How does a wood pellet machine work
Exactly how does a wood pellet machine job?
Usually, wood pellet equipment can be classified right into flat die pellet equipment and also ring die pellet equipment.

Ring die pellet mill has large quantity and high ability. It is suitable for factory use and also large manufacturing. Apartment die pellet mill is tiny and portable. It has lower ability, appropriate for home usage and also small-scale manufacturing. The cost of flat die pellet mill is much less 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, a top closet, a discharge electrical outlet, a spindle box, transmission, a transmission shaft, an electrical control closet, an electrical motor, a engine base, as well as 4 wheels, etc.

The electric 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 mounted in the top closet. 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 premium alloy steel, whose firmness is 55-60 HRC.

There are several openings on the flat die, whose size is from 2.5 mm to 10mm, as well as 6mm, 8mm as well as 10mm are one of the most typical types. They realize the best compression proportion with a multitude of experiments, ideal for more than 30 sort of materials.

The clearance between the roller and also 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 adjust the clearance to adapt to various materials.

Just how does a flat die pellet equipment job?
When you feed resources right into the pellet equipment via the receptacle, they fall on the flat die as well as spread over it under the function of roller.

When small feed pellet mill begin the pellet equipment, the electric motor runs and also bring along the primary shaft with the gearbox. Journalism roller is set up on the main shaft, so it rotates around the primary shaft. Meanwhile, the rollers revolve around the roller shaft.

The rotating press types strong pressure and also press the raw products into the holes on the flat die. The raw materials get built in these holes. When they are ejected, they end up being solid cylinders. On the other hand, the strong rubbing between roller and die heat up the raw materials to over 80 ° C, where the lignin as well as fibers obtain soft. They raise the adhesive pressure of products.

The size of the pellets is identified by the opening size of the flat die, while the size is determined by the slicer under the flat die. When the biomass pellets come out in the shape of cylinders, the slicer under the flat die reduced them right into certain length. You can readjust the position of slicer to transform 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 equipment
Flat die pellet mill can be classified into roller-turned type and also die-turned type. The previous one has its flat die installed on the primary shaft. When the equipment works, the flat die turns and the roller maintain still. The later one has the press roller mounted on the primary shaft. The roller revolves with the major shaft, while the flat die maintain still.

Roller-turned kind embraces a lot more effective structure. It has bigger capacity and also even more sturdy transmission. However Die-turned kind is more tiny as well as mobile, with lower cost. Naturally, both of them have the ability to make top notch pellets.

Benefits and also weak point of flat die pellet equipment
Apartment die pellet mill has basic framework. It is little, light and also portable. The expense is much lower than ring die pellet equipment It is easy to operate and maintain. You can observe the pelletizing process and also resolve any fault in time. So it is prominent with farmers, home customers, and small fuel manufacturing plant.

The flat dies are putting on components, you require to change it on a regular basis. Yet it can be utilized with both sides. You can turn it over when one side has worn out. This way you can prolong their working life and reduce price.

On the other hand, the moving distance are various in the internal as well as external side of roller, which trigger the slide of rollers and abrasion on the flat die. Currently, several flat die pellet equipment adopt tapered roller to solve this trouble. TICO flat die pellet equipment embraces tapered roller and exceptional alloy steel in the flat die.

Besides, the get in touch with area of roller and also flat die is smaller sized than ring die pellet equipment, so the production ability and creating price is reduced.

Exactly how does a ring die pellet equipment job?
Framework of ring die pellet machine
A ring die pellet machine is composed of a screw feeder, conditioner, roller as well as ring die, release port, electrical motor, transmission, stand.

The ring die pellet equipment is driven by a direct-connected electric motor. The motor get in touch with the transmission through a shaft combining. The transmission bring along the main shaft, as well as the primary shaft bring along the rollers. So the roller began to rotate inside the ring die.

When you feed basic materials right into the ring die pellet machine via the hopper, they are transferred to the conditioner, where the raw materials are mixed with vapor or butter. The conditioning of the raw materials aims to enhance the glue pressure as well as developing rate.

After that, the processed basic materials will be transmitted to the pelletizing closet. Under the centrifugal force, they are distributed on the inner side of the ring die. The roller press the raw products right into the holes on the ring die. The heat and also high pressure cause physical as well as chemical adjustments to the raw products.



When they are squeezed out from the ring die, they become solid cylindrical sticks. The sticks expand longer, up until they are reduced by the slicer outside the ring die. Then the pellets fall down and also come out through the outlet.

2 types of ring die pellet machine
According to different positionings of the ring die, there are vertical ring die pellet equipment and also straight ring die pellet machine.

In the horizontal 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 kind, the ring die is put horizontally. The feed hopper is right above the ring die, and also the raw products comes under the ring die straight.

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

Advantages as well as weakness of ring die pellet equipment.
Ring die pellet mill includes high ability. The production per hour is from 800kg to 20t. As for flat die pellet machine, the ability is from 100kg/h to 1t/t. So if fish feed making machine low price manufacturing need is under 800kg, you would certainly much better select flat die pellet equipment, or ring die pellet equipment is preferable.

Due to the high production, the power usage each is reduced. The abrasion between roller as well as die is smaller. The operation and upkeep is easy. The pellets are consistent in dimension.
