Pellet mill die as well as roller layout and supplier<br>
Roller and also die is the core part of the pellet machine They determines the developing rate and pellet high quality. They are also one of the most wearable parts. This write-up introduces the style of roller as well as die in 2 kinds of pellet machine TICO is an expert flat die pellet machine supplier in China. We provide roller, flat die as well as other spare components for the pellet machine.



Flat die in pellet machine.


In flat die pellet machine, the die is a disc with numerous openings on it. It is made of pliable cast iron. After carburizing and satiating treatment, the solidity is 55-60HRC. richi pellet machine of the holes are from 2.5 mm to 10mm. One of the most popular dimensions are 6mm, 8mm as well as 10mm. To adjust to different materials and manufacturing need, the thickness as well as hole sizes are different.



The working life of a flat die is 300-500 hours. When one side has worn out, it can be utilized with the opposite. The size as well as dimension of the hole is created based upon a great deal of experiments, to ensure that it achieves the very best compression ratio for 30 biomass materials.



The flat die need to be changed when it wears. It doesn't take much efforts. Simply loosen the lock nuts on both sides, get rid of the upper chassis and take out the roller and flat die. TICO gives remarkable extra components for the pellet machine, consisting of 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 more rollers are attached by a roller shaft. The rollers are cylinders with several skid-proof ace on its surface area. Throughout working, the roller shaft turns around the main shaft, as well as the rollers revolve around the main shaft at the same time. The diameters of the rollers vary with the production capacity.



The firmness of rollers is less than that of flat die, so that they lower the wear on flat die, and also extend their functioning life. All rollers should have the same clearance with the flat die to accomplish consistent stress. The clearance is in between 0.1-0.3 mm.



The roller takes on conical shape to make certain the turning speed at the 2 ends coincide. This layout can prevent sliding of the roller, minimize energy waste, and also reduce the wear of flat die. Besides, it adopts an screw central stress change tool. It permits you to adjust the clearance between roller and die, so regarding adapt to various materials and also make certain molding effect.



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

When the raw materials are fed right into the pellet machine through the receptacle. They fall on the flat die and roller. The roller rotates driven by the primary shaft, as well as disperse the raw materials on the flat die evenly. During rotating, the roller as well as flat die kinds strong pressure and portion, which will certainly heat up the compression chamber to 80 ℃. In this condition, the materials come to be soften and very easy to mold.



The downward pressure from the roller capture the raw materials into the holes on flat die, in which they are developed right into cylindrical strips. The strips come to be much longer and much longer as the roller keep squeezing the raw products. When the strips appear from the bottom of the holes, there is a slicer cutting them off. The cut strips drop as well as discharge from the outlet. These strips are what we call "timber pellets".



Flat die as well as call die pellet mill comparison

Flat die pellet machine appropriates for residence usage as well as little workshop production. It costs low. The dimension is tiny as well as the manufacturing is reasonably reduced. For huge scale manufacturing, ring die pellet machine has even more benefits. It has big production capacity and also low power usage, however the size and price is a lot bigger. The major distinction between ring die as well as 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 lots of openings on it. richi pellet machine is constructed from carbon steel (alloy steel) and stainless-steel, and also refined by create and also stamp, cutting, drilling as well as warmth treatment. The stamina of the ring die is affected by the variety of holes. The bigger the dimension of holes, the much less the number.



Rollers in ring die pellet machine


The rollers of ring die pellet machine are normally made of high-carbon steel or chilled cast iron. It should has greater firmness than the ring die, to ensure that it can understand the very best compression effect and also uniform abrasion. The suitable clearance in between the rollers as well as ring die is 0.1-0.4 mm. There are axial grooves on the surface area of the roller to grab the raw products.



How do the roller and ring die job?

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



The raw materials were first fed right 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 grabbed by the ring die, they are squeezed right into the holes. The heat and also stress create physical and chemical changes to the raw materials. When they are extruded out from the ring die, there are slicers that reduced them off. As well as the pellets falls down as well as get out with the electrical outlet.
