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



Ring die pellet mill has large volume as well as high capability. It appropriates for factory use and massive manufacturing. Flat die pellet mill is little and mobile. It has lower ability, suitable for house usage and small manufacturing. The price 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 composed of a feed receptacle, an upper closet, a discharge electrical outlet, a spindle box, transmission, a transmission shaft, an electrical control cupboard, an electrical motor, a engine base, and also 4 wheels, and so on.



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



The core parts: roller and flat die

The pelletizing part of the flat die pellet machine is a press roller as well as a flat die. They are installed in the upper cupboard. There are 2-4 rollers set up 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 remarkable alloy steel, whose firmness is 55-60 HRC.



There are several openings on the flat die, whose diameter is from 2.5 mm to 10mm, as well as 6mm, 8mm and also 10mm are one of the most common kinds. They understand the most effective compression ratio with a lot of experiments, appropriate for more than 30 kinds of products.



The clearance in between the roller and also flat die is 0.1-0.3 mm. This is where the raw material layer forms. There are 2 readjusting nuts on the side of the pellet mill, you can change the clearance to adapt to various products.



Exactly how does a flat die pellet machine work?

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



When you start the pellet equipment, the electric motor runs and also bring along the main shaft with the transmission. Journalism roller is installed on the main shaft, so it revolves around the major shaft. On the other hand, the rollers turn around the roller shaft.



The revolving press forms solid pressure and press the raw materials into the holes on the flat die. The raw products get formed in these openings. When they are ejected, they become strong cyndrical tubes. On the other hand, the strong rubbing between roller and also die heat up the raw products to over 80 ° C, where the lignin and also fibers get soft. They enhance the sticky pressure of products.



The size of the pellets is figured out by the hole dimension of the flat die, while the length is determined by the slicer under the flat die. When the biomass pellets come out in the form of cylinders, the slicer under the flat die cut them into specific length. You can change the position of slicer to transform the length.



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 machine

Apartment die pellet mill can be classified into roller-turned type and die-turned type. The former one has its flat die installed on the major shaft. When the machine functions, the flat die revolves and the roller maintain still. The later one has journalism roller installed on the main shaft. The roller revolves with the major shaft, while the flat die maintain still.



Roller-turned type takes on more reliable framework. It has bigger capability and also more sturdy transmission. Yet Die-turned type is more small as well as portable, with reduced cost. Certainly, both of them have the ability to make top notch pellets.



Advantages and also weakness of flat die pellet machine

Apartment die pellet mill has straightforward framework. It is small, light and mobile. The cost is much less than ring die pellet equipment It is simple to operate and also preserve. You can observe the pelletizing procedure and resolve any kind of fault in time. So it is popular with farmers, residence individuals, and also little fuel manufacturing plant.



The flat dies are using components, you require to replace it frequently. But it can be made use of with both sides. You can turn it over when one side has actually broken. In this way you can extend their functioning life and also lower cost.




On the other hand, the moving range are different in the internal as well as external side of roller, which create the slide of rollers and abrasion on the flat die. Presently, numerous flat die pellet equipment embrace tapered roller to solve this issue. richi pellet adopts conical roller and also remarkable alloy steel in the flat die.

Besides, the call area of roller and also flat die is smaller than ring die pellet equipment, so the manufacturing ability as well as forming price is reduced.



How does a ring die pellet machine job?

Framework of ring die pellet machine

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



The ring die pellet equipment is driven by a direct-connected motor. chicken feed pellet machine connect with the gearbox through a shaft coupling. The gearbox bring along the major shaft, and also the major shaft bring along the rollers. So the roller started to revolve inside the ring die.



When you feed basic materials into the ring die pellet equipment with the receptacle, they are transmitted to the conditioner, where the raw materials are mixed with vapor or butter. The conditioning of the raw materials intends to enhance the glue pressure and also developing price.



After that, the processed basic materials will certainly be transferred to the pelletizing cabinet. Under the centrifugal force, they are dispersed 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 and also high pressure cause physical and also chemical modifications to the raw materials.



When they are ejected from the ring die, they come to be strong round sticks. The sticks grow much longer, till they are reduced by the slicer outside the ring die. Then the pellets drop and also appear via the outlet.



Two sorts of ring die pellet machine

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



In the straight type, the ring die is placed up and down. When raw materials fall down from the conditioner, they are fed into the ring die flat by a forced feeder. In the vertical type, the ring die is placed flat. The feed receptacle is right over the ring die, and the raw products falls under the ring die directly.



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



Benefits as well as weakness of ring die pellet equipment.

Ring die pellet mill features high capability. The manufacturing per hr 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 demand is under 800kg, you 'd much better choose flat die pellet equipment, or ring die pellet equipment is more suitable.



Due to the high manufacturing, the power intake each is reduced. The abrasion between roller as well as die is smaller sized. The procedure and also maintenance is very easy. The pellets are consistent in size.
