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



Ring die pellet mill has large quantity and high capacity. It appropriates for factory use and also large-scale production. Flat die pellet mill is little and mobile. It has reduced ability, appropriate for house use and small-scale production. The cost of flat die pellet mill is a lot lower 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, a top closet, a discharge outlet, a pin box, transmission, a transmission shaft, an electric control cabinet, an electric motor, a engine base, and 4 wheels, and so on.



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



The core components: roller and flat die

The pelletizing part of the flat die pellet equipment is a press roller and also a flat die. https://richipelletmachine.blog.jp/archives/18498782.html are mounted in the upper closet. There are 2-4 rollers installed on the 2 ends of the roller shaft. The rollers have grooves on the surface. The roller and also flat die is constructed from exceptional alloy steel, whose hardness is 55-60 HRC.



There are numerous openings on the flat die, whose diameter is from 2.5 mm to 10mm, and also 6mm, 8mm and also 10mm are one of the most usual types. They realize the most effective compression proportion with a large number of experiments, appropriate for greater than 30 type of materials.



The clearance in between the roller and 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 adjust the clearance to adjust to various materials.



Just how does a flat die pellet equipment job?

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



When you start the pellet machine, the electric motor runs and also bring along the primary shaft through the transmission. The press roller is mounted on the primary shaft, so it turns around the primary shaft. At the same time, the rollers revolve around the roller shaft.



The turning press forms solid pressure and press the raw products into the holes on the flat die. The raw products obtain molded in these openings. When they are ejected, they end up being solid cyndrical tubes. At the same time, the solid rubbing between roller and die warm up the raw products to over 80 ° C, where the lignin and fibers obtain soft. They boost the adhesive pressure of products.



The diameter of the pellets is determined by the hole size of the flat die, while the length is determined 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 cut them into particular length. 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 kinds of flat die pellet equipment

Apartment 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 major shaft. When the machine works, the flat die rotates and the roller maintain still. The later one has the press roller set up on the primary shaft. The roller rotates with the primary shaft, while the flat die keep still.



Roller-turned kind takes on a lot more reliable structure. It has bigger ability and more durable transmission. However Die-turned type is extra small as well as mobile, with lower expense. Of course, both of them have the ability to make high-grade pellets.



Advantages and also weakness of flat die pellet equipment

Apartment die pellet mill has straightforward structure. Richi machine is little, light and also portable. The price is much lower than ring die pellet equipment It is very easy to run as well as preserve. You can observe the pelletizing procedure and also resolve any mistake in time. So it is preferred with farmers, home individuals, and also tiny fuel production plant.



The flat dies are putting on parts, you need to change it on a regular basis. But it can be made use of with both sides. You can turn it over when one side has broken. In this way you can expand their working life as well as minimize expense.



On the other hand, the moving range are different in the inner and also outer side of roller, which trigger the slide of rollers and abrasion on the flat die. Currently, numerous flat die pellet equipment embrace conical roller to solve this issue. TICO flat die pellet machine adopts tapered roller and exceptional alloy steel in the flat die.

Besides, the get in touch with area of roller and also flat die is smaller sized than ring die pellet machine, so the production capacity as well as creating price is lower.



Just how does a ring die pellet equipment work?

Structure of ring die pellet equipment

A ring die pellet machine is made up of a screw feeder, conditioner, roller as well as ring die, release port, electrical motor, gearbox, pedestal.



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



When you feed raw materials into the ring die pellet machine 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 boost the adhesive force and also creating price.



After that, the refined basic materials will certainly be transferred to the pelletizing cupboard. Under the centrifugal pressure, they are distributed on the inner side of the ring die. The roller press the raw materials into the holes on the ring die. The high temperature and also high pressure reason physical as well as chemical changes to the raw products.



When they are squeezed out from the ring die, they come to be strong round sticks. The sticks expand much longer, till they are cut by the slicer outside the ring die. After that the pellets drop as well as appear through the outlet.



Two kinds of ring die pellet machine

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



In the horizontal kind, the ring die is put vertically. When basic materials fall down from the conditioner, they are fed into the ring die horizontally by a forced feeder. In the upright kind, the ring die is placed horizontally. The feed receptacle is right over the ring die, and the raw materials falls under the ring die directly.



In the vertical ring die pellet equipment, both the roller and ring die turn. They form centrifugal force and also distribute resources evenly. In the horizontal ring die pellet equipment, only the ring die rotates. The raw products are distributed in the ring die by the screw feeder.



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

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



Due to the high manufacturing, the power consumption each is low. The abrasion in between roller and also die is smaller. The operation as well as upkeep is easy. The pellets are uniform in size.
