Flat die in pellet machine.
In flat die pellet machine, the die is a disc with lots of holes on it. It is made from ductile cast iron. After carburizing and also appeasing treatment, the hardness is 55-60HRC. The dimension of the holes are from 2.5 mm to 10mm. One of the most prominent sizes are 6mm, 8mm as well as 10mm. To adjust to various materials and also manufacturing demand, the thickness as well as opening sizes are various.
The working life of a flat die is 300-500 hrs. When one side has worn, it can be made use of with the opposite side. The length and also dimension of the hole is created based on a multitude of experiments, so that it achieves the very best compression proportion for 30 biomass materials.
The flat die demand to be replaced when it wears. It doesn't take much efforts. Just loosen the lock nuts on both sides, remove the upper framework and also secure the roller as well as flat die. TICO provides remarkable spare components for the pellet machine, consisting of roller and die.
Roller in flat die pellet machine.
In flat die pellet machine, the rollers are installed on the main shaft. 2 or more rollers are linked by a roller shaft. The rollers are cylinders with many skid-proof ace on its surface. During amandus kahl pellet press , the roller shaft turns around the main shaft, and the rollers revolve around the primary shaft at the same time. The sizes of the rollers vary with the production ability.
The firmness of rollers is lower than that of flat die, so that they lower the wear on flat die, as well as lengthen their functioning life. All rollers need to have the very same clearance with the flat die to attain uniform stress. The clearance is in between 0.1-0.3 mm.
The roller adopts conical shape to make certain the turning speed at the 2 ends coincide. This style can avoid slipping of the roller, lower energy waste, and also decrease the wear of flat die. Besides, it takes on an screw main pressure adjustment tool. It enables you to change the clearance between roller and also die, so regarding adjust to various products as well as make sure molding impact.
Just how do the roller and also flat die work?
When the raw materials are fed into the pellet machine via the receptacle. They fall on the flat die and also roller. The roller revolves driven by the primary shaft, and also distribute the raw products on the flat die uniformly. During revolving, the roller as well as flat die types strong stress and fraction, which will heat up the compression chamber to 80 . In this condition, the products come to be soften and very easy to mold.
The descending stress from the roller squeeze the raw products right into the holes on flat die, in which they are formed right into round strips. The strips come to be much longer and also longer as the roller maintain pressing the raw materials. When the strips come out from the bottom of the holes, there is a slicer cutting them off. The cut strips drop as well as release from the electrical outlet. These strips are what we call "timber pellets".
Apartment die and call die pellet mill comparison
Flat die pellet machine appropriates for residence use and also little workshop production. It sets you back reduced. The size is little and also the manufacturing is reasonably reduced. For big scale production, ring die pellet machine has more benefits. It has big production capacity and also reduced power intake, yet the size and also price is much larger. The significant distinction between ring die and also flat die pellet machine are the form of the dies as well as the placement of rollers.
Ring die in pellet machine
Ring die is an annulus with several openings on it. It is made of carbon steel (alloy steel) and also stainless-steel, and processed by build and mark, reducing, boring as well as heat therapy. The stamina of the ring die is affected by the variety of openings. pellet grinder machine 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 chilled actors iron. It must has greater firmness than the ring die, to ensure that it can recognize the most effective compression result as well as 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 of the roller to get the raw materials.
How do the roller as well as ring die job?
In ring die pellet machine, the 2 rollers are mounted inside the ring die. The roller placed pressure exterior on the internal wall surface of the ring die.
The raw products were first fed into the conditioner for mixing. 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 right into the holes. The high temperature 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 falls down and venture out through the electrical outlet.
