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



Ring die pellet mill has huge quantity and also high ability. It appropriates for manufacturing facility usage as well as large-scale manufacturing. Flat die pellet mill is small as well as mobile. It has lower ability, ideal for residence usage and small-scale production. The cost of flat die pellet mill is much less than ring die pellet mill



Structure of flat die pellet mill.

Inside out, a flat die pellet mill is made up of a feed hopper, a top cabinet, a discharge outlet, a pin box, gear box, a transmission shaft, an electrical control cupboard, an electric motor, a engine base, as well as 4 wheels, and so on.



The electrical motor can be changed by a diesel engine, gas engine, or a PTO port.



The core parts: roller and also flat die

The pelletizing part of the flat die pellet machine is a press roller and also a flat die. They are set up in the top cupboard. There are 2-4 rollers set up on the 2 ends of the roller shaft. The rollers have grooves on the surface. The roller and flat die is constructed from remarkable alloy steel, whose firmness is 55-60 HRC.



There are lots of openings on the flat die, whose diameter is from 2.5 mm to 10mm, and 6mm, 8mm and 10mm are one of the most usual kinds. They understand the most effective compression proportion with a multitude of experiments, appropriate for more than 30 sort of products.



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



How does a flat die pellet machine job?

When you feed basic materials into the pellet machine with 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 also bring along the major shaft with the gearbox. Journalism roller is set up on the primary shaft, so it rotates around the major shaft. On the other hand, the rollers turn around the roller shaft.



The turning press forms strong pressure and press the raw products right into the holes on the flat die. The raw materials obtain built in these holes. When they are squeezed out, they become solid cylinders. At the same time, the strong friction in between roller and also die warm up the raw materials to over 80 ° C, where the lignin as well as fibers obtain soft. Extra resources enhance the glue pressure of products.



The diameter of the pellets is figured out by the opening dimension of the flat die, while the length is established 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 readjust the placement 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 out though the discharge electrical outlet.



2 types of flat die pellet equipment

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



Roller-turned type adopts much more reliable structure. It has larger ability and also even more long lasting transmission. But Die-turned kind is much more tiny and mobile, with lower expense. Obviously, both of them have the ability to make high-grade pellets.



Benefits and weak point of flat die pellet equipment

Flat die pellet mill has basic framework. It is small, light and also portable. The expense is much less than ring die pellet equipment It is very easy to operate and also maintain. You can observe the pelletizing process and also solve any mistake in time. So it is preferred with farmers, residence customers, and also small fuel production plant.



The flat dies are using parts, you need to replace it frequently. Yet it can be utilized with both sides. You can transform it over when one side has actually worn out. By doing this you can expand their working life and decrease price.



On the other hand, the moving range are different in the inner and also outer side of roller, which trigger the slide of rollers and also abrasion on the flat die. Currently, many flat die pellet machine take on conical roller to fix this issue. TICO flat die pellet machine adopts tapered roller and also exceptional alloy steel in the flat die.

Besides, the get in touch with area of roller and also flat die is smaller than ring die pellet machine, so the production capability as well as creating rate is reduced.



How does a ring die pellet machine job?

Structure of ring die pellet machine

A ring die pellet equipment is made up of a screw feeder, conditioner, roller as well as ring die, release port, electrical motor, transmission, stand.



The ring die pellet machine is driven by a direct-connected motor. The motor connect with the gearbox with a shaft coupling. The gearbox bring along the major shaft, and the primary shaft bring along the rollers. So the roller began to rotate inside the ring die.



When you feed resources right into the ring die pellet machine through the receptacle, they are transmitted to the conditioner, where the raw materials are mixed with vapor or butter. The conditioning of the raw materials aims to boost the adhesive pressure and also forming rate.



Then, the refined resources will be transmitted to the pelletizing cabinet. Under the centrifugal force, 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 high temperature as well as high pressure cause physical and also chemical modifications to the raw materials.



When they are squeezed out from the ring die, they become solid cylindrical sticks. The sticks grow much longer, up until they are reduced by the slicer outside the ring die. After that the pellets drop and also come out with the electrical outlet.



2 types of ring die pellet equipment

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




In the horizontal kind, the ring die is placed up and down. When basic materials fall down from the conditioner, they are fed into the ring die flat by a forced feeder. In the upright type, the ring die is positioned flat. The feed receptacle is right over the ring die, as well as the raw products comes under the ring die straight.



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



Benefits and weak point of ring die pellet machine.

Ring die pellet mill features high capacity. The manufacturing per hr is from 800kg to 20t. As for flat die pellet equipment, the ability is from 100kg/h to 1t/t. So if you manufacturing need is under 800kg, you 'd much better select flat die pellet equipment, or ring die pellet equipment is more suitable.



Because of the high manufacturing, the power consumption per unit is reduced. The abrasion between roller and die is smaller. The operation and upkeep is easy. The pellets are uniform in dimension.
