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



Ring die pellet mill has large volume as well as high ability. It is suitable for factory use and massive production. cattle feed pellet mill is small and mobile. It has reduced capability, appropriate for home use as well as 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, an upper closet, a discharge electrical outlet, a spindle box, transmission, a transmission shaft, an electric control closet, an electric motor, a engine base, and also 4 wheels, etc.



The electric motor can be changed by a diesel engine, fuel engine, or a PTO connector.



The core parts: roller and also flat die

The pelletizing part of the flat die pellet equipment is a press roller and also a flat die. They are set up 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. The roller as well as flat die is made of premium alloy steel, whose solidity is 55-60 HRC.



There are numerous openings on the flat die, whose diameter is from 2.5 mm to 10mm, and 6mm, 8mm and also 10mm are the most typical kinds. They understand the best compression proportion with a lot of experiments, suitable for greater than 30 kinds of materials.



The clearance between the roller and also flat die is 0.1-0.3 mm. This is where the raw material layer forms. There are 2 adjusting 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 job?

When you feed basic materials right into the pellet equipment with the hopper, 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 also bring along the main shaft through the gearbox. The press roller is set up on the major shaft, so it rotates around the primary shaft. On the other hand, the rollers revolve around the roller shaft.



The revolving press types strong pressure and press the raw products into the holes on the flat die. The raw materials obtain formed in these openings. When they are ejected, they become strong cylinders. At the same time, the solid friction in between roller and die heat up the raw products to over 80 ° C, where the lignin as well as fibers obtain soft. They raise the adhesive force of materials.



The diameter of the pellets is determined by the opening dimension of the flat die, while the length is identified by the slicer under the flat die. When the biomass pellets come out in the form of cylinders, the slicer under the flat die reduced them into certain size. You can change the setting of slicer to alter the size.



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




2 sorts of flat die pellet machine

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



Roller-turned type embraces much more effective framework. machine a pellet has larger ability as well as more resilient transmission. But Die-turned kind is extra small and portable, with lower price. Obviously, both of them have the ability to make high-quality pellets.



Advantages and also weakness of flat die pellet equipment

Apartment die pellet mill has easy structure. It is little, light and also portable. The expense is much less than ring die pellet machine It is very easy to operate and maintain. You can observe the pelletizing procedure and also fix any kind of mistake in time. So it is prominent with farmers, residence individuals, as well as small gas manufacturing plant.



The flat dies are wearing parts, you require to replace it consistently. But it can be made use of with both sides. You can transform it over when one side has worn out. By doing this you can expand their functioning life as well as minimize expense.



On the other hand, the moving distance are different in the internal and external side of roller, which create the slide of rollers as well as abrasion on the flat die. Currently, lots of flat die pellet machine take on tapered roller to address this problem. TICO flat die pellet equipment takes on conical roller and also exceptional alloy steel in the flat die.

Besides, the call location of roller and also flat die is smaller than ring die pellet machine, so the production ability as well as developing price is lower.



Exactly how does a ring die pellet equipment job?

Framework of ring die pellet machine


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



The ring die pellet machine is driven by a direct-connected motor. The electric motor connect with the transmission through a shaft combining. The gearbox bring along the major shaft, and the primary shaft bring along the rollers. So the roller began to turn 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 mixed with vapor or butter. The conditioning of the raw materials aims to improve the glue force and also developing price.



Then, the processed basic materials will be transferred to the pelletizing closet. Under the centrifugal force, they are dispersed 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 squeezed out from the ring die, they end up being strong cylindrical sticks. The sticks grow much longer, until they are cut by the slicer outside the ring die. After that the pellets fall down and also appear through the outlet.



2 kinds of ring die pellet machine

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



In the horizontal type, the ring die is put up and down. 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 put horizontally. The feed receptacle is right above the ring die, as well as the raw products falls under the ring die straight.



In the upright ring die pellet machine, both the roller and ring die rotate. richi pellet create centrifugal force and distribute basic materials consistently. In the horizontal ring die pellet machine, only 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 machine.

Ring die pellet mill includes high capability. 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 manufacturing demand is under 800kg, you 'd much better select flat die pellet machine, or ring die pellet machine is more suitable.



Due to the high manufacturing, the power intake each is reduced. The abrasion in between roller as well as die is smaller. The operation as well as maintenance is very easy. The pellets are consistent in dimension.
