Pellet mill die and also roller design and maker<br>
Roller and die is the core part of the pellet machine They figures out the forming rate as well as pellet top quality. They are also the most wearable components. This write-up presents the design of roller as well as die in 2 sorts of pellet machine TICO is an expert flat die pellet machine maker in China. We provide roller, flat die and other spare parts for the pellet machine.



Flat die in pellet machine.

In flat die pellet machine, the die is a disc with several holes on it. It is made from ductile cast iron. After carburizing and relieving therapy, the hardness is 55-60HRC. The dimension of the holes are from 2.5 mm to 10mm. The most popular sizes are 6mm, 8mm and also 10mm. To adjust to various products and also production requirement, the thickness and also opening dimensions are different.



The working life of a flat die is 300-500 hrs. When one side has actually broken, it can be used with the other side. The size and also dimension of the hole is designed based on a great deal of experiments, so that it accomplishes the very best compression ratio for 30 biomass materials.



The flat die need to be changed when it wears. It does not take much efforts. Just loosen the lock nuts on both sides, remove the upper framework and also obtain the roller and also flat die. TICO supplies remarkable spare components for the pellet machine, including roller and die.



Roller in flat die pellet machine.

In flat die pellet machine, the rollers are installed on the primary shaft. 2 or more rollers are attached by a roller shaft. The rollers are cylinders with several skid-proof ace on its surface area. Throughout working, the roller shaft rotates around the primary shaft, and also the rollers turn around the primary shaft at the same time. The diameters of the rollers differ with the manufacturing capacity.



The firmness of rollers is lower than that of flat die, to make sure that they minimize the wear on flat die, as well as extend their functioning life. All rollers ought to have the same clearance with the flat die to achieve uniform stress. The clearance is in between 0.1-0.3 mm.




The roller embraces conical form to make certain the rotating speed at the 2 ends coincide. This style can avoid sliding of the roller, decrease energy waste, and decrease the wear of flat die. Besides, it adopts an screw main stress modification device. It permits you to change the clearance in between roller as well as die, so as to adjust to different materials as well as ensure molding result.



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

When the raw products are fed into the pellet machine via the hopper. They fall on the flat die and also roller. hemp pellet mill rotates driven by the main shaft, as well as distribute the raw products on the flat die evenly. During turning, the roller as well as flat die forms strong stress and portion, which will heat up the compression chamber to 80 ℃. In this problem, the materials become soften as well as simple to mold and mildew.



The downward pressure from the roller press the raw products right into the holes on flat die, in which they are developed into cylindrical strips. The strips become longer and also 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 cutting them off. pto pelletizer cut strips drop and release from the electrical outlet. These strips are what we call "wood pellets".



Flat die and also ring die pellet mill comparison

Flat die pellet machine appropriates for house usage and small workshop manufacturing. It sets you back reduced. The size is little as well as the manufacturing is reasonably reduced. For big range manufacturing, ring die pellet machine has even more benefits. It has big manufacturing capability and also low power consumption, however the dimension as well as price is much larger. The significant difference in between ring die and also flat die pellet machine are the form of the dies as well as the placement of rollers.



Ring die in pellet machine

Ring die is an annulus with lots of openings on it. It is constructed from carbon steel (alloy steel) and stainless-steel, and refined by build as well as mark, cutting, drilling and also heat therapy. pellet press machine for sale of the ring die is influenced by the number 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 usually made of high-carbon steel or cooled actors iron. It must has higher hardness than the ring die, to ensure that it can realize the very best compression result as well as consistent abrasion. The suitable clearance between the rollers and also ring die is 0.1-0.4 mm. There are axial grooves on the surface of the roller to get the raw materials.



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

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



The raw materials were first fed into the conditioner for blending. Then 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 materials are gotten by the ring die, they are squeezed into the holes. The heat as well as pressure create physical and chemical changes to the raw materials. When they are extruded out from the ring die, there are slicers that cut them off. As well as the pellets drops and also venture out via the outlet.
