Pellet mill die as well as roller layout and also producer<br>
Roller and also die is the core part of the pellet machine They determines the forming rate and pellet top quality. They are additionally one of the most wearable components. This article presents the design of roller and die in 2 types of pellet machine TICO is a specialist flat die pellet machine producer in China. We supply roller, flat die and various 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 from ductile cast iron. After carburizing as well as satiating therapy, the hardness is 55-60HRC. The size of the holes are from 2.5 mm to 10mm. One of the most popular sizes are 6mm, 8mm as well as 10mm. To adjust to different materials and also production demand, the density and also opening dimensions are different.



The functioning life of a flat die is 300-500 hrs. When one side has actually worn, it can be used with the other side. The size as well as dimension of the hole is created based on a multitude of experiments, to ensure that it attains the very best compression proportion for 30 biomass products.



The flat die requirement to be changed when it wears out. It doesn't take much initiatives. Simply loosen up the lock nuts on both sides, get rid of the upper chassis and obtain the roller and flat die. TICO provides superior 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 mounted on the primary shaft. 2 or even more rollers are connected by a roller shaft. The rollers are cyndrical tubes with many skid-proof ace on its surface. Throughout functioning, the roller shaft rotates around the main shaft, and the rollers revolve around the major shaft at the same time. The diameters of the rollers differ with the manufacturing capability.



The solidity of rollers is lower than that of flat die, to make sure that they lower the wear on flat die, as well as prolong their working life. All rollers should have the same clearance with the flat die to achieve uniform pressure. The clearance is in between 0.1-0.3 mm.



The roller takes on tapered shape to make sure the rotating speed at the 2 ends are the same. richi pellet machine can stay clear of slipping of the roller, decrease power waste, and also reduce the wear of flat die. Besides, it adopts an screw main pressure adjustment device. It permits you to adjust the clearance in between roller as well as die, so regarding adapt to various materials as well as guarantee molding result.



Exactly how do the roller and also flat die work?

When the raw products are fed right into the pellet machine with the receptacle. They fall on the flat die and also roller. The roller rotates driven by the primary shaft, as well as disperse the raw materials on the flat die uniformly. Throughout rotating, the roller as well as flat die kinds strong pressure and fraction, which will certainly heat up the compression chamber to 80 ℃. In this condition, the materials come to be soften as well as simple to mold and mildew.



The downward pressure from the roller squeeze the raw products right into the holes on flat die, in which they are created into round strips. The strips become much longer and also longer as the roller keep 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 fall down and also discharge from the electrical outlet. These strips are what we call "wood pellets".



Apartment die and call die pellet mill contrast

Flat die pellet machine appropriates for home use and also tiny workshop production. It costs low. The dimension is tiny as well as the production is relatively low. For huge range production, ring die pellet machine has more benefits. It has huge manufacturing ability and low power intake, yet the dimension as well as cost is a lot bigger. The major distinction between ring die as well as flat die pellet machine are the form of the dies as well as the position of rollers.



Ring die in pellet machine

Ring die is an annulus with several holes on it. It is made from carbon steel (alloy steel) and also stainless steel, as well as processed by create as well as mark, cutting, boring as well as warm treatment. Richi machinery of the ring die is influenced by the variety of holes. The larger the size of holes, the much less the number.



Rollers in ring die pellet machine

The rollers of ring die pellet machine are usually made from high-carbon steel or cooled cast iron. It ought to has higher solidity than the ring die, so that it can understand the most effective compression impact as well as consistent abrasion. The appropriate clearance between the rollers and ring die is 0.1-0.4 mm. There are axial grooves on the surface area of the roller to get hold of the raw products.



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

In ring die pellet machine, the 2 rollers are set up inside the ring die. The roller put stress external on the inner wall of the ring die.




The raw materials were first fed right into the conditioner for blending. After that they are conveyed 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 electrical motor. As long as the raw materials are ordered by the ring die, they are pressed right into the holes. The heat as well as pressure trigger physical as well as chemical adjustments to the raw materials. When they are extruded out from the ring die, there are slicers that reduced them off. And the pellets falls down and also get out through the outlet.
