Pellet mill die and also roller style as well as supplier<br>
Roller and die is the core part of the pellet machine They identifies the developing rate as well as pellet quality. They are additionally the most wearable parts. richi pellet introduces the design of roller as well as die in 2 types of pellet machine TICO is a professional flat die pellet machine maker in China. We provide roller, flat die and various other extra components for the pellet machine.



Apartment die in pellet machine.

In flat die pellet machine, the die is a disc with several holes on it. It is made of ductile actors iron. After carburizing and appeasing treatment, the hardness is 55-60HRC. The size 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 products and also manufacturing need, the thickness as well as hole dimensions are various.



The functioning life of a flat die is 300-500 hrs. When one side has broken, it can be utilized with the other side. see this website as well as dimension of the hole is designed based on a great deal of experiments, to make sure that it attains the very best compression ratio for 30 biomass products.



The flat die need to be changed when it wears out. It doesn't take much initiatives. Just loosen the lock nuts on both sides, eliminate the top chassis and also obtain the roller and flat die. TICO offers exceptional extra components for the pellet machine, including roller as well as die.



Roller in flat die pellet machine.

In flat die pellet machine, the rollers are mounted on the major shaft. 2 or more rollers are attached by a roller shaft. The rollers are cyndrical tubes with many skid-proof ace on its surface. During working, the roller shaft revolves around the major shaft, and also the rollers revolve around the main shaft at the same time. The sizes of the rollers vary with the manufacturing ability.



The solidity 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 very same clearance with the flat die to achieve consistent stress. The clearance is in between 0.1-0.3 mm.



The roller takes on conical form to make sure the rotating speed at the 2 ends coincide. This layout can stay clear of sliding of the roller, lower energy waste, as well as reduce the wear of flat die. Besides, it takes on an screw main stress modification tool. It allows you to adjust the clearance between roller and also die, so regarding adapt to different products as well as guarantee molding impact.



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

When the raw materials are fed right into the pellet machine via the receptacle. They fall on the flat die and roller. The roller revolves driven by the primary shaft, and disperse the raw products on the flat die evenly. Throughout rotating, the roller as well as flat die kinds strong stress and fraction, which will certainly warm up the compression chamber to 80 ℃. In this condition, the products end up being soften as well as very easy to mold and mildew.



The downward pressure from the roller squeeze the raw products into the holes on flat die, in which they are developed into cylindrical strips. The strips come to be much longer and also much longer as the roller maintain pressing the raw products. When the strips come out from the bottom of the holes, there is a slicer reducing 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

Flat die pellet machine appropriates for house usage and tiny workshop production. It costs low. The dimension is little and also the manufacturing is relatively reduced. For huge range production, ring die pellet machine has more benefits. It has large manufacturing capacity and also low power intake, however the dimension and also expense is a lot bigger. The significant distinction between ring die as well as flat die pellet machine are the shape of the dies as well as the placement of rollers.



Ring die in pellet machine

Ring die is an annulus with numerous openings on it. It is made of carbon steel (alloy steel) as well as stainless-steel, and also processed by build and also mark, reducing, boring and also heat therapy. The toughness of the ring die is affected by the number of holes. The larger the dimension of holes, the much less the number.




Rollers in ring die pellet machine

The rollers of ring die pellet machine are generally made from high-carbon steel or cooled cast iron. It needs to has higher firmness than the ring die, so that it can recognize the most effective compression impact and also uniform abrasion. The appropriate clearance between the rollers and also ring die is 0.1-0.4 mm. There are axial grooves on the surface area of the roller to get hold of the raw products.



How do the roller as well as ring die work?


In ring die pellet machine, the 2 rollers are installed inside the ring die. Richi machinery put pressure outward on the inner wall of the ring die.



The raw materials 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 as well as 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 and stress cause physical and chemical modifications to the raw materials. When they are extruded out from the ring die, there are slicers that cut them off. And the pellets drops as well as go out through the electrical outlet.
