Exactly how does a wood pellet machine job?<br>
Typically, wood pellet machine can be classified into flat die pellet equipment as well as ring die pellet machine.



Ring die pellet mill has huge quantity and high capability. It appropriates for manufacturing facility usage and also massive production. https://richipelletequipment.livedoor.biz/archives/19540809.html is little as well as portable. It has reduced capability, appropriate for residence usage and small-scale manufacturing. The rate of flat die pellet mill is much less than ring die pellet mill



Framework of flat die pellet mill.

Inside out, a flat die pellet mill is made up of a feed hopper, an upper cabinet, a discharge outlet, a spindle box, transmission, a transmission shaft, an electric control closet, an electrical motor, a engine base, and 4 wheels, and so on.



The electrical motor can be changed by a diesel motor, gas engine, or a PTO port.



The core parts: roller and flat die

The pelletizing part of the flat die pellet equipment is a press roller and a flat die. They are installed in the upper closet. There are 2-4 rollers installed 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 remarkable alloy steel, whose firmness is 55-60 HRC.



There are several holes on the flat die, whose size is from 2.5 mm to 10mm, as well as 6mm, 8mm and 10mm are the most typical kinds. They understand the best compression ratio with a multitude of experiments, appropriate for more than 30 type of products.



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



How does a flat die pellet machine job?

When you feed raw materials right into the pellet machine via the hopper, they fall on the flat die and also spread over it under the function of roller.



When you start the pellet equipment, the electric motor runs and also bring along the primary shaft via the gearbox. Journalism roller is installed on the major shaft, so it turns around the main shaft. At https://pelletrichi.hatenadiary.com/entry/2023/03/10/150443 , the rollers rotate around the roller shaft.



The turning press forms solid pressure as well as press the raw materials right into the holes on the flat die. The raw products get built in these openings. When they are squeezed out, they come to be strong cylinders. At the same time, the solid friction in between roller and die warm up the raw products to over 80 ° C, where the lignin and fibers obtain soft. They raise the sticky force of materials.



The diameter of the pellets is identified by the hole dimension of the flat die, while the length is established by the slicer under the flat die. When the biomass pellets appear in the form of cyndrical tubes, the slicer under the flat die reduced them into specific length. You can change the position of slicer to alter the size.



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 out though the discharge electrical outlet.



2 sorts of flat die pellet equipment

Apartment die pellet mill can be classified right into roller-turned kind as well as die-turned kind. The previous one has its flat die mounted on the primary shaft. When the equipment works, the flat die revolves as well as the roller maintain still. The later one has journalism roller installed on the main shaft. The roller revolves with the primary shaft, while the flat die maintain still.



Roller-turned kind takes on much more effective framework. It has bigger ability and also more long lasting gearbox. But Die-turned type is more small as well as mobile, with lower expense. Obviously, both of them are able to make high-grade pellets.



Advantages as well as weakness of flat die pellet equipment

Flat die pellet mill has simple framework. It is tiny, light as well as portable. The cost is a lot less than ring die pellet machine It is easy to operate and also preserve. You can observe the pelletizing process and also resolve any fault in time. So it is preferred with farmers, home individuals, as well as small gas production plant.



The flat dies are putting on components, you require to change it routinely. However it can be utilized with both sides. You can transform it over when one side has actually broken. This way you can expand their working life and also decrease expense.



On the other hand, the moving distance are different in the internal as well as outer side of roller, which cause the slide of rollers as well as abrasion on the flat die. Currently, several flat die pellet equipment embrace tapered roller to address this problem. TICO flat die pellet machine adopts tapered roller and remarkable alloy steel in the flat die.

Besides, the contact area of roller and also flat die is smaller sized than ring die pellet equipment, so the manufacturing capacity and creating price is reduced.



How does a ring die pellet machine work?

Structure of ring die pellet machine

A ring die pellet equipment is made up of a screw feeder, conditioner, roller as well as ring die, release port, electrical motor, gearbox, stand.



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



When you feed basic materials into the ring die pellet machine via the hopper, they are transferred to the conditioner, where the raw materials are combined with vapor or butter. The conditioning of the raw materials intends to enhance the adhesive force as well as developing rate.



Then, the refined resources will be transferred to the pelletizing cupboard. Under the centrifugal pressure, they are distributed on the internal side of the ring die. The roller press the raw materials into the holes on the ring die. The high temperature and also high pressure cause physical as well as chemical changes to the raw materials.



When they are squeezed out from the ring die, they come to be strong cylindrical sticks. The sticks expand much longer, until they are reduced by the slicer outside the ring die. After that the pellets drop and appear through the electrical outlet.



Two types of ring die pellet equipment

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



In the horizontal type, the ring die is positioned vertically. When resources fall down from the conditioner, they are fed into the ring die horizontally by a forced feeder. In the upright type, the ring die is positioned horizontally. The feed receptacle is right above the ring die, as well as the raw products comes under the ring die directly.



In the vertical ring die pellet machine, both the roller and also ring die rotate. They develop centrifugal force and distribute basic materials evenly. In the horizontal ring die pellet equipment, only the ring die rotates. The raw materials are distributed in the ring die by the screw feeder.




Benefits and also weak point of ring die pellet equipment.

Ring die pellet mill includes high capability. The manufacturing per hour is from 800kg to 20t. When it comes to flat die pellet machine, the capacity is from 100kg/h to 1t/t. So if you manufacturing requirement is under 800kg, you would certainly much better pick flat die pellet machine, or ring die pellet equipment is better.



Because of the high manufacturing, the power intake per unit is reduced. The abrasion between roller and die is smaller sized. The procedure and also maintenance is very easy. The pellets are uniform in size.
