How does a wood pellet machine work
How does a wood pellet machine job?
Generally, wood pellet equipment can be classified into flat die pellet machine and ring die pellet equipment.

Ring die pellet mill has large quantity and high capacity. It appropriates for factory usage and also massive manufacturing. Flat die pellet mill is little and portable. It has reduced capacity, ideal for home usage and small manufacturing. 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 made up of a feed receptacle, an upper closet, a discharge electrical outlet, a spindle box, gear box, a transmission shaft, an electric control cabinet, an electrical motor, a engine base, as well as 4 wheels, etc.

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

The core components: roller and 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 upper 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 flat die is made from superior alloy steel, whose firmness is 55-60 HRC.

There are many holes on the flat die, whose size is from 2.5 mm to 10mm, as well as 6mm, 8mm and 10mm are the most common types. They realize the very best compression proportion with a lot of experiments, appropriate for greater than 30 sort of products.

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

How does a flat die pellet machine work?
When gemco pellet machine price feed basic materials into the pellet equipment via the receptacle, they fall on the flat die and also spread over it under the feature of roller.

When you start the pellet machine, the electric motor runs and also bring along the main shaft with the gearbox. The press roller is mounted on the major shaft, so it rotates around the major shaft. Meanwhile, the rollers rotate around the roller shaft.

The revolving press kinds strong stress and also press the raw products into the holes on the flat die. The raw materials obtain built in these openings. When they are squeezed out, they become strong cylinders. At the same time, the strong rubbing in between roller and also die warm up the raw products to over 80 ° C, where the lignin as well as fibers get soft. They raise the sticky force of materials.

The diameter of the pellets is identified by the opening dimension of the flat die, while the size is figured out by the slicer under the flat die. When the biomass pellets appear in the form of cylinders, the slicer under the flat die cut them right into particular length. You can change the placement of slicer to alter the length.

After being cut by the slicers, the pellets fall down on the pellet-throwing tray. Under the function 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 kind and also die-turned kind. The former one has its flat die mounted on the primary shaft. When the machine functions, the flat die revolves and also the roller maintain still. The later one has the press roller mounted on the major shaft. The roller turns with the major shaft, while the flat die keep still.

Roller-turned type adopts more reliable framework. It has larger capability and even more resilient gearbox. However Die-turned kind is a lot more tiny and portable, with reduced cost. Of course, both of them have the ability to make top quality pellets.

Advantages and weak point of flat die pellet equipment

Apartment die pellet mill has simple framework. It is little, light and also portable. The cost is much less than ring die pellet machine It is very easy to run and also maintain. You can observe the pelletizing process and also address any type of mistake in time. So it is preferred with farmers, house individuals, and little gas production plant.

The flat dies are using components, you need to replace it regularly. But it can be made use of with both sides. You can turn it over when one side has broken. This way you can extend their functioning life and reduce expense.

On the other hand, the relocating distance are various in the inner and outer side of roller, which trigger the slide of rollers as well as abrasion on the flat die. Presently, hay pellet making machine embrace conical roller to fix this problem. TICO flat die pellet equipment adopts tapered roller and exceptional alloy steel in the flat die.

Besides, the call location of roller as well as flat die is smaller sized than ring die pellet equipment, so the production capability and also developing price is reduced.

How does horse feed pellet machine ?
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, electric motor, transmission, stand.

The ring die pellet machine is driven by a direct-connected motor. The electric motor connect with the transmission with a shaft combining. The transmission bring along the primary shaft, as well as the main shaft bring along the rollers. So the roller began to turn inside the ring die.

When you feed raw materials into the ring die pellet machine through the receptacle, they are transferred to the conditioner, where the raw products are mixed with vapor or butter. The conditioning of the raw materials aims to improve the sticky pressure and forming rate.

Then, the processed raw 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 high temperature and also high pressure reason physical and chemical adjustments to the raw products.

When they are squeezed out from the ring die, they come to be strong round sticks. The sticks expand longer, until they are reduced by the slicer outside the ring die. Then the pellets drop and appear with the outlet.

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

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

In the upright ring die pellet machine, both the roller as well as ring die turn. They create centrifugal force and distribute basic materials consistently. In the straight ring die pellet machine, only the ring die rotates. The raw materials are distributed in the ring die by the screw feeder.

Advantages and also weakness of ring die pellet machine.
Ring die pellet mill features high capability. The production per hour is from 800kg to 20t. When it comes to flat die pellet equipment, the capacity is from 100kg/h to 1t/t. So if you manufacturing need is under 800kg, you 'd better choose flat die pellet machine, or ring die pellet equipment is better.

Due to the high manufacturing, the power consumption each is reduced. The abrasion in between roller as well as die is smaller. The operation as well as maintenance is simple. The pellets are uniform in size.
