expense.



On the other hand, the moving range are different in the inner and outer side of roller, which cause the slide of rollers and abrasion on the flat die. Presently, many flat die pellet machine adopt conical roller to resolve this problem. wood pellet machine maker embraces tapered roller and remarkable alloy steel in the flat die. manure pellet machine listed below to obtain a quick quote!



Besides, the call location of roller and flat die is smaller than ring die pellet equipment, so the production ability as well as creating rate is lower.



Just how does a ring die pellet machine work?

Structure of ring die pellet machine

A ring die pellet equipment is composed of a screw feeder, conditioner, roller as well as ring die, discharge port, electrical motor, transmission, stand.



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



When you feed raw materials into the ring die pellet equipment through the receptacle, they are transferred to the conditioner, where the raw products are combined with vapor or butter. The conditioning of the raw products aims to enhance the sticky pressure and also developing price.



After that, the refined resources will certainly be transferred to the pelletizing closet. Under https://uamaracaibo.org/biomass-pellet-machine/ , they are dispersed on the inner side of the ring die. The roller press the raw products into the holes on the ring die. The heat as well as high pressure cause physical and chemical changes to the raw products.



When they are squeezed out from the ring die, they end up being solid cylindrical sticks. The sticks grow much longer, up until they are cut by the slicer outside the ring die. Then the pellets fall down as well as come out through the outlet.



Two sorts of ring die pellet equipment

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



In the horizontal kind, the ring die is placed up and down. When basic materials 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 positioned flat. The feed receptacle is right above the ring die, and the raw products falls into the ring die directly.




In the upright ring die pellet machine, both the roller as well as ring die turn. They form centrifugal pressure and distribute basic materials uniformly. 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 and weak point of ring die pellet equipment.

Ring die pellet mill features high capability. The production per hour 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 production need is under 800kg, you 'd much better select flat die pellet machine, or ring die pellet machine is preferable.



Because of the high production, the power usage per unit is reduced. The abrasion between roller as well as die is smaller sized. The operation and also upkeep is simple. The pellets are consistent in dimension.
