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



Ring die pellet mill has huge volume as well as high capability. It is suitable for manufacturing facility usage and large manufacturing. Apartment die pellet mill is tiny and portable. It has lower capacity, suitable for house use and also small production. The rate of flat die pellet mill is a lot less than ring die pellet mill



Framework of flat die pellet mill.

From top to bottom, a flat die pellet mill is made up of a feed hopper, a top closet, a discharge electrical outlet, a spindle box, gear box, a transmission shaft, an electric control cupboard, an electrical motor, a engine base, and also 4 wheels, and so on.



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



The core components: roller as well as 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 set up on the 2 ends of the roller shaft. The rollers have grooves on the surface area. The roller and flat die is constructed from superior alloy steel, whose solidity 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 the most common types. They realize the very best compression proportion with a great deal of experiments, ideal for greater than 30 kinds of materials.



The clearance in between the roller and also 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 various products.



Exactly 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 spread over it under the feature of roller.



When you begin the pellet equipment, the electrical motor runs as well as bring along the major shaft via the transmission. Journalism roller is installed on the main shaft, so it rotates around the major shaft. On the other hand, the rollers revolve around the roller shaft.



The turning press forms solid pressure and press the raw products right into the holes on the flat die. The raw products obtain built in these holes. When they are ejected, they end up being strong cylinders. On the other hand, the strong rubbing in between roller and die heat up the raw products to over 80 ° C, where the lignin and fibers obtain soft. They increase the glue pressure of materials.



The diameter of the pellets is identified by the opening dimension of the flat die, while the length is identified by the slicer under the flat die. When the biomass pellets come out in the form of cyndrical tubes, the slicer under the flat die reduced them right into particular length. You can change 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 though the discharge outlet.



2 kinds of flat die pellet equipment

Flat die pellet mill can be classified into roller-turned kind and die-turned kind. The previous one has its flat die mounted on the major shaft. When the machine works, the flat die turns and the roller maintain still. The later one has the press roller mounted on the major shaft. The roller rotates with the primary shaft, while the flat die maintain still.



Roller-turned type adopts much more reliable framework. It has larger capability as well as even more resilient transmission. But richi pellet machine -turned kind is much more tiny as well as mobile, with lower price. Naturally, both of them are able to make premium pellets.



Advantages as well as weakness of flat die pellet machine

Flat die pellet mill has simple framework. It is little, light and mobile. The cost is a lot lower than ring die pellet machine It is very easy to run and maintain. You can observe the pelletizing procedure as well as address any fault in time. So it is prominent with farmers, home users, and little fuel production plant.



The flat dies are using parts, you need to change it consistently. But it can be utilized with both sides. You can transform it over when one side has worn out. This way you can prolong their functioning life and decrease price.



On the other hand, the moving range are various in the inner and outer side of roller, which cause the slide of rollers as well as abrasion on the flat die. Currently, several flat die pellet machine take on conical roller to resolve this problem. TICO flat die pellet equipment embraces tapered roller as well as remarkable alloy steel in the flat die.

Besides, the call area of roller and flat die is smaller than ring die pellet machine, so the production capacity and also developing rate is lower.



How does a ring die pellet equipment work?

Structure of ring die pellet machine

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



The ring die pellet equipment is driven by a direct-connected motor. The electric motor get in touch with the gearbox via a shaft coupling. The transmission bring along the major shaft, and the primary shaft bring along the rollers. So the roller began to revolve inside the ring die.



When you feed raw materials into the ring die pellet equipment via the hopper, they are transferred to the conditioner, where the raw materials are blended with vapor or butter. The conditioning of the raw materials aims to improve the glue force and creating price.



Then, the processed raw materials will certainly be transferred to the pelletizing cabinet. Under the centrifugal force, they are dispersed on the inner side of the ring die. The roller press the raw materials right into the holes on the ring die. The high temperature as well as high pressure cause physical as well as chemical modifications to the raw materials.



When they are ejected from the ring die, they become solid round sticks. The sticks grow longer, until they are reduced by the slicer outside the ring die. Then click to find out more drop and also appear through the electrical outlet.



Two types of ring die pellet machine

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




In the straight type, the ring die is put vertically. When raw materials drop from the conditioner, they are fed into the ring die flat by a forced feeder. In the vertical type, the ring die is put flat. The feed hopper is right above the ring die, as well as the raw materials comes under the ring die straight.



In the upright ring die pellet machine, both the roller as well as ring die revolve. richi pellet mill create centrifugal pressure as well as distribute resources evenly. In the horizontal ring die pellet machine, 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 ability. 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 production requirement is under 800kg, you 'd better pick flat die pellet machine, or ring die pellet equipment is better.



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