Pellet mill die and also roller style and also manufacturer<br>
Roller and also die is the core part of the pellet machine They identifies the developing rate and also pellet quality. They are also one of the most wearable components. This post presents 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 also other spare parts for the pellet machine.



Apartment die in pellet machine.

In flat die pellet machine, the die is a disc with lots of openings on it. It is made from ductile cast iron. After carburizing as well as relieving treatment, the hardness is 55-60HRC. poultry pellet making machine of the holes are from 2.5 mm to 10mm. The most preferred sizes are 6mm, 8mm as well as 10mm. To adapt to various products as well as manufacturing need, the thickness and hole sizes are different.



The working life of a flat die is 300-500 hrs. When one side has actually broken, it can be utilized with the opposite side. The size and size of the hole is developed based on a lot of experiments, to make sure that it attains the most effective compression ratio for 30 biomass materials.



The flat die requirement to be changed when it wears out. It doesn't take much efforts. Just loosen the lock nuts on both sides, remove the upper framework and also obtain the roller and flat die. TICO provides remarkable spare parts for the pellet machine, consisting of roller and also die.



Roller in flat die pellet machine.

In flat die pellet machine, the rollers are installed 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 rotates around the main shaft, and also the rollers turn around the main shaft at the same time. The diameters of the rollers vary with the manufacturing capacity.



The solidity of rollers is less than that of flat die, to make sure that they reduce the endure flat die, and also extend their functioning life. All rollers should have the same clearance with the flat die to accomplish uniform stress. The clearance is between 0.1-0.3 mm.



The roller adopts tapered shape to ensure the rotating rate at the 2 ends are the same. This design can avoid slipping of the roller, lower power waste, and lower the wear of flat die. Besides, floating fish feed pellet making machine adopts an screw central stress adjustment device. It permits you to readjust the clearance between roller and also die, so as to adapt to various materials and also ensure molding effect.



Exactly how do the roller and flat die work?

When the raw materials are fed right into the pellet machine with the receptacle. They fall on the flat die and roller. The roller revolves driven by the major shaft, and also distribute the raw products on the flat die evenly. During turning, the roller as well as flat die kinds strong pressure and portion, which will heat up the compression chamber to 80 ℃. In this condition, the materials come to be soften and also very easy to mold and mildew.



The descending pressure from the roller squeeze the raw products into the holes on flat die, in which they are formed right into round strips. The strips come to be much longer and much longer as the roller maintain squeezing the raw materials. When the strips appear from the bottom of the holes, there is a slicer cutting them off. The cut strips fall down as well as discharge from the electrical outlet. These strips are what we call "wood pellets".




Apartment die and ring die pellet mill comparison

Apartment die pellet machine appropriates for home usage as well as small workshop production. It costs low. The dimension is small and also the production is relatively reduced. For big scale manufacturing, ring die pellet machine has more advantages. It has huge manufacturing capability and low power consumption, but the dimension and also expense is much bigger. The significant distinction between ring die as well as flat die pellet machine are the shape of the dies as well as 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, as well as processed by forge and also mark, cutting, exploration and warm treatment. The toughness 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 of high-carbon steel or cooled actors iron. It needs to has greater firmness than the ring die, to make sure that it can understand the very best compression effect and also uniform abrasion. The suitable clearance between the rollers and also ring die is 0.1-0.4 mm. There are axial grooves on the surface area 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 mounted inside the ring die. The roller placed pressure outward on the inner wall surface of the ring die.



The raw materials were first fed into the conditioner for mixing. After that they are communicated 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 products are gotten hold of by the ring die, they are squeezed into the holes. The high temperature as well as pressure cause physical as well as chemical modifications to the raw materials. When they are extruded out from the ring die, there are slicers that cut them off. And also the pellets falls down and also get out through the outlet.
