Pellet mill die and also roller layout as well as maker<br>
Roller as well as 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 post introduces the layout of roller and also die in 2 kinds of pellet machine TICO is a specialist flat die pellet machine manufacturer in China. Richi machinery provide roller, flat die and also other extra parts for the pellet machine.



Apartment die in pellet machine.


In flat die pellet machine, the die is a disc with many holes on it. It is made of ductile cast iron. After carburizing and satiating treatment, the firmness is 55-60HRC. The size of the holes are from 2.5 mm to 10mm. One of the most prominent sizes are 6mm, 8mm and 10mm. To adjust to various materials as well as production need, the thickness and opening sizes are different.



The working life of a flat die is 300-500 hrs. When one side has actually worn out, it can be made use of with the opposite. The size and size of the hole is made based upon a lot of experiments, so that it achieves the best compression proportion for 30 biomass products.



The flat die need to be changed when it wears. It does not take much initiatives. Just loosen the lock nuts on both sides, remove the top chassis and also secure the roller and also flat die. TICO gives exceptional spare parts 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 main shaft. 2 or more rollers are attached by a roller shaft. The rollers are cylinders with many skid-proof ace on its surface area. During working, the roller shaft revolves around the main shaft, and also the rollers turn around the primary shaft at the same time. The diameters of the rollers vary with the manufacturing capacity.



The solidity of rollers is lower than that of flat die, so that they reduce the endure flat die, and also extend their working life. All rollers must have the very same clearance with the flat die to attain consistent pressure. The clearance is in between 0.1-0.3 mm.




The roller adopts conical shape to make sure the revolving speed at the 2 ends are the same. This design can prevent slipping of the roller, minimize power waste, and also minimize the wear of flat die. Besides, it takes on an screw central stress adjustment gadget. It allows you to readjust the clearance between roller as well as die, so as to adjust to different products and also guarantee molding effect.



How do the roller as well as flat die work?

When the raw products are fed into the pellet machine with the receptacle. They fall on the flat die and also roller. The roller turns driven by the main shaft, and disperse the raw materials on the flat die evenly. Throughout revolving, the roller as well as flat die kinds strong pressure and portion, which will certainly heat up the compression chamber to 80 ℃. In this problem, the products come to be soften and easy to mold and mildew.



The descending stress from the roller capture the raw materials right into the holes on flat die, in which they are developed right into round strips. The strips end up being longer as well as much longer as the roller keep pressing 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 and discharge from the outlet. These strips are what we call "wood pellets".



Apartment die as well as sound die pellet mill contrast

Flat die pellet machine appropriates for residence usage and tiny workshop manufacturing. It costs low. The dimension is little as well as the manufacturing is reasonably low. For big scale production, ring die pellet machine has more benefits. It has big manufacturing capability and also reduced power usage, but the dimension and expense is much bigger. The significant distinction between ring die and also flat die pellet machine are the shape of the dies as well as the position 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) as well as stainless steel, as well as processed by forge as well as stamp, cutting, exploration and heat therapy. The stamina of the ring die is affected by the variety of openings. 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 chilled cast iron. It needs to has higher hardness than the ring die, to make sure that it can recognize the very best compression impact as well as consistent abrasion. floating fish feed mill 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 materials.



Exactly how do the roller and also ring die job?

In ring die pellet machine, the 2 rollers are set up 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 mixing. 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 electrical motor. As long as the raw products are grabbed by the ring die, they are pressed right into the holes. The heat and pressure create physical and chemical adjustments to the raw materials. When they are extruded out from the ring die, there are slicers that cut them off. And the pellets falls down and also get out through the electrical outlet.
