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



Ring die pellet mill has large volume as well as high ability. It appropriates for manufacturing facility usage as well as large production. Flat die pellet mill is little and also portable. It has reduced ability, appropriate for residence use as well as small-scale manufacturing. The cost of flat die pellet mill is much 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 hopper, a top cabinet, a discharge outlet, a pin box, transmission, a transmission shaft, an electrical control closet, an electric motor, a engine base, and also 4 wheels, and so on.



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



The core components: roller as well as flat die

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



There are many holes on the flat die, whose size is from 2.5 mm to 10mm, as well as 6mm, 8mm and also 10mm are one of the most typical types. They recognize the best compression proportion with a lot of experiments, suitable for more than 30 sort of products.



The clearance between the roller and flat die is 0.1-0.3 mm. This is where the raw product layer kinds. There are 2 changing nuts on the side of the pellet mill, you can change the clearance to adjust to different products.



Exactly how does a flat die pellet machine job?

When you feed raw materials right into the pellet machine 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 electrical motor runs and also bring along the main shaft with the gearbox. The press roller is mounted on the major shaft, so it revolves around the major shaft. At the same time, the rollers revolve around the roller shaft.



The revolving press types solid pressure as well as press the raw products right into the holes on the flat die. The raw products get molded in these openings. When they are ejected, they come to be solid cyndrical tubes. On the other hand, the strong rubbing between roller as well as die warm up the raw materials to over 80 ° C, where the lignin and also fibers obtain soft. They increase the glue force of products.



The size of the pellets is figured out by the opening 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 form of cylinders, the slicer under the flat die reduced them into particular length. You can change the placement of slicer to alter the length.



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



Two types of flat die pellet equipment

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



Roller-turned type embraces a lot more effective structure. It has bigger capability and also even more sturdy gearbox. However Die-turned kind is more tiny and portable, with lower price. Naturally, both of them are able to make high-grade pellets.



Advantages and weakness of flat die pellet machine


Flat die pellet mill has easy framework. It is small, light and also mobile. The expense is much lower than ring die pellet equipment It is simple to run as well as maintain. You can observe the pelletizing process and also fix any mistake in time. So it is prominent with farmers, house individuals, and tiny gas manufacturing plant.



The flat dies are using components, you need to replace it on a regular basis. However it can be utilized with both sides. You can transform it over when one side has actually worn. By doing this you can prolong their working life as well as lower cost.



On the other hand, the moving range are various in the internal and external side of roller, which cause the slide of rollers and also abrasion on the flat die. Presently, many flat die pellet equipment embrace conical roller to fix this problem. TICO flat die pellet equipment takes on conical roller and also premium alloy steel in the flat die.

Besides, the get in touch with location of roller as well as flat die is smaller than ring die pellet equipment, so the production capacity and also developing rate is reduced.



Just how does a ring die pellet equipment job?

Framework of ring die pellet equipment

A ring die pellet machine is composed of a screw feeder, conditioner, roller as well as ring die, release port, electric motor, gearbox, stand.



The ring die pellet machine is driven by a direct-connected motor. The electric motor connect with the gearbox through a shaft combining. The gearbox bring along the primary shaft, and also the main shaft bring along the rollers. So the roller started to turn inside the ring die.



When you feed raw materials right into the ring die pellet machine via the hopper, they are transmitted to the conditioner, where the raw materials are blended with vapor or butter. The conditioning of the raw materials aims to improve the glue pressure and forming price.



Then, the refined raw materials will be sent to the pelletizing cabinet. Under the centrifugal pressure, they are dispersed on the inner side of the ring die. The roller press the raw materials right into the holes on the ring die. The heat and high pressure cause physical as well as chemical changes to the raw products.



When they are ejected from the ring die, they end up being strong round sticks. The sticks grow much longer, till they are cut by the slicer outside the ring die. After that the pellets drop and come out through the outlet.



Two kinds of ring die pellet machine

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




In the horizontal type, the ring die is put vertically. When resources drop from the conditioner, they are fed into the ring die horizontally by a forced feeder. In the vertical type, the ring die is positioned horizontally. The feed hopper is right over the ring die, and also the raw products falls under the ring die straight.



In the upright ring die pellet equipment, both the roller and also ring die turn. They create centrifugal force as well as disperse basic materials uniformly. 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 as well as weak point of ring die pellet machine.

Ring die pellet mill includes high ability. The manufacturing per hr is from 800kg to 20t. As for flat die pellet equipment, the ability is from 100kg/h to 1t/t. So if you manufacturing requirement is under 800kg, you would certainly better pick flat die pellet equipment, or ring die pellet equipment is more suitable.



Because of the high production, the power usage per unit is reduced. The abrasion between roller as well as die is smaller. The procedure and upkeep is easy. The pellets are consistent in size.
