How does a wood pellet machine job?<br>
Normally, chicken feed pellet mill can be classified into flat die pellet equipment and also ring die pellet machine.



Ring die pellet mill has large volume and high ability. rabbit pellet machine is suitable for factory usage and large manufacturing. Apartment die pellet mill is little and mobile. It has lower capacity, suitable for home usage as well as small production. The price of flat die pellet mill is much lower 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 receptacle, an upper cabinet, a discharge electrical outlet, a spindle box, transmission, a transmission shaft, an electrical control closet, an electric motor, a engine base, and also 4 wheels, and so on.



The electric motor can be replaced by a diesel motor, gasoline engine, or a PTO port.



The core parts: roller and also 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 as well as flat die is made from exceptional alloy steel, whose firmness is 55-60 HRC.



There are many holes on the flat die, whose diameter is from 2.5 mm to 10mm, as well as 6mm, 8mm and 10mm are the most typical kinds. They realize the best compression ratio with a great deal of experiments, appropriate for more than 30 type of products.



The clearance between the roller as well as flat die is 0.1-0.3 mm. This is where the raw material layer forms. There are 2 changing nuts on the side of the pellet mill, you can readjust the clearance to adapt to different materials.




Just how does a flat die pellet equipment job?

When you feed resources right into the pellet machine through the hopper, they fall on the flat die and also spread over it under the feature of roller.



When you start the pellet equipment, the electric motor runs and bring along the primary shaft with the gearbox. The press roller is set up on the main shaft, so it rotates around the major shaft. On the other hand, the rollers rotate around the roller shaft.



The revolving press types strong pressure and also press the raw materials right into the holes on the flat die. The raw products get formed in these holes. When they are squeezed out, they become strong cyndrical tubes. At the same time, the solid friction in between roller and die heat up the raw materials to over 80 ° C, where the lignin and also fibers get soft. They raise the adhesive pressure of materials.



The diameter of the pellets is identified by the hole 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 cylinders, the slicer under the flat die reduced them into particular size. You can readjust the placement of slicer to change the size.



After being cut 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 electrical outlet.



Two types of flat die pellet machine

Flat die pellet mill can be classified into roller-turned type and die-turned type. The previous one has its flat die set up on the main shaft. When the machine works, the flat die revolves and the roller maintain still. The later one has the press roller set up on the major shaft. The roller turns with the major shaft, while the flat die maintain still.



Roller-turned kind takes on extra reliable framework. It has larger capability and also more sturdy gearbox. However Die-turned kind is more little as well as portable, with reduced expense. Of course, both of them have the ability to make high-grade pellets.



Benefits and weak point of flat die pellet equipment

Apartment die pellet mill has simple structure. It is tiny, light as well as mobile. The cost is a lot lower than ring die pellet machine It is easy to run and maintain. You can observe the pelletizing process and address any fault in time. So it is prominent with farmers, house individuals, as well as tiny fuel production plant.



The flat dies are wearing parts, you require to change it frequently. But it can be made use of with both sides. You can turn it over when one side has actually worn. By doing this you can prolong their working life and reduce cost.




On the other hand, the relocating range are various in the inner as well as external side of roller, which cause the slide of rollers and abrasion on the flat die. Currently, lots of flat die pellet machine embrace tapered roller to fix this trouble. TICO flat die pellet equipment adopts conical roller as well as remarkable alloy steel in the flat die.

Besides, the get in touch with location of roller and also flat die is smaller than ring die pellet machine, so the production capacity and forming price is lower.



Just how does a ring die pellet equipment job?

Framework of ring die pellet machine

A ring die pellet equipment is made up of a screw feeder, conditioner, roller and ring die, release port, electric motor, transmission, pedestal.



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



When you feed resources into the ring die pellet equipment via the hopper, they are transferred to the conditioner, where the raw materials are mixed with vapor or butter. The conditioning of the raw products intends to enhance the glue force and also forming rate.



After that, the processed resources will be sent 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 heat and high pressure cause physical and chemical adjustments to the raw materials.



When they are squeezed out from the ring die, they become strong round sticks. The sticks grow longer, until they are reduced by the slicer outside the ring die. After that the pellets fall down and also appear with the outlet.



Two types of ring die pellet machine

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



In the straight kind, the ring die is put vertically. 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 placed horizontally. The feed hopper is right above the ring die, and also the raw materials comes under the ring die directly.



In the vertical ring die pellet equipment, both the roller and ring die revolve. They develop centrifugal pressure as well as disperse basic materials consistently. In the horizontal ring die pellet equipment, 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 features 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 would certainly better select flat die pellet machine, or ring die pellet machine is more suitable.



Because of the high manufacturing, the power intake each is low. The abrasion between roller as well as die is smaller. The operation as well as maintenance is simple. The pellets are uniform in dimension.
