Pellet mill die as well as roller design and maker<br>
Roller as well as die is the core part of the pellet machine They figures out the developing rate as well as pellet top quality. They are also one of the most wearable components. This write-up introduces the style of roller and also die in 2 kinds of pellet machine TICO is a specialist flat die pellet machine supplier in China. pellet making machine for cattle feed supply roller, flat die and also various other extra components for the pellet machine.



Flat die in pellet machine.

In flat die pellet machine, the die is a disc with lots of openings on it. It is made from pliable cast iron. After carburizing and appeasing therapy, the hardness is 55-60HRC. The dimension of the holes are from 2.5 mm to 10mm. The most popular sizes are 6mm, 8mm as well as 10mm. To adjust to various materials and also production need, the density and opening dimensions are various.



The working life of a flat die is 300-500 hours. When one side has worn out, it can be made use of with the opposite. The length and dimension of the hole is designed based on a multitude of experiments, to ensure that it achieves the very best compression proportion for 30 biomass materials.



The flat die requirement to be replaced when it wears out. It does not take much efforts. Simply loosen up the lock nuts on both sides, get rid of the top framework and secure the roller as well as flat die. TICO offers 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 mounted on the primary shaft. 2 or even more rollers are attached by a roller shaft. The rollers are cylinders with several skid-proof ace on its surface area. During working, the roller shaft rotates around the primary shaft, and the rollers rotate around the main shaft at the same time. The diameters of the rollers differ with the manufacturing capacity.



The hardness of rollers is less than that of flat die, to ensure that they lower the endure flat die, as well as extend their functioning life. All rollers ought to have the very same clearance with the flat die to achieve uniform pressure. The clearance is in between 0.1-0.3 mm.



The roller adopts conical shape to guarantee the turning rate at the 2 ends are the same. This style can prevent sliding of the roller, lower power waste, and also decrease the wear of flat die. Besides, it adopts an screw central stress change tool. It allows you to change the clearance in between roller and also die, so as to adapt to different materials as well as make certain molding impact.



Exactly how do the roller and also flat die work?

When the raw products are fed right into the pellet machine through the hopper. They fall on the flat die as well as roller. The roller turns driven by the major shaft, as well as disperse the raw materials on the flat die evenly. Throughout rotating, the roller as well as flat die kinds solid stress and portion, which will heat up the compression chamber to 80 ℃. In this condition, the materials end up being soften and simple to mold.



The downward pressure from the roller squeeze the raw materials into the holes on flat die, in which they are created right into round strips. The strips end up being longer as well as longer as the roller keep pressing the raw products. When the strips appear from the bottom of the holes, there is a slicer cutting them off. The cut strips drop and release from the electrical outlet. These strips are what we call "timber pellets".



Flat die as well as sound die pellet mill comparison

Apartment die pellet machine is suitable for home use as well as little workshop production. It sets you back low. The dimension is small and the production is fairly reduced. For large range production, ring die pellet machine has even more benefits. It has large production ability as well as reduced power intake, yet the size and cost is a lot bigger. The significant difference between ring die and flat die pellet machine are the form of the dies and the setting of rollers.



Ring die in pellet machine

Ring die is an annulus with lots of openings on it. It is constructed from carbon steel (alloy steel) and stainless-steel, and processed by forge and stamp, reducing, drilling and warmth treatment. The toughness of the ring die is affected by the variety of holes. The larger the dimension of holes, the less the number.



Rollers in ring die pellet machine

The rollers of ring die pellet machine are typically made from high-carbon steel or chilled cast iron. It needs to has greater firmness than the ring die, to ensure that it can recognize the very best compression result and consistent abrasion. The ideal clearance between the rollers and ring die is 0.1-0.4 mm. There are axial grooves on the surface of the roller to get the raw products.




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 put stress outside on the internal wall of the ring die.



The raw materials were first fed right into the conditioner for blending. Then they are shared to the compression chamber by a screw feeder. In the compression chamber, the rollers are still and the ring die rotates drive by the electrical motor. As link as the raw products are ordered by the ring die, they are squeezed right into the holes. The high temperature and also pressure trigger physical and chemical adjustments to the raw products. 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 get out with the electrical outlet.
