Just 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 machine.



Ring die pellet mill has large quantity and high ability. It appropriates for manufacturing facility usage as well as large production. Flat die pellet mill is small as well as mobile. It has reduced capacity, ideal for home usage as well as small-scale production. The rate of flat die pellet mill is much less than ring die pellet mill



Structure of flat die pellet mill.

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



The electric motor can be replaced by a diesel engine, fuel engine, or a PTO connector.




The core parts: roller and also flat die

The pelletizing part of the flat die pellet equipment is a press roller and 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 hardness is 55-60 HRC.



There are many holes on the flat die, whose diameter is from 2.5 mm to 10mm, and also 6mm, 8mm as well as 10mm are the most usual types. They understand the most effective compression proportion with a great deal of experiments, appropriate for more than 30 sort of products.



The clearance in between the roller and 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 readjust the clearance to adapt to different products.



Exactly how does a flat die pellet machine work?

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



When you start the pellet machine, the electric motor runs as well as bring along the major shaft with the transmission. The press roller is set up on the primary shaft, so it rotates around the main shaft. On the other hand, the rollers turn around the roller shaft.



The revolving press kinds solid stress and press the raw products into the holes on the flat die. The raw materials obtain built in these holes. When they are ejected, they come to be solid cyndrical tubes. On the other hand, the strong rubbing between roller and also die warm up the raw products to over 80 ° C, where the lignin as well as fibers obtain soft. richi pellet machine increase the glue force of products.



The size of the pellets is determined by the opening dimension of the flat die, while the size is identified by the slicer under the flat die. When the biomass pellets appear in the form of cyndrical tubes, the slicer under the flat die reduced them right into particular length. https://www.reddit.com/user/Carmen-Huang can change the placement 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 pressure, the pellets are sent though the discharge outlet.



2 kinds of flat die pellet equipment

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



Roller-turned type adopts more reliable structure. It has larger capacity and more durable transmission. But Die-turned type is more small as well as portable, with reduced price. Certainly, both of them are able to make high-grade pellets.



Benefits and also weak point of flat die pellet machine

Apartment die pellet mill has basic structure. It is tiny, light as well as mobile. The cost is a lot lower than ring die pellet equipment It is easy to run and keep. You can observe the pelletizing process as well as solve any fault in time. So it is prominent with farmers, residence users, and little gas production plant.



The flat dies are using parts, you need to change it on a regular basis. Yet it can be utilized with both sides. You can turn it over when one side has actually broken. This way you can prolong their functioning life and also decrease price.



On the other hand, the relocating range are different in the inner and also outer side of roller, which cause the slide of rollers and also abrasion on the flat die. Presently, numerous flat die pellet equipment embrace tapered roller to solve this problem. TICO flat die pellet equipment takes on tapered roller as well as remarkable alloy steel in the flat die.

Besides, the contact area of roller and flat die is smaller sized than ring die pellet equipment, so the manufacturing capability and developing rate is reduced.



Exactly how does a ring die pellet equipment work?

Structure of ring die pellet machine

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



The ring die pellet machine is driven by a direct-connected electric motor. The electric motor connect with the transmission through a shaft combining. The gearbox bring along the main shaft, as well as the major shaft bring along the rollers. So the roller started to revolve inside the ring die.



When you feed basic materials right into the ring die pellet equipment via the hopper, they are sent to the conditioner, where the raw materials are mixed with vapor or butter. The conditioning of the raw products aims to boost the adhesive force and also creating rate.



After that, the processed raw materials will be sent 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 right into the holes on the ring die. The heat and also high pressure cause physical and also chemical adjustments to the raw materials.



When they are squeezed out from the ring die, they come to be solid round sticks. The sticks expand much longer, up until they are reduced by the slicer outside the ring die. Then the pellets fall down and appear with the electrical outlet.



Two kinds of ring die pellet equipment

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



In the straight type, the ring die is positioned up and down. When resources fall down from the conditioner, they are fed right into the ring die flat by a forced feeder. In the upright kind, the ring die is put horizontally. The feed hopper is right above the ring die, as well as the raw materials falls into the ring die directly.



In the vertical ring die pellet equipment, both the roller and ring die turn. They form centrifugal pressure and also disperse resources uniformly. 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.



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

Ring die pellet mill features high capacity. The production per hr is from 800kg to 20t. As for flat die pellet equipment, the ability is from 100kg/h to 1t/t. So if you manufacturing need is under 800kg, you 'd much better select flat die pellet equipment, or ring die pellet machine is better.



Due to the high production, the power usage per unit is low. The abrasion between roller as well as die is smaller. The operation and also upkeep is simple. The pellets are consistent in size.
