Pellet mill die and also roller design and also manufacturer<br>
Roller as well as die is the core part of the pellet machine They identifies the creating price and pellet top quality. They are additionally one of the most wearable parts. This article introduces the layout of roller and die in 2 sorts of pellet machine TICO is an expert flat die pellet machine producer in China. We supply roller, flat die as well as various other extra components for the pellet machine.



Apartment die in pellet machine.


In flat die pellet machine, the die is a disc with lots of openings on it. It is made from ductile actors iron. After carburizing and satiating therapy, the firmness is 55-60HRC. The dimension of the holes are from 2.5 mm to 10mm. One of the most popular sizes are 6mm, 8mm and 10mm. To adapt to different materials and production requirement, the density and hole sizes are different.



The functioning life of a flat die is 300-500 hrs. When one side has broken, it can be utilized with the opposite. manual fish feed making machine and also dimension of the hole is created based upon a great deal of experiments, to ensure that it achieves the best compression ratio for 30 biomass products.



The flat die requirement to be changed when it wears. It does not take much efforts. Simply loosen up the lock nuts on both sides, get rid of the upper chassis and also obtain the roller and flat die. TICO gives remarkable extra parts for the pellet machine, including roller and die.



Roller in flat die pellet machine.

In flat die pellet machine, the rollers are set up on the major shaft. 2 or more rollers are connected by a roller shaft. The rollers are cylinders with many skid-proof ace on its surface. During working, the roller shaft rotates around the main shaft, and also the rollers revolve around the major shaft at the same time. The diameters of the rollers vary with the production capacity.



The solidity of rollers is lower than that of flat die, so that they reduce the endure flat die, and lengthen their functioning life. All rollers should have the same clearance with the flat die to accomplish uniform pressure. The clearance is between 0.1-0.3 mm.



The roller embraces tapered form to ensure the turning rate at the 2 ends are the same. This design can stay clear of slipping of the roller, lower power waste, as well as reduce the wear of flat die. Besides, sawdust pellet mill takes on an screw main pressure modification device. It allows you to readjust the clearance in between roller and also die, so regarding adapt to various products and guarantee molding effect.



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

When the raw materials are fed into the pellet machine through the receptacle. They fall on the flat die and roller. The roller revolves driven by the main shaft, and also disperse the raw products on the flat die evenly. During revolving, the roller and flat die forms strong stress as well as fraction, which will heat up the compression chamber to 80 ℃. In this problem, the materials become soften and very easy to mold and mildew.



The downward pressure from the roller capture the raw products right into the holes on flat die, in which they are developed right into cylindrical strips. The strips become longer and also much longer as the roller maintain squeezing the raw materials. When the strips come out from the bottom of the holes, there is a slicer cutting them off. The cut strips fall down and release from the outlet. These strips are what we call "wood pellets".



Flat die and sound die pellet mill comparison

Apartment die pellet machine appropriates for house usage as well as small workshop manufacturing. It sets you back reduced. The size is little and also the production is relatively low. For big scale production, ring die pellet machine has even more benefits. It has large manufacturing capacity and also low power intake, however the size and also expense is much larger. The major distinction between ring die as well as flat die pellet machine are the form of the dies as well as the setting 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, and processed by build and stamp, cutting, exploration and also warmth therapy. The toughness of the ring die is influenced by the number of openings. The larger the dimension of openings, the much less the number.



Rollers in ring die pellet machine

The rollers of ring die pellet machine are usually constructed from high-carbon steel or chilled actors iron. It needs to has higher solidity than the ring die, to ensure that it can realize the very best compression impact as well as uniform abrasion. The appropriate clearance 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 materials.



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

In ring die pellet machine, the 2 rollers are set up inside the ring die. The roller placed pressure outward on the internal wall surface of the ring die.



The raw materials were first fed into the conditioner for mixing. After that they are shared to the compression chamber by a screw feeder. In the compression chamber, the rollers are still and also the ring die rotates drive by the electric motor. As long as the raw materials are grabbed by the ring die, they are squeezed right into the holes. The heat and pressure create physical as well as chemical modifications to the raw products. When they are extruded out from the ring die, there are slicers that reduced them off. And also the pellets drops and also get out via the outlet.
