Pellet mill die and also roller layout and also producer<br>
Roller and also die is the core part of the pellet machine They determines the forming rate and also pellet high quality. They are also one of the most wearable components. This post introduces the design of roller and die in 2 kinds of pellet machine TICO is an expert flat die pellet machine supplier in China. We provide 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 numerous holes on it. It is made from pliable cast iron. After carburizing and rice husk pellet machine , the hardness 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 different materials and also production need, the density as well as opening sizes are different.



The functioning life of a flat die is 300-500 hrs. When one side has worn, it can be utilized with the opposite side. The length as well as size of the hole is made based upon a large number of experiments, so that it attains the best compression ratio for 30 biomass products.



The flat die demand to be replaced when it breaks. It doesn't take much efforts. Simply loosen the lock nuts on both sides, remove the top framework and get the roller as well as flat die. TICO offers superior spare 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 installed on the major shaft. 2 or even more rollers are connected by a roller shaft. The rollers are cyndrical tubes with numerous skid-proof ace on its surface area. During working, the roller shaft revolves around the main shaft, and the rollers turn around the major shaft at the same time. The sizes of the rollers vary with the production capacity.



The solidity of rollers is lower than that of flat die, to ensure that they minimize the wear on flat die, and extend their working life. All rollers need to have the exact same clearance with the flat die to achieve uniform pressure. The clearance is between 0.1-0.3 mm.




The roller takes on tapered shape to ensure the revolving speed at the 2 ends coincide. hay pellet machine for sale can prevent sliding of the roller, lower power waste, as well as reduce the wear of flat die. Besides, it embraces an screw main stress change gadget. It permits you to readjust the clearance between roller and die, so as to adapt to various materials as well as guarantee molding impact.



How do the roller as well as flat die work?

When the raw products are fed right into the pellet machine through the receptacle. They fall on the flat die and also roller. The roller rotates driven by the main shaft, as well as distribute the raw materials on the flat die uniformly. Throughout rotating, the roller and also flat die forms solid stress as well as fraction, which will certainly warm up the compression chamber to 80 ℃. In this problem, the products become soften and very easy to mold.



The down pressure from the roller press the raw materials right into the holes on flat die, in which they are created right into cylindrical strips. The strips end up being much longer as well as much longer as the roller keep squeezing the raw materials. When the strips appear from the bottom of the holes, there is a slicer reducing them off. The cut strips drop and also release from the outlet. These strips are what we call "timber pellets".



Flat die as well as ring die pellet mill comparison

Apartment die pellet machine appropriates for residence usage as well as small workshop production. It sets you back reduced. The size is tiny and the production is reasonably reduced. For huge range production, ring die pellet machine has more advantages. It has big manufacturing ability and also low power intake, however the size and also expense is much bigger. The significant distinction between ring die and flat die pellet machine are the shape of the dies and also the setting of rollers.



Ring die in pellet machine

Ring die is an annulus with lots of openings on it. It is made of carbon steel (alloy steel) and stainless-steel, and also refined by create and also stamp, cutting, drilling as well as warmth therapy. The stamina of the ring die is affected by the number of holes. The bigger the size of holes, 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 actors iron. It ought to has greater hardness than the ring die, to make sure that it can understand the best compression result and uniform abrasion. The appropriate clearance in between the rollers and also ring die is 0.1-0.4 mm. There are axial grooves on the surface of the roller to get hold of the raw materials.



Just how do the roller as well as ring die job?

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



The raw materials were first fed right 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 and the ring die rotates drive by the electric motor. As long as the raw products are gotten by the ring die, they are pressed into the holes. The heat and pressure create physical and also chemical adjustments to the raw products. When they are extruded out from the ring die, there are slicers that reduced them off. As well as the pellets drops and venture out via the outlet.
