How does a wood pellet machine work?<br>
Typically, wood pellet equipment can be classified into flat die pellet equipment and also ring die pellet equipment.



Ring die pellet mill has big volume and high capacity. It is suitable for factory usage as well as massive manufacturing. Apartment die pellet mill is little as well as portable. It has lower capacity, ideal for house usage as well as small-scale 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 made up of a feed receptacle, an upper cupboard, a discharge outlet, a pin box, transmission, a transmission shaft, an electrical control cupboard, an electrical motor, a engine base, and 4 wheels, etc.



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



The core parts: roller as well as flat die

The pelletizing part of the flat die pellet equipment is a press roller and also a flat die. They are set up in the upper cabinet. There are 2-4 rollers installed on the 2 ends of the roller shaft. The rollers have grooves on the surface. The roller and flat die is constructed from exceptional 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 as well as 10mm are the most typical types. They understand the best compression proportion with a large number of experiments, suitable for more than 30 kinds of materials.



The clearance between the roller and also flat die is 0.1-0.3 mm. This is where the raw product layer forms. There are richi pellet mill readjusting nuts on the side of the pellet mill, you can change the clearance to adapt to different materials.



Exactly how does a flat die pellet machine work?

When you feed raw materials right into the pellet machine via the hopper, they fall on the flat die as well as spread over it under the function of roller.



When you start the pellet equipment, the electric motor runs and bring along the main shaft through the gearbox. Journalism roller is installed on the main shaft, so it rotates around the primary shaft. Meanwhile, the rollers revolve around the roller shaft.



The revolving press types strong pressure as well as press the raw products into the holes on the flat die. The raw materials get molded in these openings. When they are ejected, they come to be solid cyndrical tubes. On the other hand, the solid friction between roller as well as die heat up the raw products to over 80 ° C, where the lignin as well as fibers obtain soft. They enhance the glue force of products.



The diameter of the pellets is established by the hole size of the flat die, while the size 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 cut them into particular size. You can change the position of slicer to change the length.



After being reduced by the slicers, the pellets fall down on the pellet-throwing tray. Under the feature 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 as well as die-turned type. The former one has its flat die set up on the main shaft. When the equipment works, the flat die rotates and the roller maintain still. The later one has journalism roller mounted on the major shaft. The roller revolves with the major shaft, while the flat die keep still.



Roller-turned kind embraces extra effective structure. It has larger capacity and also even more long lasting transmission. But Die-turned type is extra small as well as portable, with reduced cost. Certainly, both of them are able to make top notch pellets.



Benefits and weak point of flat die pellet equipment

Apartment die pellet mill has easy structure. It is tiny, light as well as portable. The cost is much lower than ring die pellet equipment It is simple to operate and preserve. You can observe the pelletizing process and address any mistake in time. So it is preferred with farmers, house individuals, as well as small fuel production plant.



The flat dies are wearing components, you need to replace it routinely. Yet it can be used with both sides. You can turn it over when one side has actually worn out. In this way you can extend their working life and lower expense.



On the other hand, the relocating distance are various in the inner as well as outer side of roller, which create the slide of rollers and abrasion on the flat die. Currently, lots of flat die pellet machine take on tapered roller to address this problem. TICO flat die pellet machine adopts tapered roller and premium alloy steel in the flat die.

Besides, the contact location of roller as well as flat die is smaller sized than ring die pellet equipment, so the production capacity and creating rate is reduced.




Exactly how does a ring die pellet equipment work?


Structure of ring die pellet machine

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



The ring die pellet machine is driven by a direct-connected motor. The electric motor get in touch with the transmission via a shaft combining. The gearbox bring along the main shaft, and also the major shaft bring along the rollers. So the roller started to rotate inside the ring die.



When you feed raw materials into the ring die pellet equipment through the hopper, they are sent to the conditioner, where the raw products are blended with vapor or butter. The conditioning of the raw products intends to enhance the sticky pressure and creating price.



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



When they are squeezed out from the ring die, they come to be solid cylindrical sticks. The sticks expand longer, until they are reduced by the slicer outside the ring die. Then the pellets drop and also come out through the electrical outlet.



Two kinds of ring die pellet equipment

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



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



In the upright ring die pellet equipment, both the roller as well as ring die rotate. They develop centrifugal pressure and also distribute raw materials consistently. In the straight ring die pellet machine, just the ring die rotates. The raw products are distributed in the ring die by the screw feeder.



Benefits and weak point of ring die pellet equipment.

Ring die pellet mill features high ability. alfalfa pellet mill for sale manufacturing per hour is from 800kg to 20t. As for flat die pellet machine, the capability is from 100kg/h to 1t/t. So if you production requirement is under 800kg, you 'd better select flat die pellet machine, or ring die pellet machine is better.



Because of the high manufacturing, the power usage each is low. The abrasion in between roller and also die is smaller. The procedure and also upkeep is easy. The pellets are consistent in dimension.
