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



Ring die pellet mill has large quantity and also high ability. It appropriates for manufacturing facility usage and large manufacturing. Apartment die pellet mill is little as well as mobile. It has lower ability, appropriate for residence use and small-scale production. The cost of flat die pellet mill is a lot less 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, a top cupboard, a discharge outlet, a pin box, gear box, a transmission shaft, an electrical control closet, an electrical motor, a engine base, and 4 wheels, and so on.



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



The core components: roller as well as flat die

The pelletizing part of the flat die pellet machine is a press roller and a flat die. They are set up in the upper cupboard. There are 2-4 rollers mounted on the 2 ends of the roller shaft. The rollers have grooves on the surface. The roller and also flat die is made from exceptional alloy steel, whose solidity is 55-60 HRC.



There are several openings on the flat die, whose diameter is from 2.5 mm to 10mm, and 6mm, 8mm as well as 10mm are the most typical types. They understand the most effective compression ratio with a great deal of experiments, appropriate for greater than 30 type of materials.



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




How does a flat die pellet machine job?

When you feed basic materials right into the pellet equipment with the hopper, they fall on the flat die and also spread over it under the feature of roller.



When you start the pellet machine, the electric motor runs as well as bring along the major shaft via the gearbox. https://wakelet.com/wake/dpoAaAXIYAqMZArZP41jT is mounted on the main shaft, so it revolves around the major shaft. On the other hand, the rollers revolve around the roller shaft.



The turning press forms solid stress as well as press the raw materials right into the holes on the flat die. The raw products obtain built in these holes. When they are squeezed out, they end up being strong cylinders. On the other hand, the solid friction between roller and die warm up the raw products to over 80 ° C, where the lignin and fibers get soft. They increase the sticky force of products.



The size of the pellets is determined by the hole dimension of the flat die, while the length is figured out by the slicer under the flat die. When the biomass pellets come out in the shape of cylinders, the slicer under the flat die reduced them right into certain length. You can change the setting of slicer to alter 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 outlet.



Two kinds of flat die pellet machine

Flat die pellet mill can be classified into roller-turned kind 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 rotates and also the roller keep still. The later one has the press roller installed on the main shaft. The roller revolves with the main shaft, while the flat die maintain still.



Roller-turned kind takes on a lot more efficient structure. It has bigger capability as well as even more durable transmission. Yet richi machinery -turned type is extra little as well as mobile, with reduced expense. Naturally, both of them have the ability to make high-quality pellets.



Benefits and weakness of flat die pellet equipment

Flat die pellet mill has easy structure. It is small, light and also mobile. The expense is a lot lower than ring die pellet equipment It is easy to run as well as keep. You can observe the pelletizing procedure as well as resolve any kind of mistake in time. So it is prominent with farmers, residence customers, as well as tiny gas manufacturing plant.



The flat dies are putting on components, you require to change it regularly. However it can be utilized with both sides. You can turn it over when one side has worn out. In this way you can extend their working life and decrease price.



On the other hand, the moving range are various in the internal and external side of roller, which create the slide of rollers and abrasion on the flat die. Presently, lots of flat die pellet machine adopt conical roller to resolve this trouble. TICO flat die pellet machine embraces conical roller and also exceptional alloy steel in the flat die.

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



How does a ring die pellet machine work?

Framework of ring die pellet equipment

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



The ring die pellet equipment is driven by a direct-connected motor. The electric motor get in touch with the transmission with a shaft coupling. The gearbox bring along the major shaft, as well as the primary shaft bring along the rollers. So the roller began to revolve inside the ring die.



When you feed raw materials into the ring die pellet machine with the receptacle, they are transmitted to the conditioner, where the raw materials are combined with vapor or butter. The conditioning of the raw materials aims to improve the glue force and developing price.



After that, the refined resources will be transferred to the pelletizing closet. Under the centrifugal pressure, they are dispersed on the internal side of the ring die. The roller press the raw products into the holes on the ring die. The heat and high pressure cause physical and also chemical adjustments to the raw products.



When they are ejected from the ring die, they become strong cylindrical sticks. The sticks expand much longer, till they are cut by the slicer outside the ring die. After that the pellets drop and also come out via the outlet.



Two sorts of ring die pellet machine

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



In the horizontal type, the ring die is placed vertically. When raw materials drop from the conditioner, they are fed right into the ring die horizontally by a forced feeder. In the vertical type, the ring die is positioned horizontally. The feed receptacle is right above the ring die, and also the raw materials comes under the ring die directly.



In the upright ring die pellet equipment, both the roller as well as ring die turn. They develop centrifugal pressure and also distribute resources 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.



Benefits and also weak point of ring die pellet machine.

Ring die pellet mill features high capability. The production per hr is from 800kg to 20t. As for flat die pellet machine, the ability is from 100kg/h to 1t/t. So if you manufacturing demand is under 800kg, you would certainly much 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 sized. The procedure and upkeep is very easy. The pellets are uniform in dimension.
