Exactly how does a wood pellet machine job?<br>
Generally, wood pellet machine can be classified right into flat die pellet equipment as well as ring die pellet machine.



Ring die pellet mill has big quantity and high capacity. Richi machine appropriates for factory use as well as massive manufacturing. Apartment die pellet mill is little as well as mobile. It has reduced capability, ideal for residence use and also small manufacturing. The cost of flat die pellet mill is a lot 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 hopper, an upper cabinet, a discharge outlet, a pin box, transmission, a transmission shaft, an electric control cupboard, an electrical motor, a engine base, and also 4 wheels, etc.



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



The core parts: roller as well as flat die

The pelletizing part of the flat die pellet machine is a press roller as well as a flat die. They are set up 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. The roller as well as flat die is constructed from superior alloy steel, whose hardness is 55-60 HRC.



There are lots of holes on the flat die, whose diameter is from 2.5 mm to 10mm, and also 6mm, 8mm and 10mm are one of the most usual types. They realize the most effective compression ratio with a large number of experiments, appropriate for more than 30 kinds of materials.



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



How does a flat die pellet equipment job?

When you feed resources right into the pellet equipment via the hopper, they fall on the flat die and also spread over it under the function of roller.



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



The rotating press types strong pressure and press the raw products right into the holes on the flat die. The raw products obtain molded in these openings. When they are squeezed out, they become solid cylinders. Meanwhile, the strong friction between roller as well as die heat up the raw materials to over 80 ° C, where the lignin as well as fibers get soft. They boost the adhesive pressure of materials.



The size of the pellets is determined by the hole size of the flat die, while the size is determined by the slicer under the flat die. When gemco pellet machine price appear in the form of cyndrical tubes, the slicer under the flat die cut them into particular size. You can adjust the placement of slicer to change 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 electrical outlet.



2 types of flat die pellet equipment

Flat die pellet mill can be classified right into roller-turned kind and also die-turned kind. The previous one has its flat die set up on the primary shaft. When the machine works, the flat die rotates as well as the roller keep still. The later one has journalism roller installed on the main shaft. look these up turns with the primary shaft, while the flat die maintain still.



Roller-turned kind embraces a lot more reliable structure. It has bigger capability and more durable transmission. Yet Die-turned kind is a lot more little as well as mobile, with reduced price. Obviously, both of them are able to make high-grade pellets.



Advantages and weak point of flat die pellet equipment

Flat die pellet mill has basic structure. It is tiny, light as well as portable. The price is much lower than ring die pellet machine It is simple to run as well as maintain. You can observe the pelletizing procedure as well as address any kind of fault in time. So it is popular with farmers, house customers, as well as small fuel manufacturing plant.



The flat dies are using parts, you require to change it consistently. However it can be used with both sides. You can turn it over when one side has broken. By doing this you can prolong their working life and also minimize price.



On the other hand, the moving distance are different in the internal as well as external side of roller, which create the slide of rollers as well as abrasion on the flat die. Currently, lots of flat die pellet machine take on conical roller to fix this trouble. TICO flat die pellet equipment adopts conical roller and also superior alloy steel in the flat die.

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



How does a ring die pellet equipment job?

Framework of ring die pellet equipment

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




The ring die pellet equipment is driven by a direct-connected motor. The motor connect with the gearbox via a shaft combining. The transmission bring along the primary shaft, and also the primary shaft bring along the rollers. So the roller started to revolve inside the ring die.



When you feed raw materials into the ring die pellet equipment with the receptacle, they are sent to the conditioner, where the raw products are combined with vapor or butter. The conditioning of the raw products intends to improve the adhesive force as well as creating price.



After that, the refined raw materials will be transferred to the pelletizing closet. Under the centrifugal force, they are distributed on the internal side of the ring die. The roller press the raw products right into the holes on the ring die. The high temperature as well as high pressure reason physical and also chemical modifications to the raw materials.



When they are squeezed out from the ring die, they come to be strong cylindrical sticks. The sticks grow longer, until they are reduced by the slicer outside the ring die. After that the pellets drop and appear via the electrical outlet.



2 types of ring die pellet equipment

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



In the horizontal kind, the ring die is positioned vertically. When resources drop from the conditioner, they are fed into the ring die horizontally by a forced feeder. In the upright type, the ring die is put flat. The feed receptacle is right over the ring die, and also the raw materials falls into the ring die directly.



In the vertical ring die pellet machine, both the roller as well as ring die rotate. They form centrifugal force as well as distribute basic materials uniformly. In the straight ring die pellet equipment, just the ring die rotates. The raw products are distributed in the ring die by the screw feeder.



Advantages and also weak point of ring die pellet machine.

Ring die pellet mill features high ability. The manufacturing per hr is from 800kg to 20t. When it comes to flat die pellet equipment, the ability is from 100kg/h to 1t/t. So if you manufacturing demand is under 800kg, you would certainly better pick flat die pellet machine, or ring die pellet machine is preferable.



Due to the high production, the power usage each is reduced. The abrasion in between roller as well as die is smaller sized. The procedure and also upkeep is easy. The pellets are uniform in size.
