Pellet mill die and roller style and maker<br>
Roller and die is the core part of the pellet machine They establishes the developing rate as well as pellet high quality. They are also the most wearable components. This write-up introduces the design of roller as well as die in 2 types of pellet machine TICO is an expert flat die pellet machine supplier in China. We supply roller, flat die and other extra components for the pellet machine.



Flat die in pellet machine.

In flat die pellet machine, the die is a disc with several openings on it. It is constructed from ductile cast iron. After carburizing as well as quenching treatment, the hardness is 55-60HRC. The size of the holes are from 2.5 mm to 10mm. The most popular dimensions are 6mm, 8mm and also 10mm. To adjust to various materials as well as production requirement, the density and hole dimensions are various.



The working life of a flat die is 300-500 hrs. When one side has worn, it can be utilized with the opposite side. The size as well as dimension of the hole is created based on a great deal of experiments, to ensure that it accomplishes the most effective compression ratio for 30 biomass materials.



The flat die demand to be changed when it wears out. It does not take much initiatives. Just loosen the lock nuts on both sides, remove the upper chassis and also get the roller and also flat die. TICO provides remarkable extra components for the pellet machine, including roller as well as die.




Roller in flat die pellet machine.

In flat die pellet machine, the rollers are installed on the major shaft. 2 or even more rollers are attached by a roller shaft. go now are cyndrical tubes with many skid-proof ace on its surface area. During working, the roller shaft rotates around the major shaft, and the rollers turn around the main shaft at the same time. The diameters of the rollers vary with the production capability.



The solidity of rollers is less than that of flat die, so that they lower the endure flat die, as well as extend their working life. All rollers need to have the exact same clearance with the flat die to attain uniform pressure. The clearance is in between 0.1-0.3 mm.




The roller embraces conical shape to make certain the turning rate at the 2 ends are the same. This layout can avoid sliding of the roller, reduce energy waste, as well as minimize the wear of flat die. Besides, it takes on an screw central stress change tool. It allows you to adjust the clearance between roller as well as die, so regarding adapt to different materials as well as ensure molding impact.



Exactly how do the roller and flat die job?

When the raw products are fed right into the pellet machine with the hopper. They fall on the flat die as well as roller. The roller turns driven by the primary shaft, as well as distribute the raw products on the flat die equally. During turning, the roller and flat die kinds solid pressure as well as portion, which will certainly warm up the compression chamber to 80 ℃. In this condition, the products become soften as well as very easy to mold.



The downward pressure from the roller capture the raw materials into the holes on flat die, in which they are developed into cylindrical strips. The strips come to be much longer and longer as the roller keep 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 drop as well as release from the electrical outlet. These strips are what we call "wood pellets".



Flat die and also sound die pellet mill contrast

Flat die pellet machine is suitable for home use and also little workshop manufacturing. It costs reduced. The dimension is small as well as the production is fairly low. For big scale production, ring die pellet machine has more benefits. It has large production capability and also reduced power intake, however the size and cost is a lot larger. The major distinction between ring die and flat die pellet machine are the shape of the dies and 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) and stainless-steel, and processed by create and also stamp, reducing, drilling and warm therapy. The strength of the ring die is influenced by the variety of holes. The bigger the size of openings, the much less the number.



Rollers in ring die pellet machine

The rollers of ring die pellet machine are normally made of high-carbon steel or cooled actors iron. It should has higher firmness than the ring die, to ensure that it can realize the most effective compression effect and also uniform 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 products.



Just how do the roller as well as ring die job?

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



The raw materials were first fed into the conditioner for blending. After that they are shared to the compression chamber by a screw feeder. In the compression chamber, the rollers are still and the ring die rotates drive by the electrical motor. As https://satellitesandsirens.com/ as the raw materials are grabbed by the ring die, they are squeezed into the holes. The heat and stress create physical and chemical changes to the raw products. When they are extruded out from the ring die, there are slicers that cut them off. As well as the pellets falls down and venture out through the outlet.
