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



Ring die pellet mill has large quantity as well as high capability. It appropriates for factory usage and also massive manufacturing. Flat die pellet mill is tiny and portable. It has reduced capability, suitable for home use and also small manufacturing. The price 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 hopper, an upper cabinet, a discharge outlet, a spindle box, transmission, a transmission shaft, an electric control closet, an electric motor, a engine base, and also 4 wheels, and so on.



The electrical motor can be changed by a diesel motor, fuel 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. richi pellet mill are installed in the top cupboard. There are 2-4 rollers mounted on the 2 ends of the roller shaft. The rollers have grooves on the surface. The roller and also flat die is made of exceptional alloy steel, whose solidity is 55-60 HRC.



There are lots of holes on the flat die, whose diameter is from 2.5 mm to 10mm, and 6mm, 8mm and also 10mm are one of the most usual kinds. They recognize the very best compression ratio with a multitude of experiments, suitable for more than 30 sort of products.



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



Just how does a flat die pellet machine work?

When you feed resources right into the pellet equipment through the receptacle, they fall on the flat die as well as spread over it under the feature of roller.



When you start the pellet machine, the electrical motor runs and also bring along the primary shaft through the gearbox. Journalism roller is installed on the primary shaft, so it turns around the major shaft. Meanwhile, the rollers turn around the roller shaft.



The revolving press kinds strong stress and press the raw products right into the holes on the flat die. The raw materials get molded in these openings. When they are ejected, they become strong cyndrical tubes. Meanwhile, the strong rubbing between roller and die heat up the raw products to over 80 ° C, where the lignin and fibers get soft. They enhance the sticky pressure of materials.



The size of the pellets is figured out by the opening size of the flat die, while the length is identified by the slicer under the flat die. When the biomass pellets appear in the shape of cylinders, the slicer under the flat die reduced them into certain size. You can adjust the position 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 pressure, the pellets are sent though the discharge outlet.



2 types of flat die pellet equipment

Apartment die pellet mill can be classified right into roller-turned kind as well as die-turned type. The previous one has its flat die set up on the primary shaft. When the equipment functions, the flat die turns as well as the roller maintain still. The later one has the press roller set up on the major shaft. The roller turns with the main shaft, while the flat die maintain still.



Roller-turned type adopts extra efficient framework. It has bigger ability and even more sturdy gearbox. Yet Die-turned kind is extra little and portable, with reduced price. Of chicken feed pellet making machine , both of them are able to make top quality pellets.



Benefits as well as weak point of flat die pellet machine

Flat die pellet mill has basic structure. It is small, light as well as portable. The cost is a lot less than ring die pellet equipment It is simple to run as well as preserve. You can observe the pelletizing process and fix any type of fault in time. So it is popular with farmers, home users, and small fuel production plant.



The flat dies are using parts, you need to replace it on a regular basis. But biomass wood pellet machine can be used with both sides. You can transform it over when one side has worn out. By doing this you can extend their functioning life as well as reduce price.



On the other hand, the moving distance are different in the internal as well as outer side of roller, which cause the slide of rollers as well as abrasion on the flat die. Presently, many flat die pellet equipment take on conical roller to address this issue. TICO flat die pellet machine adopts conical roller as well as remarkable alloy steel in the flat die.

Besides, the contact area of roller and also flat die is smaller than ring die pellet machine, so the manufacturing capacity as well as forming rate is reduced.



Exactly how does a ring die pellet equipment work?

Structure of ring die pellet equipment

A ring die pellet machine is made up of a screw feeder, conditioner, roller as well as ring die, discharge port, electric motor, transmission, pedestal.



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



When you feed basic materials 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 improve the sticky pressure and creating rate.



Then, the refined basic materials will be transferred to the pelletizing cupboard. Under the centrifugal pressure, they are distributed on the inner 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 cause physical and also chemical changes to the raw products.



When they are ejected from the ring die, they come to be strong round sticks. The sticks grow much longer, up until they are cut by the slicer outside the ring die. Then the pellets fall down and appear through the outlet.



2 kinds of ring die pellet equipment

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




In the straight type, the ring die is put vertically. When basic materials drop from the conditioner, they are fed right into the ring die horizontally by a forced feeder. In the vertical type, the ring die is positioned horizontally. The feed receptacle is right over the ring die, and also the raw products falls under the ring die directly.



In the upright ring die pellet machine, both the roller as well as ring die rotate. They form centrifugal pressure and distribute raw materials consistently. In the horizontal ring die pellet equipment, just the ring die rotates. The raw materials are distributed in the ring die by the screw feeder.



Advantages and weak point 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 capability is from 100kg/h to 1t/t. So if you manufacturing requirement is under 800kg, you 'd better pick flat die pellet equipment, or ring die pellet machine is preferable.



Due to the high production, the power usage per unit is low. The abrasion in between roller and die is smaller sized. The operation as well as maintenance is very easy. The pellets are uniform in dimension.
