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



Ring die pellet mill has large volume and also high ability. It is suitable for manufacturing facility use and large manufacturing. Flat die pellet mill is little and also portable. It has lower capacity, ideal for home use and also small manufacturing. The rate of flat die pellet mill is a lot 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 receptacle, an upper closet, a discharge electrical outlet, a pin box, gear box, a transmission shaft, an electric control closet, an electrical motor, a engine base, as well as 4 wheels, etc.



The electrical motor can be replaced by a diesel motor, gasoline engine, or a PTO connector.



The core components: roller and also flat die

The pelletizing part of the flat die pellet machine is a press roller as well as a flat die. They are installed in the upper 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 exceptional alloy steel, whose firmness is 55-60 HRC.



There are several holes on the flat die, whose diameter is from 2.5 mm to 10mm, as well as 6mm, 8mm as well as 10mm are one of the most typical types. They understand the most effective compression ratio with a lot of experiments, appropriate for greater than 30 kinds of materials.



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



Exactly how does a flat die pellet equipment job?

When you feed raw materials right into the pellet machine through the receptacle, they fall on the flat die as well as spread over it under the feature of roller.



When you start the pellet equipment, the electric motor runs and also bring along the primary shaft via the gearbox. The press roller is mounted on the primary shaft, so it revolves around the main shaft. At the same time, the rollers rotate around the roller shaft.




The rotating press forms solid pressure and also press the raw materials right into the holes on the flat die. The raw products obtain built in these openings. When they are ejected, they end up being solid cyndrical tubes. Meanwhile, the strong rubbing 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 increase the adhesive force of materials.



The size of the pellets is identified by the opening size of the flat die, while the size is identified by the slicer under the flat die. When the biomass pellets come out in the shape of cylinders, the slicer under the flat die cut them into specific size. You can change the placement of slicer to transform the length.



After being reduced 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 sorts of flat die pellet machine

Flat die pellet mill can be classified into roller-turned kind and die-turned kind. The former one has its flat die installed on the primary shaft. When the machine functions, the flat die rotates as well as the roller keep still. The later one has the press roller mounted on the primary shaft. The roller revolves with the primary shaft, while the flat die maintain still.



Roller-turned type adopts a lot more efficient framework. It has bigger capability as well as more sturdy gearbox. Yet Die-turned type is a lot more little as well as mobile, with lower price. Certainly, both of them are able to make high-grade pellets.




Advantages and weakness of flat die pellet equipment

Flat die pellet mill has basic framework. It is little, light and portable. The cost is a lot less than ring die pellet equipment It is simple to run and preserve. You can observe the pelletizing process and also address any kind of mistake in time. So it is prominent with farmers, house users, as well as little gas manufacturing plant.



The flat dies are putting on parts, you require to replace it on a regular basis. But homemade pellet press can be utilized with both sides. You can turn it over when one side has worn out. This way you can extend their working life as well as minimize expense.



On the other hand, the relocating distance are various in the internal as well as outer side of roller, which cause the slide of rollers and abrasion on the flat die. Presently, many flat die pellet equipment take on conical roller to address this trouble. TICO flat die pellet equipment takes on tapered roller and superior alloy steel in the flat die.

Besides, the call area of roller and also flat die is smaller sized than ring die pellet machine, so the manufacturing capacity and developing price is lower.



Exactly how does a ring die pellet equipment work?

Structure of ring die pellet machine

A ring die pellet machine is made up of a screw feeder, conditioner, roller as well as ring die, discharge port, electric motor, transmission, stand.



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



When you feed raw materials into the ring die pellet machine through the hopper, they are transferred to the conditioner, where the raw materials are mixed with vapor or butter. The conditioning of the raw materials intends to improve the sticky force as well as developing price.



Then, the processed resources will certainly be transmitted to the pelletizing cabinet. Under the centrifugal pressure, they are distributed on the inner 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 and also chemical adjustments to the raw materials.



When they are ejected from the ring die, they end up being strong cylindrical sticks. The sticks expand longer, up until they are reduced by the slicer outside the ring die. Then the pellets drop and come out with the electrical outlet.



Two types of ring die pellet machine

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



In the horizontal kind, the ring die is put up and down. 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 flat. The feed receptacle is right over the ring die, and the raw products comes under the ring die straight.



In the upright ring die pellet equipment, both the roller as well as ring die revolve. They develop centrifugal force as well as distribute resources consistently. In the straight ring die pellet equipment, just the ring die rotates. The raw products are dispersed in the ring die by the screw feeder.



Advantages and weak point of ring die pellet equipment.

Ring die pellet mill features high ability. The manufacturing per hour is from 800kg to 20t. As for flat die pellet equipment, the capability is from 100kg/h to 1t/t. So if you manufacturing need is under 800kg, you 'd better choose flat die pellet machine, or ring die pellet equipment is more suitable.



As a result of the high production, the power usage per unit is reduced. The abrasion in between roller and die is smaller sized. The operation and also upkeep is easy. The pellets are uniform in dimension.
