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



Ring die pellet mill has big volume and also high capacity. It is suitable for manufacturing facility usage and large manufacturing. Apartment die pellet mill is little and portable. It has lower capacity, appropriate for home usage as well as small manufacturing. The price of flat die pellet mill is much less than ring die pellet mill



Structure of flat die pellet mill.

From top to bottom, 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 electric motor, a engine base, and also 4 wheels, and so on.



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



The core parts: roller and also 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 cabinet. There are over at this website -4 rollers set up on the 2 ends of the roller shaft. The rollers have grooves on the surface area. The roller and flat die is made from remarkable alloy steel, whose hardness is 55-60 HRC.



There are several holes on the flat die, whose size is from 2.5 mm to 10mm, as well as 6mm, 8mm as well as 10mm are the most typical kinds. They recognize the most effective compression ratio with a large number of experiments, appropriate 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 types. There are 2 readjusting nuts on the side of the pellet mill, you can readjust the clearance to adapt to various materials.



Exactly how does a flat die pellet machine job?

When you feed basic materials into the pellet machine through the receptacle, they fall on the flat die as well as spread over it under the function of roller.




When you begin the pellet equipment, the electrical motor runs as well as bring along the main shaft through the transmission. The press roller is mounted on the major shaft, so it turns around the main shaft. At the same time, the rollers rotate around the roller shaft.



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



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



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 types of flat die pellet machine

Apartment die pellet mill can be classified into roller-turned type and die-turned kind. homemade pellet mill plans has its flat die installed on the main shaft. When the machine works, the flat die revolves and the roller maintain still. The later one has the press roller set up on the primary shaft. The roller turns with the primary shaft, while the flat die maintain still.



Roller-turned kind adopts much more efficient framework. It has bigger ability and even more resilient transmission. But Die-turned type is more little as well as portable, with lower cost. Of course, both of them are able to make premium pellets.



Advantages and also weakness of flat die pellet machine

Flat die pellet mill has simple framework. It is small, light and also mobile. The cost is a lot lower than ring die pellet equipment It is easy to operate and preserve. You can observe the pelletizing procedure and fix any type of fault in time. So it is prominent with farmers, house customers, and tiny gas manufacturing plant.



The flat dies are using parts, you require to change it frequently. But it can be used with both sides. You can transform it over when one side has worn out. In this way you can expand their working life and also reduce cost.



On the other hand, the moving range are different in the inner and outer side of roller, which create the slide of rollers and also abrasion on the flat die. Currently, several flat die pellet machine take on conical roller to fix this issue. TICO flat die pellet machine takes on conical roller as well as remarkable alloy steel in the flat die.

Besides, the contact area of roller and flat die is smaller than ring die pellet equipment, so the production ability and creating rate is lower.



Just how does a ring die pellet equipment job?


Structure of ring die pellet equipment

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



The ring die pellet machine is driven by a direct-connected electric motor. small floating fish feed machine connect with the gearbox through a shaft combining. The gearbox bring along the primary shaft, as well as the primary shaft bring along the rollers. So the roller started to rotate inside the ring die.



When you feed basic materials right into the ring die pellet equipment through the receptacle, they are sent to the conditioner, where the raw materials are blended with vapor or butter. The conditioning of the raw materials aims to enhance the adhesive pressure and creating rate.



Then, the refined resources will certainly be sent to the pelletizing closet. Under the centrifugal pressure, they are distributed on the internal side of the ring die. The roller press the raw products into the holes on the ring die. The high temperature as well as high pressure reason physical as well as chemical adjustments to the raw products.



When they are ejected from the ring die, they end up being strong cylindrical sticks. The sticks grow longer, until they are reduced by the slicer outside the ring die. Then the pellets fall down as well as come out through the outlet.



2 sorts of ring die pellet equipment

According to various placements of the ring die, there are vertical ring die pellet equipment as well as horizontal ring die pellet equipment.



In the straight kind, 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 vertical kind, the ring die is placed flat. The feed receptacle is right over the ring die, as well as the raw products comes under the ring die straight.



In the vertical ring die pellet machine, both the roller and ring die turn. They create centrifugal force and distribute basic materials consistently. In the horizontal ring die pellet equipment, only the ring die rotates. The raw materials are dispersed in the ring die by the screw feeder.



Advantages and also weak point of ring die pellet equipment.

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



Due to the high production, the power consumption each is reduced. The abrasion between roller as well as die is smaller. The procedure and also upkeep is easy. The pellets are consistent in size.
