Pellet mill die and roller design and supplier<br>
Roller as well as die is the core part of the pellet machine They identifies the creating rate and also pellet quality. They are additionally the most wearable parts. This short article introduces the style of roller as well as die in 2 kinds of pellet machine TICO is an expert flat die pellet machine producer in China. sawdust pellet machine for sale supply roller, flat die as well as other extra parts for the pellet machine.



Apartment die in pellet machine.

In flat die pellet machine, the die is a disc with lots of holes on it. It is made from pliable actors iron. After carburizing and appeasing treatment, the firmness is 55-60HRC. The dimension of the holes are from 2.5 mm to 10mm. One of the most popular sizes are 6mm, 8mm and also 10mm. To adapt to various products and production demand, the density and opening dimensions are different.



The functioning life of a flat die is 300-500 hrs. When one side has actually broken, it can be made use of with the other side. The length and dimension of the hole is designed based on a great deal of experiments, to make sure that it achieves the very best compression ratio for 30 biomass products.



The flat die need to be changed when it wears out. It does not take much efforts. Just loosen the lock nuts on both sides, get rid of the upper framework and secure the roller as well as flat die. TICO offers premium spare components for the pellet machine, including roller and die.



Roller in flat die pellet machine.

In flat die pellet machine, the rollers are set up on the main shaft. 2 or more rollers are connected by a roller shaft. The rollers are cylinders with several skid-proof ace on its surface. Throughout functioning, the roller shaft turns around the main shaft, as well as the rollers rotate around the major shaft at the same time. The sizes of the rollers vary with the production capability.



The firmness of rollers is lower than that of flat die, to ensure that they decrease the wear on flat die, as well as extend their functioning life. All rollers must have the exact same clearance with the flat die to achieve consistent pressure. small wood pellet making machine is in between 0.1-0.3 mm.



The roller takes on conical form to make certain the rotating speed at the 2 ends coincide. This layout can prevent slipping of the roller, reduce energy waste, as well as reduce the wear of flat die. Besides, it takes on an screw central stress change device. It permits you to adjust the clearance between roller and also die, so regarding adjust to different materials and make certain molding impact.



Exactly how do the roller and flat die work?

When the raw materials are fed into the pellet machine via the hopper. They fall on the flat die as well as roller. The roller rotates driven by the primary shaft, and also disperse the raw products on the flat die uniformly. During revolving, the roller and flat die forms solid stress and portion, which will heat up the compression chamber to 80 ℃. In this problem, the products come to be soften and also very easy to mold.




The downward stress from the roller squeeze the raw materials into the holes on flat die, in which they are created into cylindrical strips. The strips end up being longer and also longer as the roller maintain pressing the raw products. When the strips appear from all-time low of the holes, there is a slicer cutting them off. The cut strips fall down and also discharge from the outlet. These strips are what we call "wood pellets".




Apartment die and also ring die pellet mill comparison

Flat die pellet machine is suitable for house usage and small workshop manufacturing. It sets you back reduced. The size is small and the manufacturing is fairly reduced. For large range production, ring die pellet machine has even more advantages. It has huge production capability as well as low power usage, but the dimension and cost is a lot larger. The major difference between ring die as well as flat die pellet machine are the shape of the dies as well as the placement of rollers.



Ring die in pellet machine

Ring die is an annulus with several openings on it. It is made from carbon steel (alloy steel) and stainless steel, and also refined by forge and stamp, reducing, exploration and heat therapy. The stamina of the ring die is influenced by the number of holes. The larger the dimension of holes, the less the number.



Rollers in ring die pellet machine

The rollers of ring die pellet machine are typically made of high-carbon steel or cooled cast iron. It should has greater hardness than the ring die, to make sure that it can recognize the very best compression effect as well as uniform abrasion. The appropriate clearance between the rollers and ring die is 0.1-0.4 mm. There are axial grooves on the surface area of the roller to get hold of the raw materials.



Just how do the roller and ring die job?

In ring die pellet machine, the 2 rollers are mounted inside the ring die. The roller put pressure outside on the internal wall surface of the ring die.



The raw products were first fed right into the conditioner for blending. Then they are shared to the compression chamber by a screw feeder. In the compression chamber, the rollers are still as well as the ring die rotates drive by the electrical motor. As long as the raw materials are gotten by the ring die, they are squeezed right into the holes. The heat as well as stress cause physical and also chemical modifications to the raw materials. When they are extruded out from the ring die, there are slicers that reduced them off. And the pellets falls down as well as venture out with the electrical outlet.
