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



Ring die pellet mill has large volume as well as high capacity. It is suitable for factory use and also massive manufacturing. Apartment die pellet mill is tiny as well as portable. It has reduced capability, suitable for home usage as well as small-scale production. The rate of flat die pellet mill is a lot less than ring die pellet mill



Structure of flat die pellet mill.

From top to bottom, a flat die pellet mill is composed of a feed hopper, an upper cabinet, a discharge electrical outlet, a spindle box, gear box, a transmission shaft, an electrical control cabinet, an electrical motor, a engine base, as well as 4 wheels, etc.



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



The core parts: roller and also flat die

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



There are numerous openings on the flat die, whose size is from 2.5 mm to 10mm, and also 6mm, 8mm and 10mm are the most usual types. They realize the best compression proportion with a large number of experiments, ideal for greater than 30 type of materials.



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



Just how does a flat die pellet machine work?

When you feed raw materials into the pellet equipment with the receptacle, they fall on the flat die and spread over it under the feature of roller.



When you begin the pellet machine, the electrical motor runs and also bring along the major shaft with the transmission. Journalism roller is installed on the primary shaft, so it revolves around the primary shaft. At the same time, the rollers revolve around the roller shaft.



The rotating press forms solid stress and press the raw materials right into the holes on the flat die. The raw products obtain molded in these holes. When they are ejected, they end up being solid cylinders. At the same time, the strong friction in between roller and also die heat up the raw products to over 80 ° C, where the lignin and also fibers obtain soft. They raise the glue force of products.



The size of the pellets is established by the hole dimension of the flat die, while the size is figured out 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 particular size. You can readjust the position of slicer to transform the size.



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 out though the discharge outlet.



2 types of flat die pellet machine

Apartment die pellet mill can be classified into roller-turned type as well as die-turned kind. The former one has its flat die mounted on the primary shaft. When lab pellet press , the flat die rotates as well as the roller maintain still. The later one has journalism roller mounted on the primary shaft. The roller turns with the major shaft, while the flat die maintain still.



Roller-turned type takes on more effective framework. It has larger capacity as well as more durable transmission. But Die-turned type is much more tiny as well as portable, with lower cost. Certainly, both of them have the ability to make top quality pellets.



Advantages as well as weak point of flat die pellet equipment

Apartment die pellet mill has basic framework. It is small, light as well as portable. The expense is much less than ring die pellet machine It is very easy to run as well as preserve. You can observe the pelletizing process and also solve any mistake in time. So it is prominent with farmers, residence individuals, and also tiny fuel production plant.



The flat dies are wearing parts, you need to replace it consistently. But it can be utilized with both sides. You can transform it over when one side has worn. This way you can extend their working life and also lower cost.



On the other hand, the moving distance are various in the internal and also external side of roller, which create the slide of rollers as well as abrasion on the flat die. Presently, several flat die pellet machine take on conical roller to solve this trouble. TICO flat die pellet machine takes on conical roller and remarkable alloy steel in the flat die.

Besides, the contact area of roller and also flat die is smaller than ring die pellet machine, so the manufacturing capability and forming price is lower.



Just how does a ring die pellet equipment job?

Framework of ring die pellet machine

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



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



When you feed raw materials right into the ring die pellet machine via the receptacle, they are sent to the conditioner, where the raw materials are combined with vapor or butter. The conditioning of the raw materials intends to improve the sticky force and developing price.



Then, the refined raw materials will certainly be transmitted to the pelletizing closet. Under the centrifugal pressure, 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 high temperature and high pressure reason physical and also 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 longer, till they are cut by the slicer outside the ring die. After that the pellets fall down and appear with the outlet.



Two kinds of ring die pellet machine

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



In the horizontal type, the ring die is positioned up and down. When resources drop from the conditioner, they are fed into the ring die flat by a forced feeder. In the vertical kind, the ring die is put flat. The feed hopper is right over the ring die, and also the raw materials falls under the ring die directly.




In the vertical ring die pellet machine, both the roller as well as ring die turn. find out develop centrifugal force and disperse basic materials evenly. In the horizontal ring die pellet equipment, just the ring die rotates. The raw materials are distributed in the ring die by the screw feeder.



Benefits and weakness of ring die pellet machine.

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



As a result of the high production, the power consumption each is reduced. The abrasion in between roller as well as die is smaller. The procedure as well as maintenance is simple. The pellets are consistent in size.
