How does a wood pellet equipment job?<br>
Usually, wood pellet equipment can be classified into flat die pellet equipment as well as ring die pellet equipment.



Ring die pellet mill has large quantity and high capability. It appropriates for manufacturing facility use as well as large-scale manufacturing. Apartment die pellet mill is little as well as portable. It has lower capability, suitable for residence use and small manufacturing. The rate of flat die pellet mill is much lower than ring die pellet mill



Framework of flat die pellet mill.

Inside out, a flat die pellet mill is composed of a feed receptacle, a top cabinet, a discharge outlet, a pin box, transmission, a transmission shaft, an electrical control closet, an electric motor, a engine base, and 4 wheels, etc.



The electrical motor can be changed by a diesel engine, gasoline engine, or a PTO adapter.



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 mounted in the upper cupboard. 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 made of exceptional alloy steel, whose firmness is 55-60 HRC.



There are lots of holes on the flat die, whose diameter is from 2.5 mm to 10mm, as well as 6mm, 8mm and 10mm are one of the most usual types. They understand the best compression ratio with a lot of experiments, ideal for more than 30 type of products.



The clearance in between the roller and also flat die is 0.1-0.3 mm. This is where the raw product layer kinds. There are 2 changing 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 work?

When you feed resources right into the pellet machine via the receptacle, 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 major shaft via the gearbox. floating fish feed pellet making machine is installed on the main shaft, so it revolves around the major shaft. At the same time, the rollers revolve around the roller shaft.



The turning press forms strong stress and press the raw materials into the holes on the flat die. The raw materials get formed in these holes. When they are ejected, they come to be strong cyndrical tubes. On the other hand, the strong rubbing in between roller and also die warm up the raw products to over 80 ° C, where the lignin and fibers obtain soft. They increase the adhesive force of materials.




The size of the pellets is determined by the hole size of the flat die, while the length is established by the slicer under the flat die. When the biomass pellets appear in the shape of cyndrical tubes, the slicer under the flat die reduced them into certain length. You can change the placement of slicer to change the size.



After being cut by the slicers, the pellets fall down on the pellet-throwing tray. Under the function of centrifugal pressure, the pellets are sent out though the discharge electrical outlet.



2 sorts of flat die pellet machine

Apartment die pellet mill can be classified into roller-turned kind and die-turned kind. The former one has its flat die set up on the main shaft. When the equipment functions, the flat die turns and also the roller keep still. The later one has the press roller set up on the major shaft. The roller revolves with the primary shaft, while the flat die keep still.



Roller-turned type embraces more efficient framework. It has larger ability as well as more long lasting gearbox. Yet Die-turned type is extra small as well as portable, with lower cost. Certainly, both of them have the ability to make high-grade pellets.



Advantages and also weakness of flat die pellet equipment

Flat die pellet mill has straightforward framework. It is little, light as well as portable. The price is much lower than ring die pellet machine It is very easy to operate and also preserve. You can observe the pelletizing process and resolve any type of mistake in time. So it is popular with farmers, home individuals, and small fuel production plant.



The flat dies are wearing components, you require to change it on a regular basis. But it can be utilized with both sides. You can transform it over when one side has broken. This way you can prolong their functioning life as well as minimize cost.



On the other hand, the moving distance are different in the inner as well as outer side of roller, which create the slide of rollers and abrasion on the flat die. Presently, numerous flat die pellet machine take on conical roller to resolve this trouble. TICO flat die pellet machine takes on tapered roller as well as superior alloy steel in the flat die.

Besides, the get in touch with area of roller as well as flat die is smaller than ring die pellet machine, so the manufacturing capacity and forming price is lower.



Exactly how does a ring die pellet equipment job?

Structure of ring die pellet machine

A ring die pellet machine is made up of a screw feeder, conditioner, roller and ring die, release port, electrical motor, transmission, pedestal.



The ring die pellet equipment is driven by a direct-connected electric motor. The electric motor connect with the transmission via 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 revolve inside the ring die.



When you feed raw materials right into the ring die pellet equipment with the receptacle, they are transmitted to the conditioner, where the raw products are blended with vapor or butter. The conditioning of the raw products intends to improve the sticky force and forming rate.



After that, the refined raw materials will be transmitted to the pelletizing cabinet. Under the centrifugal force, they are dispersed on the internal side of the ring die. The roller press the raw materials right into the holes on the ring die. The heat and high pressure cause physical as well as chemical changes to the raw materials.



When they are squeezed out 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. After that the pellets fall down and come out with the outlet.



Two 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 machine.



In the horizontal type, the ring die is put up and down. When basic materials fall down from the conditioner, they are fed right into the ring die flat by a forced feeder. In the upright type, the ring die is put horizontally. The feed receptacle is right over the ring die, as well as the raw products falls under the ring die directly.



In the vertical ring die pellet machine, both the roller and also ring die rotate. They develop centrifugal force as well as distribute raw materials consistently. In the straight ring die pellet equipment, just the ring die rotates. bio pellet machine are dispersed in the ring die by the screw feeder.



Advantages as well as weak point of ring die pellet equipment.

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



As a result of the high production, the power consumption each is reduced. The abrasion between roller and also die is smaller sized. The operation and also maintenance is very easy. The pellets are consistent in size.
