Pellet mill die and also roller style as well as producer<br>
Roller as well as die is the core part of the pellet machine They determines the developing rate and also pellet quality. They are likewise the most wearable parts. This article presents the layout of roller and die in 2 sorts of pellet machine TICO is a professional flat die pellet machine manufacturer in China. We provide roller, flat die and other extra parts for the pellet machine.



Flat die in pellet machine.

In flat die pellet machine, the die is a disc with lots of holes on it. It is constructed from pliable cast iron. After carburizing as well as appeasing treatment, the hardness is 55-60HRC. The size of the holes are from 2.5 mm to 10mm. One of the most prominent sizes are 6mm, 8mm and 10mm. To adjust to various materials and production requirement, the thickness as well as hole sizes are different.



The functioning life of a flat die is 300-500 hrs. When one side has actually worn, it can be used with the other side. The size and dimension of the hole is developed based on a multitude of experiments, to ensure that it accomplishes the most effective compression ratio for 30 biomass products.



The flat die demand to be changed when it wears. It does not take much initiatives. Simply loosen the lock nuts on both sides, remove the upper framework and also obtain the roller as well as flat die. TICO supplies premium spare parts for the pellet machine, including roller as well as die.



Roller in flat die pellet machine.

In flat die pellet machine, the rollers are mounted on the major shaft. 2 or more rollers are attached by a roller shaft. The rollers are cylinders with several skid-proof ace on its surface. Throughout working, the roller shaft revolves 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 ability.



The solidity of rollers is less than that of flat die, to make sure that they minimize the endure flat die, as well as prolong their working life. All rollers ought to have the exact same clearance with the flat die to attain uniform pressure. The clearance is between 0.1-0.3 mm.



The roller adopts tapered shape to guarantee the revolving rate at the 2 ends coincide. This style can avoid slipping of the roller, reduce power waste, and reduce the wear of flat die. Besides, it embraces an screw central pressure change device. It enables you to adjust the clearance between roller and die, so regarding adjust to various products and make certain molding effect.



How do the roller and also flat die work?

When the raw materials are fed into the pellet machine with the hopper. They fall on the flat die as well as roller. The roller rotates driven by the primary shaft, and disperse the raw materials on the flat die uniformly. During revolving, the roller and flat die types solid pressure as well as fraction, which will certainly heat up the compression chamber to 80 ℃. In this problem, the products become soften and also simple to mold and mildew.



The downward stress from the roller squeeze the raw products right into the holes on flat die, in which they are created right into cylindrical strips. The strips become much longer as well as longer as the roller keep squeezing the raw products. When the strips appear from all-time low of the holes, there is a slicer reducing them off. The cut strips drop as well as release from the outlet. These strips are what we call "wood pellets".



Flat die as well as call die pellet mill comparison

Apartment die pellet machine is suitable for residence usage as well as small workshop manufacturing. It costs low. The dimension is small and the production is reasonably low. For large range manufacturing, ring die pellet machine has even more benefits. It has big production ability and also low power intake, however the dimension and price is much bigger. The major distinction in between ring die and also flat die pellet machine are the form of the dies and also the position of rollers.



Ring die in pellet machine


Ring die is an annulus with many openings on it. It is made from carbon steel (alloy steel) and also stainless-steel, and also processed by create and also mark, reducing, boring and warmth therapy. The strength of the ring die is affected by the variety of openings. feed pellet machine price of holes, the much 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. go right here should has higher solidity than the ring die, to ensure that it can realize the very best compression effect and uniform abrasion. The appropriate clearance between the rollers as well as ring die is 0.1-0.4 mm. There are axial grooves on the surface area of the roller to grab the raw materials.



Exactly how do the roller and also ring die job?

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




The raw products were first fed into the conditioner for blending. Then 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 electrical motor. As long as the raw materials are gotten by the ring die, they are squeezed right into the holes. The heat and pressure trigger physical and also chemical adjustments to the raw products. 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.
