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



Ring die pellet mill has large quantity and high ability. image source is suitable for manufacturing facility use and also large-scale production. Apartment die pellet mill is little and also mobile. It has lower ability, ideal for house usage and small production. The rate of flat die pellet mill is a lot less than ring die pellet mill



Framework of flat die pellet mill.

Inside out, a flat die pellet mill is composed of a feed hopper, a top closet, a discharge electrical outlet, a spindle box, gear box, a transmission shaft, an electrical control closet, an electrical motor, a engine base, and 4 wheels, and so on.



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



The core components: 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 installed 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 area. The roller and also flat die is constructed from remarkable alloy steel, whose firmness is 55-60 HRC.



There are numerous openings on the flat die, whose diameter is from 2.5 mm to 10mm, as well as 6mm, 8mm and also 10mm are one of the most usual kinds. They recognize the best compression proportion with a multitude of experiments, ideal for more than 30 kinds 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 readjusting nuts on the side of the pellet mill, you can change the clearance to adapt to different materials.



How does a flat die pellet machine job?

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



When you begin the pellet equipment, the electric motor runs and also bring along the primary shaft via the transmission. The press roller is mounted on the major shaft, so it turns around the primary shaft. At the same time, the rollers revolve around the roller shaft.



The turning press forms strong stress as well as 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 cyndrical tubes. At the same time, the strong rubbing between roller and die heat up the raw products to over 80 ° C, where the lignin as well as fibers get soft. They raise the adhesive pressure of products.



The diameter of the pellets is established by the opening size of the flat die, while the length is figured out 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 into certain length. You can adjust 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 function of centrifugal pressure, the pellets are sent out though the discharge outlet.



Two kinds of flat die pellet machine

Apartment die pellet mill can be classified right into roller-turned type and die-turned type. The former one has its flat die installed on the major shaft. When the machine functions, the flat die rotates and the roller maintain still. The later one has journalism roller installed on the primary shaft. The roller revolves with the primary shaft, while the flat die maintain still.



Roller-turned kind adopts more effective framework. It has bigger ability and also even more durable transmission. However Die-turned type is much more little and also mobile, with reduced price. Of course, both of them have the ability to make top notch pellets.



Advantages and weak point of flat die pellet equipment


Apartment die pellet mill has easy structure. It is tiny, light and also mobile. The price is much less than ring die pellet machine It is easy to operate as well as maintain. You can observe the pelletizing process as well as address any kind of fault in time. So it is preferred with farmers, home customers, and also small gas production plant.



The flat dies are using parts, you need to replace it frequently. However it can be made use of with both sides. You can turn it over when one side has worn. By doing this you can expand their functioning life and also reduce price.



On the other hand, the moving distance are different in the inner and external side of roller, which create the slide of rollers as well as abrasion on the flat die. Currently, lots of flat die pellet equipment adopt tapered roller to address this problem. TICO flat die pellet machine embraces tapered roller as well as remarkable alloy steel in the flat die.

Besides, the call location of roller as well as flat die is smaller sized than ring die pellet equipment, so the production ability as well as forming price is reduced.



Just how does a ring die pellet machine job?

Framework of ring die pellet equipment

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



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



When you feed basic materials into the ring die pellet equipment with the hopper, they are sent to the conditioner, where the raw materials are mixed with vapor or butter. The conditioning of the raw materials intends to improve the adhesive pressure as well as creating price.



After that, the refined raw materials will certainly be sent to the pelletizing closet. Under the centrifugal force, they are distributed on the internal side of the ring die. The roller press the raw products into the holes on the ring die. The high temperature as well as high pressure reason physical as well as chemical changes to the raw products.



When they are squeezed out from the ring die, they end up being solid cylindrical sticks. The sticks grow longer, up until they are reduced by the slicer outside the ring die. Then the pellets fall down as well as come out with the electrical outlet.



Two sorts of ring die pellet equipment

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



In the straight type, the ring die is placed vertically. When raw materials drop from the conditioner, they are fed into the ring die horizontally by a forced feeder. In the upright type, the ring die is placed flat. Richi machine is right over the ring die, and the raw products falls under the ring die straight.



In the upright ring die pellet machine, both the roller as well as ring die revolve. They form centrifugal force and also disperse resources uniformly. In the horizontal ring die pellet machine, only the ring die rotates. The raw materials are distributed in the ring die by the screw feeder.



Benefits as well as weakness of ring die pellet machine.

Ring die pellet mill includes high capacity. The manufacturing per hour is from 800kg to 20t. As for flat die pellet equipment, the ability is from 100kg/h to 1t/t. So if you production requirement is under 800kg, you 'd much better choose flat die pellet equipment, or ring die pellet machine is better.



Because of the high manufacturing, the power intake each is reduced. The abrasion in between roller and die is smaller. The procedure and upkeep is very easy. The pellets are consistent in dimension.
