Pellet mill die as well as roller style and also supplier<br>
Roller and die is the core part of the pellet machine They determines the developing price as well as pellet quality. They are likewise one of the most wearable components. This article presents the design of roller and also die in 2 sorts of pellet machine TICO is an expert flat die pellet machine maker 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 numerous holes on it. It is made from pliable actors iron. After carburizing as well as appeasing therapy, the firmness is 55-60HRC. The size of the holes are from 2.5 mm to 10mm. The most prominent sizes are 6mm, 8mm and also 10mm. To adapt to various materials and manufacturing demand, the thickness and also opening sizes are different.



The working life of a flat die is 300-500 hours. When one side has actually worn, it can be used with the opposite. The length and also dimension of the hole is made based upon a great deal of experiments, to ensure that it achieves the best compression ratio for 30 biomass materials.



The flat die need to be changed when it wears. It does not take much efforts. Simply loosen the lock nuts on both sides, eliminate the upper chassis as well as take out the roller and flat die. TICO offers remarkable spare components for the pellet machine, including roller and also 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 connected by a roller shaft. The rollers are cyndrical tubes with several skid-proof ace on its surface. Throughout working, the roller shaft turns around the major shaft, as well as the rollers rotate around the primary shaft at the same time. The sizes of the rollers differ with the manufacturing capacity.



The firmness of rollers is less than that of flat die, to make sure that they lower 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 attain uniform stress. The clearance is between 0.1-0.3 mm.



The roller embraces tapered shape to ensure the revolving rate at the 2 ends coincide. hemp pellet mill can avoid slipping of the roller, reduce power waste, and also decrease the wear of flat die. Besides, it takes on an screw central pressure adjustment tool. It enables you to change the clearance between roller and die, so as to adjust to various materials as well as guarantee molding effect.



Just how do the roller and flat die job?

When the raw products are fed into the pellet machine with the receptacle. They fall on the flat die and roller. The roller rotates driven by the main shaft, and also distribute the raw products on the flat die evenly. Throughout revolving, the roller and also flat die types solid stress and also portion, which will certainly warm up the compression chamber to 80 ℃. In this problem, the products come to be soften and very easy to mold.



The downward stress from the roller capture the raw products into the holes on flat die, in which they are formed into round strips. The strips become much longer and also longer as the roller keep squeezing the raw materials. When the strips appear from all-time low of the holes, there is a slicer cutting them off. The cut strips fall down as well as release from the outlet. These strips are what we call "wood pellets".



Flat die and also ring die pellet mill contrast

Apartment die pellet machine appropriates for residence use and also little workshop production. It costs reduced. The size is tiny and the manufacturing is reasonably reduced. For alfalfa pellet mill for sale , ring die pellet machine has even more advantages. It has large production ability as well as low power usage, yet the size as well as price is a lot larger. The significant distinction in between ring die and also flat die pellet machine are the form of the dies and also the setting 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 also processed by forge and also mark, cutting, drilling as well as warmth treatment. The strength of the ring die is affected by the number of openings. The bigger the dimension of openings, 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 chilled actors iron. It must has higher solidity than the ring die, to ensure that it can understand the very best compression effect 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 order the raw products.



How do the roller and ring die work?

In ring die pellet machine, the 2 rollers are set up inside the ring die. The roller placed stress outside 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 ordered by the ring die, they are pressed into the holes. The heat as well as stress cause physical as well as chemical changes to the raw materials. When they are extruded out from the ring die, there are slicers that reduced them off. And also the pellets falls down and get out through the outlet.
