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




Ring die pellet mill has big volume as well as high capability. It appropriates for factory use and also large-scale production. Apartment die pellet mill is small and mobile. It has reduced capability, suitable for home use and also small production. The cost of flat die pellet mill is a lot lower than ring die pellet mill



Framework of flat die pellet mill.

Inside out, a flat die pellet mill is made up of a feed hopper, an upper cupboard, a discharge electrical outlet, a pin box, gear box, a transmission shaft, an electrical control closet, an electrical motor, a engine base, and 4 wheels, etc.



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



The core parts: roller and also flat die

The pelletizing part of the flat die pellet equipment is a press roller as well as a flat die. They are set up in the upper closet. There are 2-4 rollers set up on the 2 ends of the roller shaft. The rollers have grooves on the surface. The roller and flat die is constructed from premium alloy steel, whose hardness is 55-60 HRC.



There are many openings on the flat die, whose size is from 2.5 mm to 10mm, and also 6mm, 8mm and 10mm are one of the most usual kinds. They realize the most effective compression ratio with a lot of experiments, suitable for greater than 30 type of products.



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



How does a flat die pellet equipment 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 start the pellet equipment, the electric motor runs and bring along the primary shaft with the transmission. Journalism roller is set up on the primary shaft, so it rotates around the primary shaft. Meanwhile, the rollers turn around the roller shaft.



The turning press kinds strong pressure as well as press the raw products right into the holes on the flat die. The raw products get built in these holes. When they are ejected, they come to be strong cyndrical tubes. On the other hand, the strong friction between roller and also die heat up the raw materials to over 80 ° C, where the lignin and also fibers obtain soft. They enhance the adhesive force of materials.



The diameter of the pellets is established by the hole dimension of the flat die, while the size is identified by the slicer under the flat die. When the biomass pellets come out in the shape of cyndrical tubes, the slicer under the flat die reduced them into specific size. You can change the position 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 though the discharge electrical outlet.



Two kinds of flat die pellet equipment

Flat die pellet mill can be classified into roller-turned type as well as die-turned type. The previous one has its flat die mounted on the primary shaft. When the machine functions, the flat die revolves and also the roller maintain still. The later one has the press roller installed on the main shaft. The roller rotates with the major shaft, while the flat die keep still.



Roller-turned kind embraces a lot more effective framework. It has bigger ability and more sturdy transmission. But Die-turned kind is a lot more little as well as mobile, with reduced cost. Obviously, both of them are able to make premium pellets.



Benefits as well as weakness of flat die pellet machine

Flat die pellet mill has straightforward structure. It is little, light and portable. The expense is much less than ring die pellet machine It is very easy to run and also preserve. You can observe the pelletizing process and resolve any type of fault in time. So sheep feed pellet machine is preferred with farmers, home individuals, and also tiny gas manufacturing plant.



The flat dies are wearing components, you need to change it consistently. But it can be made use of with both sides. You can transform it over when one side has actually worn out. By doing this you can extend their working life and also minimize expense.



On the other hand, the relocating range are different in the inner and also outer side of roller, which trigger the slide of rollers as well as abrasion on the flat die. Presently, mini fish feed making machine take on conical roller to fix this issue. TICO flat die pellet machine adopts conical roller and remarkable alloy steel in the flat die.

Besides, the contact location of roller as well as flat die is smaller than ring die pellet machine, so the manufacturing capacity as well as forming rate is lower.



Just how does a ring die pellet machine 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, release port, electrical motor, transmission, stand.



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



When you feed raw materials right into the ring die pellet equipment with the receptacle, they are sent to the conditioner, where the raw materials are combined with vapor or butter. The conditioning of the raw materials intends to enhance the glue force as well as forming rate.



Then, the processed resources will certainly be sent to the pelletizing cabinet. Under the centrifugal force, they are distributed on the inner side of the ring die. The roller press the raw products into the holes on the ring die. The high temperature and also high pressure cause physical as well as chemical changes to the raw products.



When they are squeezed out from the ring die, they end up being solid round sticks. The sticks expand much longer, up until they are reduced by the slicer outside the ring die. After that the pellets drop and appear via the outlet.



2 types of ring die pellet equipment

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



In the horizontal kind, the ring die is placed vertically. When basic materials fall down from the conditioner, they are fed right into the ring die flat by a forced feeder. In the vertical kind, the ring die is positioned flat. The feed receptacle is right above the ring die, and the raw materials falls into the ring die straight.



In the vertical ring die pellet machine, both the roller as well as ring die turn. They create centrifugal pressure and disperse basic materials evenly. In the horizontal ring die pellet equipment, just the ring die rotates. The raw materials are distributed in the ring die by the screw feeder.



Benefits and also weak point 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 capability is from 100kg/h to 1t/t. So if you manufacturing requirement is under 800kg, you would certainly much better pick flat die pellet machine, or ring die pellet machine is more suitable.



As a result of the high manufacturing, the power usage each is low. The abrasion in between roller as well as die is smaller sized. The procedure and upkeep is easy. The pellets are consistent in size.
