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



Ring die pellet mill has large volume and also high capacity. It appropriates for factory usage and large manufacturing. Flat die pellet mill is tiny and portable. It has reduced capacity, suitable for residence use and small-scale manufacturing. The cost of flat die pellet mill is much lower than ring die pellet mill



Framework of flat die pellet mill.

Inside out, a flat die pellet mill is composed of a feed receptacle, an upper closet, a discharge outlet, a spindle box, gear box, a transmission shaft, an electric control closet, an electric motor, a engine base, as well as 4 wheels, and so on.



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



The core components: roller and flat die

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



There are numerous holes on the flat die, whose size is from 2.5 mm to 10mm, and 6mm, 8mm and 10mm are one of the most typical types. They realize the best compression proportion with a large number of experiments, appropriate for more than 30 type of products.



The clearance in between the roller and also flat die is 0.1-0.3 mm. This is where the raw material layer types. There are feed pelletizer for sale adjusting nuts on the side of the pellet mill, you can readjust the clearance to adjust to different products.



How does a flat die pellet equipment work?

When you feed basic materials into the pellet machine with the receptacle, they fall on the flat die as well as spread over it under the function of roller.



When you start the pellet machine, the electrical motor runs and bring along the major shaft through the transmission. Journalism roller is installed on the main shaft, so it revolves around the primary shaft. At the same time, the rollers turn around the roller shaft.



The rotating press types strong stress and press the raw materials right into the holes on the flat die. The raw materials get built in these openings. When they are ejected, they become solid cylinders. At the same time, the strong friction in between roller as well as die warm up the raw products to over 80 ° C, where the lignin and fibers get soft. They enhance the adhesive pressure of materials.



The diameter of the pellets is figured out by the opening dimension of the flat die, while the size is determined by the slicer under the flat die. When the biomass pellets appear in the form of cyndrical tubes, the slicer under the flat die cut them into specific size. You can readjust the setting of slicer to transform the length.



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



2 sorts of flat die pellet machine

Flat die pellet mill can be classified into roller-turned type as well as die-turned kind. The previous one has its flat die set up on the primary shaft. When the equipment works, the flat die revolves as well as the roller keep still. The later one has journalism roller mounted on the major shaft. The roller turns with the primary shaft, while the flat die maintain still.



Roller-turned kind takes on a lot more reliable structure. It has larger capacity and also more durable transmission. But Die-turned type is extra little and also portable, with lower cost. Certainly, both of them have the ability to make premium pellets.



Benefits and weak point of flat die pellet machine

Apartment die pellet mill has basic structure. It is little, light as well as mobile. The price is much less than ring die pellet equipment It is easy to operate and preserve. You can observe the pelletizing procedure as well as solve any fault in time. So it is popular with farmers, home customers, as well as little fuel manufacturing plant.



The flat dies are wearing components, you require to change it routinely. However it can be made use of with both sides. You can turn it over when one side has actually worn out. In this way you can extend their functioning life as well as lower cost.



On the other hand, the moving range are different in the inner and outer side of roller, which cause the slide of rollers as well as abrasion on the flat die. Presently, many flat die pellet machine adopt conical roller to fix this problem. TICO flat die pellet machine takes on tapered roller as well as superior alloy steel in the flat die.

Besides, the call location of roller and flat die is smaller than ring die pellet machine, so the production ability and developing rate is reduced.



Exactly how does a ring die pellet equipment work?

Framework of ring die pellet machine

A ring die pellet equipment is made up of a screw feeder, conditioner, roller and 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 gearbox with a shaft coupling. The transmission bring along the main shaft, and the main shaft bring along the rollers. So the roller began to rotate inside the ring die.



When you feed basic materials into the ring die pellet machine with the receptacle, they are sent to the conditioner, where the raw products are blended with vapor or butter. The conditioning of the raw products intends to improve the glue force and also creating price.



After that, the processed basic materials will certainly be transferred to the pelletizing cupboard. Under the centrifugal force, 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 heat and also high pressure cause physical as well as chemical changes to the raw products.



When they are ejected from the ring die, they become strong round sticks. The sticks grow longer, until they are reduced by the slicer outside the ring die. Then the pellets fall down and appear with the electrical outlet.



2 types of ring die pellet machine


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



In the straight type, the ring die is put up and down. When raw materials drop from the conditioner, they are fed right into the ring die horizontally by a forced feeder. In the upright type, the ring die is placed flat. The feed hopper is right above the ring die, and also the raw products comes under the ring die directly.



In the vertical ring die pellet equipment, both the roller and also ring die turn. They develop centrifugal pressure and distribute raw materials evenly. In richi pellet mill , only the ring die rotates. The raw materials are dispersed in the ring die by the screw feeder.



Advantages and weak point of ring die pellet equipment.

Ring die pellet mill includes high ability. The manufacturing per hour is from 800kg to 20t. When it comes to flat die pellet machine, the capability is from 100kg/h to 1t/t. So if you manufacturing need is under 800kg, you 'd better pick flat die pellet equipment, or ring die pellet machine is preferable.



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