Pellet mill die as well as roller design as well as supplier<br>
Roller as well as die is the core part of the pellet machine They figures out the creating price and also pellet quality. They are also one of the most wearable components. This write-up presents the style of roller and also die in 2 sorts of pellet machine TICO is an expert flat die pellet machine producer in China. We provide roller, flat die and also various other spare components 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 pliable cast iron. After carburizing and relieving therapy, the firmness is 55-60HRC. The size of the holes are from 2.5 mm to 10mm. The most popular sizes are 6mm, 8mm as well as 10mm. To adapt to various materials and also manufacturing demand, the density and hole dimensions are different.




The functioning life of a flat die is 300-500 hrs. When one side has actually worn, it can be made use of with the other side. The size as well as size of the hole is designed based upon a large number of experiments, so that it achieves the very best compression proportion for 30 biomass materials.



The flat die need to be replaced when it breaks. It does not take much efforts. Just loosen the lock nuts on both sides, eliminate the upper chassis and also secure the roller and also flat die. hammer mill pellet maker gives remarkable spare components 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 even more rollers are attached by a roller shaft. The rollers are cylinders with lots of skid-proof ace on its surface. Throughout working, the roller shaft turns around the major shaft, as well as the rollers turn around the primary shaft at the same time. The diameters of the rollers differ with the production capacity.



The firmness of rollers is less than that of flat die, so 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 accomplish uniform pressure. The clearance is between 0.1-0.3 mm.



The roller embraces conical shape to make sure the revolving rate at the 2 ends are the same. This layout can avoid sliding of the roller, lower energy waste, as well as reduce the wear of flat die. Besides, it embraces an screw main stress modification tool. It enables you to readjust the clearance between roller as well as die, so as to adapt to various products as well as make sure molding effect.




Just 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 as well as roller. The roller revolves driven by the major shaft, and distribute the raw materials on the flat die evenly. Throughout revolving, the roller and also flat die kinds strong stress as well as fraction, which will certainly warm up the compression chamber to 80 ℃. In this problem, the materials end up being soften as well as simple to mold.



The downward stress from the roller press the raw materials into the holes on flat die, in which they are created into round strips. The strips come to be longer and much longer as the roller maintain squeezing the raw materials. When the strips appear from all-time low of the holes, there is a slicer reducing them off. The cut strips drop and release from the outlet. These strips are what we call "wood pellets".



Flat die and call die pellet mill contrast

Apartment die pellet machine appropriates for house usage as well as small workshop production. It costs low. The dimension is little and also the production is reasonably reduced. For large range production, ring die pellet machine has more benefits. It has large production capability and also low power intake, but the dimension and expense is a lot bigger. The significant difference between ring die and flat die pellet machine are the form of the dies as well as the setting of rollers.



Ring die in pellet machine

Ring die is an annulus with lots of openings on it. It is made from carbon steel (alloy steel) and also stainless-steel, and processed by create and stamp, reducing, drilling and warm treatment. The strength of the ring die is affected by the variety of holes. The bigger the dimension of holes, the less the number.



Rollers in ring die pellet machine

The rollers of ring die pellet machine are typically constructed from high-carbon steel or cooled actors iron. rice husk pellet machine should has greater firmness than the ring die, to make sure that it can understand the most effective compression result and consistent 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 area of the roller to grab the raw products.



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 put pressure outside on the inner wall of the ring die.



The raw products were first fed into the conditioner for mixing. Then they are conveyed 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 grabbed by the ring die, they are squeezed right into the holes. The heat as well as pressure trigger physical and chemical modifications to the raw materials. When they are extruded out from the ring die, there are slicers that reduced them off. And also the pellets drops and go out through the outlet.
