Flat die in pellet machine.
In flat die pellet machine, the die is a disc with several holes on it. It is made of pliable actors iron. After carburizing as well as satiating therapy, the firmness is 55-60HRC. The size of the holes are from 2.5 mm to 10mm. One of the most popular dimensions are 6mm, 8mm and also 10mm. To adjust to different products and also production need, the density as well as hole dimensions are different.
The functioning life of a flat die is 300-500 hrs. When one side has worn out, it can be used with the opposite. The size as well as size of the hole is designed based on a multitude of experiments, so that it accomplishes the very best compression ratio for 30 biomass products.
The flat die need to be replaced when it wears out. It does not take much initiatives. Just loosen up hemp pellet machine on both sides, get rid of the upper chassis and obtain the roller as well as flat die. TICO provides premium extra components for the pellet machine, consisting of roller and also die.
Roller in flat die pellet machine.
In flat die pellet machine, the rollers are set up on the main shaft. 2 or even more rollers are connected by a roller shaft. The rollers are cylinders with several skid-proof ace on its surface. During working, the roller shaft revolves around the main shaft, as well as the rollers revolve around the major shaft at the same time. The diameters of the rollers vary with the production capability.
The firmness of rollers is lower than that of flat die, so that they decrease the wear on flat die, and extend their functioning life. All rollers need to have the exact same clearance with the flat die to attain consistent pressure. The clearance is between 0.1-0.3 mm.
The roller takes on conical form to make sure the rotating rate at the 2 ends coincide. This layout can avoid sliding of the roller, minimize power waste, and also reduce the wear of flat die. Besides, it takes on an screw central stress change tool. It enables you to adjust the clearance between roller and die, so as to adjust to different materials as well as guarantee molding result.
Just how do the roller as well as flat die job?
When the raw materials are fed into the pellet machine through the hopper. \extruder pellet machine\ fall on the flat die as well as roller. The roller turns driven by the main shaft, as well as distribute the raw materials on the flat die equally. During revolving, the roller as well as flat die kinds strong pressure and fraction, which will warm up the compression chamber to 80 ℃. In this problem, the products come to be soften and easy to mold and mildew.
The downward stress from the roller capture the raw materials right into the holes on flat die, in which they are created right into round strips. The strips become longer and much longer as the roller keep squeezing the raw products. When the strips appear from all-time low of the holes, there is a slicer reducing them off. The cut strips fall down as well as release from the electrical outlet. These strips are what we call "timber pellets".
Flat die and also sound die pellet mill contrast
Apartment die pellet machine is suitable for residence usage and also little workshop manufacturing. It sets you back low. The size is little and also the manufacturing is relatively reduced. For big range manufacturing, ring die pellet machine has more advantages. It has big production capability and low power intake, however the dimension as well as price is a lot larger. The significant difference between ring die and flat die pellet machine are the form of the dies and the position of rollers.
Ring die in pellet machine
Ring die is an annulus with numerous openings on it. It is constructed from carbon steel (alloy steel) and stainless steel, as well as refined by build and also mark, reducing, exploration as well as warmth treatment. The toughness of the ring die is affected by the variety of openings. The bigger the dimension of openings, the less the number.
Rollers in ring die pellet machine
The rollers of ring die pellet machine are usually constructed from high-carbon steel or cooled cast iron. It ought to has higher solidity than the ring die, to ensure that it can understand the most effective compression impact and also consistent abrasion. The ideal clearance 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.
How do the roller as well as ring die job?
In ring die pellet machine, the 2 rollers are installed inside the ring die. water ring pelletizer put pressure outward on the internal wall surface 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 grabbed by the ring die, they are squeezed right into the holes. The heat and also pressure trigger physical as well as chemical changes to the raw materials. When they are extruded out from the ring die, there are slicers that cut them off. As well as the pellets drops as well as go out via the outlet.
