Pellet mill die and roller style and producer<br>
Roller and die is the core part of the pellet machine They figures out the developing rate as well as pellet quality. They are also one of the most wearable components. This post presents the style of roller and also die in 2 sorts of pellet machine TICO is a professional flat die pellet machine producer in China. wood pellet production machine 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 several holes on it. It is constructed from ductile actors iron. After carburizing and also satiating therapy, the firmness is 55-60HRC. The dimension of the holes are from 2.5 mm to 10mm. One of the most prominent dimensions are 6mm, 8mm and 10mm. To adapt to various materials as well as manufacturing requirement, the thickness and also hole dimensions are different.



The working life of a flat die is 300-500 hours. When one side has actually worn out, it can be used with the other side. The size as well as size of the hole is designed based on a great deal of experiments, so that it attains the best compression ratio for 30 biomass materials.



The flat die requirement to be replaced when it wears. It doesn't take much efforts. Simply loosen up the lock nuts on both sides, get rid of the top framework and get the roller as well as flat die. TICO gives premium spare parts for the pellet machine, including roller and die.



Roller in flat die pellet machine.

In flat die pellet machine, the rollers are set up on the primary shaft. 2 or even more rollers are attached by a roller shaft. The rollers are cylinders with numerous skid-proof ace on its surface. Throughout working, the roller shaft turns around the primary shaft, and also the rollers rotate around the major shaft at the same time. small wood pellet mills home use of the rollers vary with the manufacturing capability.



The solidity of rollers is less than that of flat die, so that they lower the wear on flat die, and also extend their working life. All rollers ought to have the very same clearance with the flat die to attain consistent stress. The clearance is between 0.1-0.3 mm.



The roller adopts tapered form to make sure the revolving speed at the 2 ends coincide. This layout can prevent sliding of the roller, minimize power waste, and also reduce the wear of flat die. Besides, it adopts an screw main stress adjustment gadget. It enables you to adjust the clearance in between roller and die, so as to adapt to various materials as well as make certain molding effect.



Just how do the roller and flat die job?

When the raw products are fed right into the pellet machine with the hopper. They fall on the flat die and also roller. The roller revolves driven by the major shaft, as well as disperse the raw products on the flat die equally. During rotating, the roller and flat die types solid stress and also fraction, which will certainly warm up the compression chamber to 80 ℃. In this condition, the materials become soften as well as simple to mold and mildew.



The down stress from the roller press the raw products into the holes on flat die, in which they are formed into round strips. The strips end up being longer and also much longer as the roller maintain pressing the raw products. When the strips appear from all-time low of the holes, there is a slicer cutting them off. Richi machinery cut strips fall down as well as discharge from the electrical outlet. These strips are what we call "wood pellets".



Flat die and also ring die pellet mill contrast

Flat die pellet machine appropriates for residence usage and small workshop production. It costs low. The size is little and also the manufacturing is relatively reduced. For big scale manufacturing, ring die pellet machine has more advantages. It has big production ability and also reduced power usage, however the size and also price is a lot larger. The significant difference between ring die and also flat die pellet machine are the shape of the dies and also the placement of rollers.



Ring die in pellet machine

Ring die is an annulus with numerous holes on it. It is constructed from carbon steel (alloy steel) and also stainless-steel, as well as processed by build and stamp, reducing, exploration and warmth treatment. The toughness of the ring die is influenced by the variety 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 typically made from high-carbon steel or cooled cast iron. It should has greater hardness than the ring die, to make sure that it can understand the 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 of the roller to grab the raw products.



Just how do the roller and also ring die work?


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



The raw products were first fed into the conditioner for blending. After that they are communicated to the compression chamber by a screw feeder. In the compression chamber, the rollers are still as well as the ring die rotates drive by the electric motor. As long as the raw materials are gotten by the ring die, they are squeezed right into the holes. The high temperature as well as stress trigger physical as well as chemical modifications to the raw products. When they are extruded out from the ring die, there are slicers that reduced them off. And also the pellets falls down and also venture out through the outlet.
