Pellet mill die and roller layout and also producer<br>
Roller and also die is the core part of the pellet machine They determines the creating price and pellet high quality. They are also the most wearable parts. This write-up introduces the layout of roller as well as die in 2 types of pellet machine TICO is a specialist flat die pellet machine supplier in China. We supply roller, flat die and also various other spare parts for the pellet machine.



Flat die in pellet machine.

In flat die pellet machine, the die is a disc with lots of openings on it. It is constructed from ductile actors iron. After carburizing as well as satiating therapy, the hardness is 55-60HRC. The size of the holes are from 2.5 mm to 10mm. One of the most preferred sizes are 6mm, 8mm and also 10mm. To adjust to various products as well as production demand, the thickness and also opening dimensions are different.



The working life of a flat die is 300-500 hours. When wood pellet making machine price has actually worn, it can be utilized with the other side. The size and dimension of the hole is designed based upon a multitude of experiments, to ensure that it achieves the very best compression ratio for 30 biomass materials.



The flat die requirement to be replaced when it wears out. It does not take much efforts. Simply loosen up the lock nuts on both sides, remove the top chassis and obtain the roller and also flat die. TICO gives premium extra parts 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 attached by a roller shaft. The rollers are cyndrical tubes with several skid-proof ace on its surface area. During functioning, the roller shaft turns around the main shaft, and also the rollers revolve around the major shaft at the same time. The diameters of the rollers differ with the manufacturing ability.




The solidity of rollers is lower than that of flat die, to make sure that they reduce the wear on flat die, as well as extend their functioning life. All rollers ought to have the same clearance with the flat die to accomplish uniform pressure. The clearance is between 0.1-0.3 mm.



The roller embraces conical form to make sure the revolving rate at the 2 ends coincide. This layout can stay clear of sliding of the roller, minimize power waste, and minimize the wear of flat die. Besides, it embraces an screw main pressure change device. It enables you to change the clearance between roller and also die, so regarding adapt to various products and make sure molding effect.



Exactly how do the roller and also flat die work?

When the raw products are fed right into the pellet machine via the hopper. They fall on the flat die and also roller. The roller turns driven by the main shaft, as well as disperse the raw products on the flat die uniformly. During turning, the roller and also flat die forms solid pressure as well as portion, which will certainly warm up the compression chamber to 80 ℃. In this condition, the materials come to be soften and very easy to mold and mildew.



The down stress from the roller squeeze the raw materials right into the holes on flat die, in which they are created into round strips. The strips end up being longer and also longer as the roller keep squeezing the raw products. When the strips come out from all-time low of the holes, there is a slicer reducing them off. The cut strips drop and also discharge from the outlet. These strips are what we call "wood pellets".



Apartment die as well as sound die pellet mill contrast

Apartment die pellet machine is suitable for home usage and also little workshop manufacturing. It costs low. The dimension is tiny and the production is reasonably low. For large range manufacturing, ring die pellet machine has more advantages. It has large manufacturing ability and also reduced power intake, yet the size and price is much larger. The significant distinction between ring die and also flat die pellet machine are the shape of the dies and also the position of rollers.



Ring die in pellet machine

Ring die is an annulus with many holes on it. It is made from carbon steel (alloy steel) as well as stainless steel, and also refined by forge and stamp, cutting, drilling as well as warmth treatment. wood pellet maker for sale of the ring die is influenced by the number of holes. The bigger the dimension of holes, the less the number.



Rollers in ring die pellet machine

The rollers of ring die pellet machine are generally made from high-carbon steel or cooled actors iron. It needs to has higher hardness than the ring die, so that it can understand the best compression result as well as consistent abrasion. The ideal clearance in between the rollers and ring die is 0.1-0.4 mm. There are axial grooves on the surface of the roller to get the raw materials.



Just how do the roller and also ring die job?

In ring die pellet machine, the 2 rollers are installed inside the ring die. The roller put pressure external on the inner wall surface of the ring die.



The raw materials were first fed right into the conditioner for mixing. After that they are conveyed to the compression chamber by a screw feeder. In the compression chamber, the rollers are still and also the ring die rotates drive by the electric motor. As long as the raw products are grabbed by the ring die, they are squeezed into the holes. The heat as well as pressure trigger physical and also chemical changes to the raw materials. When they are extruded out from the ring die, there are slicers that reduced them off. As well as the pellets drops and also venture out via the electrical outlet.
