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



Ring die pellet mill has big volume as well as high ability. It is suitable for factory usage as well as large manufacturing. Apartment die pellet mill is little and also portable. It has lower ability, appropriate for residence use as well as 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 composed of a feed receptacle, an upper cabinet, a discharge electrical outlet, a pin box, transmission, a transmission shaft, an electric control closet, an electric motor, a engine base, and 4 wheels, etc.



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



The core parts: roller as well as flat die

The pelletizing part of the flat die pellet equipment is a press roller and a flat die. They are mounted in the top cupboard. There are 2-4 rollers installed on the 2 ends of the roller shaft. The rollers have grooves on the surface area. The roller and also flat die is made of premium alloy steel, whose solidity is 55-60 HRC.



There are many openings on the flat die, whose size is from 2.5 mm to 10mm, and 6mm, 8mm as well as 10mm are the most usual types. They understand the very best compression ratio with a lot of experiments, appropriate for greater than 30 sort of materials.



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



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 begin the pellet equipment, the electrical motor runs and bring along the main shaft via the gearbox. The press roller is set up 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 types solid stress and press the raw products into the holes on the flat die. The raw products obtain formed in these holes. When they are ejected, they become solid cyndrical tubes. At the same time, the strong rubbing between roller and die heat up the raw materials to over 80 ° C, where the lignin and also fibers obtain soft. They enhance the adhesive force of products.



The size of the pellets is identified by the hole size of the flat die, while the size is identified by the slicer under the flat die. When the biomass pellets appear in the shape of cyndrical tubes, the slicer under the flat die cut them right into specific length. You can change the setting of slicer to change the size.



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



Two sorts of flat die pellet equipment

Apartment die pellet mill can be classified right into roller-turned kind and die-turned kind. The former one has its flat die mounted on the major shaft. When the machine functions, the flat die rotates and the roller maintain still. The later one has the press roller mounted on the main shaft. The roller turns with the main shaft, while the flat die maintain still.



Roller-turned kind adopts a lot more effective structure. It has larger ability and also even more long lasting transmission. But bühler pellet mill manual -turned type is extra small as well as mobile, with lower price. Certainly, both of them have the ability to make premium pellets.



Benefits and weakness of flat die pellet equipment

Flat die pellet mill has straightforward structure. It is small, light and mobile. The expense is much lower than ring die pellet machine It is very easy to run as well as preserve. You can observe the pelletizing process as well as resolve any mistake in time. So it is popular with farmers, house users, as well as small gas production plant.



The flat dies are using parts, you require to replace it regularly. However it can be made use of with both sides. You can turn it over when one side has actually broken. This way you can prolong their functioning life as well as reduce cost.



On the other hand, the relocating range 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, many flat die pellet machine adopt conical roller to address this issue. TICO flat die pellet machine takes on tapered roller and premium alloy steel in the flat die.

Besides, the get in touch with location of roller as well as flat die is smaller sized than ring die pellet machine, so the manufacturing capability and also forming price is reduced.



How does a ring die pellet equipment work?

Framework of ring die pellet machine

A ring die pellet machine is composed of a screw feeder, conditioner, roller as well as ring die, release port, electrical motor, transmission, pedestal.



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



When you feed resources into the ring die pellet equipment with the receptacle, they are sent to the conditioner, where the raw products are combined with vapor or butter. Richi machine of the raw products intends to enhance the adhesive pressure and also developing price.



Then, the refined resources will certainly be transmitted to the pelletizing closet. Under the centrifugal pressure, they are distributed on the internal side of the ring die. The roller press the raw materials right into the holes on the ring die. The high temperature as well as high pressure reason physical and also chemical adjustments to the raw materials.



When they are squeezed out from the ring die, they become solid cylindrical sticks. The sticks expand much longer, up until they are reduced by the slicer outside the ring die. Then the pellets fall down as well as appear via the electrical outlet.



Two kinds of ring die pellet machine

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



In the horizontal kind, the ring die is positioned up and down. When raw materials fall down from the conditioner, they are fed into the ring die flat by a forced feeder. In the vertical type, the ring die is put horizontally. The feed receptacle is right above the ring die, as well as the raw materials falls into the ring die directly.



In the upright ring die pellet machine, both the roller and also ring die revolve. They form centrifugal force and also distribute raw materials evenly. In the straight ring die pellet machine, only the ring die rotates. The raw products are distributed in the ring die by the screw feeder.



Benefits and weakness of ring die pellet equipment.

Ring die pellet mill includes 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 production demand is under 800kg, you would certainly better choose flat die pellet machine, or ring die pellet machine is preferable.



As a result of the high production, the power usage per unit is low. The abrasion in between roller as well as die is smaller. The procedure as well as upkeep is easy. The pellets are consistent in size.
