Pellet mill die and roller layout and manufacturer<br>
Roller and also die is the core part of the pellet machine They identifies the creating price and pellet quality. They are additionally the most wearable components. This article introduces the layout of roller as well as die in 2 sorts of pellet machine TICO is a specialist flat die pellet machine producer 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 lots of openings on it. It is made of ductile actors iron. After carburizing and relieving therapy, the solidity 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 as well as production demand, the thickness and also opening dimensions are different.



The functioning life of a flat die is 300-500 hours. When one side has actually broken, it can be utilized with the opposite. The length as well as dimension of the hole is developed based upon a great deal of experiments, so that it achieves the best compression ratio for 30 biomass materials.



The flat die need to be changed when it wears. It doesn't take much initiatives. Simply loosen the lock nuts on both sides, eliminate the upper chassis and also obtain the roller as well as flat die. richi pellet mill supplies superior spare parts for the pellet machine, consisting of roller and 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 cyndrical tubes with many skid-proof ace on its surface area. During functioning, the roller shaft revolves around the major shaft, and the rollers rotate around the major shaft at the same time. The sizes of the rollers differ with the production ability.



The firmness of rollers is lower than that of flat die, so that they reduce the endure flat die, and also prolong their functioning life. All rollers ought to have the same clearance with the flat die to achieve consistent stress. The clearance is in between 0.1-0.3 mm.



The roller adopts conical form to guarantee the revolving rate at the 2 ends coincide. This style can stay clear of slipping of the roller, decrease energy waste, as well as reduce the wear of flat die. Besides, it adopts an screw central stress modification tool. It allows you to readjust the clearance between roller and die, so as to adapt to various products and also make sure molding effect.



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

When the raw materials are fed into the pellet machine with the hopper. They fall on the flat die as well as roller. The roller revolves driven by the major shaft, and disperse the raw products on the flat die evenly. Throughout revolving, the roller and flat die forms solid pressure and also portion, which will heat up the compression chamber to 80 ℃. In this problem, the products end up being soften and simple to mold and mildew.



The downward stress from the roller squeeze the raw products into the holes on flat die, in which they are created into cylindrical strips. The strips come to be longer and also much longer as the roller keep squeezing 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 and release from the electrical outlet. These strips are what we call "wood pellets".



Apartment die and call die pellet mill contrast

Flat die pellet machine appropriates for home use as well as little workshop manufacturing. It sets you back reduced. The size is little and also the manufacturing is relatively reduced. For huge scale production, ring die pellet machine has even more benefits. It has large production capacity as well as reduced power usage, yet the dimension and also price is much larger. The major difference between ring die and also flat die pellet machine are the shape of the dies and also the position of rollers.



Ring die in pellet machine

Ring die is an annulus with many openings on it. It is made from carbon steel (alloy steel) and stainless-steel, and also refined by forge and also mark, cutting, boring and also warmth treatment. The toughness of the ring die is affected by the number of holes. The larger the size of openings, the less the number.



Rollers in ring die pellet machine

The rollers of ring die pellet machine are normally made of high-carbon steel or cooled actors iron. richi pellet machine ought to has greater firmness than the ring die, to ensure that it can recognize the very best compression effect and also uniform abrasion. The ideal clearance in between the rollers as well as ring die is 0.1-0.4 mm. There are axial grooves on the surface of the roller to get the raw products.




Exactly how do the roller and also ring die job?

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




The raw products were first fed right into the conditioner for blending. After that they are conveyed to the compression chamber by a screw feeder. In the compression chamber, the rollers are still and the ring die rotates drive by the electric motor. As long as the raw materials are gotten by the ring die, they are pressed right into the holes. The high temperature and pressure create physical as well as chemical modifications to the raw materials. 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 electrical outlet.
