Flat die in pellet machine.
In flat die pellet machine, the die is a disc with several holes on it. It is made of pliable cast 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. The most preferred sizes are 6mm, 8mm and also 10mm. To adapt to various products and also manufacturing need, the density and also opening sizes are different.
The functioning life of a flat die is 300-500 hours. When one side has broken, it can be used with the opposite. The length as well as dimension of the hole is developed based upon a large number of experiments, to make sure that it accomplishes the very best compression ratio for 30 biomass materials.
The flat die demand to be replaced when it wears out. It doesn't take much initiatives. Simply loosen up the lock nuts on both sides, get rid of the upper framework and also obtain the roller and flat die. TICO provides remarkable extra 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 attached by a roller shaft. The rollers are cylinders with many skid-proof ace on its surface area. During functioning, the roller shaft rotates around the primary shaft, and also the rollers rotate around the major shaft at the same time. The diameters of the rollers vary with the manufacturing capability.
The firmness of rollers is lower than that of flat die, to ensure that they reduce the endure flat die, and also extend their working life. All rollers need to have the same clearance with the flat die to attain uniform pressure. The clearance is between 0.1-0.3 mm.
The roller embraces conical form to make certain the revolving rate at the 2 ends are the same. This style can avoid sliding of the roller, decrease energy waste, and reduce the wear of flat die. Besides, it embraces an screw main stress adjustment gadget. It allows you to readjust the clearance in between roller and also die, so as to adapt to different products and also make sure molding effect.
Just how do the roller as well as flat die job?
When the raw materials are fed right into the pellet machine with the hopper. They fall on the flat die as well as roller. The roller revolves driven by the major shaft, and also disperse the raw products on the flat die equally. Throughout revolving, the roller and flat die kinds solid pressure and also portion, which will warm up the compression chamber to 80 ℃. In this condition, the products come to be soften and also simple to mold.
The down pressure from the roller squeeze the raw materials into the holes on flat die, in which they are developed into cylindrical strips. The strips end up being longer and also longer as the roller maintain pressing the raw materials. When the strips come out from all-time low of the holes, there is a slicer reducing them off. The cut strips drop and discharge from the outlet. These strips are what we call "wood pellets".
Flat die and also sound die pellet mill comparison
Apartment die pellet machine appropriates for residence use as well as small workshop production. It sets you back low. The size is small and also the production is fairly low. For big scale production, ring die pellet machine has more advantages. It has large production ability and also reduced power intake, but the dimension as well as price is much larger. sawdust pellet making machine in between ring die and 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 several openings on it. grain pellet mill is made from carbon steel (alloy steel) and stainless steel, as well as processed by forge and mark, reducing, exploration as well as heat therapy. The strength of the ring die is affected by the variety of holes. The bigger the size of openings, the less the number.
Rollers in ring die pellet machine
The rollers of ring die pellet machine are usually made from high-carbon steel or cooled actors iron. It must has higher hardness than the ring die, so that it can understand the best compression result and consistent abrasion. The ideal clearance between the rollers as well as ring die is 0.1-0.4 mm. There are axial grooves on the surface of the roller to grab the raw materials.
How do the roller and ring die work?
In ring die pellet machine, the 2 rollers are installed inside the ring die. The roller placed stress external on the inner wall of the ring die.
The raw products were first fed 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 ordered by the ring die, they are squeezed into the holes. The high temperature as well as pressure trigger physical as well as chemical adjustments to the raw products. When they are extruded out from the ring die, there are slicers that reduced them off. And also the pellets drops and also go out with the outlet.
