Pellet mill die and roller style as well as manufacturer<br>
Roller and die is the core part of the pellet machine They identifies the developing price and also pellet high quality. They are additionally the most wearable parts. This short article introduces the design of roller as well as die in 2 sorts of pellet machine TICO is an expert flat die pellet machine supplier in China. We provide roller, flat die and various other spare components for the pellet machine.



Flat die in pellet machine.

In flat die pellet machine, the die is a disc with many openings on it. It is made of ductile cast iron. After carburizing and relieving treatment, the firmness is 55-60HRC. The dimension of the holes are from 2.5 mm to 10mm. The most prominent sizes are 6mm, 8mm and 10mm. To adapt to various materials and also production requirement, the density and hole sizes are different.




The working life of a flat die is 300-500 hrs. When richi pellet machine has actually broken, it can be utilized with the opposite. The length and also dimension of the hole is created based upon a multitude of experiments, to ensure that it achieves the very best compression proportion for 30 biomass materials.



The flat die need to be changed when it wears. It doesn't take much initiatives. Simply loosen up the lock nuts on both sides, get rid of the upper framework and get the roller as well as flat die. TICO offers remarkable spare parts for the pellet machine, including roller and 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. During working, the roller shaft turns around the main shaft, and the rollers turn around the primary shaft at the same time. The diameters of the rollers differ with the production capability.



The hardness of rollers is less than that of flat die, so that they decrease the endure flat die, and extend their functioning life. All rollers ought to have the very same clearance with the flat die to achieve uniform pressure. The clearance is between 0.1-0.3 mm.



The roller takes on conical shape to make sure the turning speed at the 2 ends are the same. This style can avoid sliding of the roller, minimize power waste, and lower the wear of flat die. Besides, it embraces an screw central pressure change device. It enables you to change the clearance in between roller and also die, so as to adjust to different products as well as guarantee molding result.



How do the roller as well as flat die work?

When the raw products are fed right into the pellet machine via the receptacle. They fall on the flat die as well as roller. The roller turns driven by the main shaft, as well as distribute the raw materials on the flat die equally. During rotating, the roller and flat die forms solid stress and also portion, which will heat up the compression chamber to 80 ℃. In this problem, the products become soften and also very easy to mold.



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



Flat die as well as ring die pellet mill comparison

Apartment die pellet machine appropriates for home use and little workshop manufacturing. It sets you back reduced. The size is small and also the production is relatively low. For large range manufacturing, ring die pellet machine has even more advantages. It has big production capability as well as reduced power usage, yet the dimension as well as price is much bigger. The significant difference in between ring die as well as flat die pellet machine are the form of the dies as well as the position of rollers.



Ring die in pellet machine


Ring die is an annulus with many openings on it. It is constructed from carbon steel (alloy steel) and stainless-steel, and also refined by create as well as stamp, reducing, drilling and also warm therapy. The strength of the ring die is influenced by the variety of openings. The larger the dimension of holes, 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 should has greater hardness than the ring die, to ensure that it can understand the best compression result and uniform abrasion. hemp pellet machine in between the rollers and ring die is 0.1-0.4 mm. There are axial grooves on the surface of the roller to grab the raw materials.



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

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



The raw products were first fed right into the conditioner for blending. Then they are conveyed to the compression chamber by a screw feeder. In he said , the rollers are still and the ring die rotates drive by the electrical motor. As long as the raw materials are grabbed by the ring die, they are pressed right into the holes. The heat as well as stress cause physical and 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 drops as well as venture out with the outlet.
