Pellet mill die and also roller design as well as manufacturer<br>
Roller and die is the core part of the pellet machine They determines the creating rate and also pellet high quality. They are also the most wearable components. This article presents the design of roller and die in 2 sorts of pellet machine TICO is a specialist flat die pellet machine manufacturer in China. We provide roller, flat die and various other extra parts for the pellet machine.



Flat die in pellet machine.


In flat die pellet machine, the die is a disc with numerous holes on it. It is made from pliable cast iron. After carburizing as well as relieving therapy, the firmness is 55-60HRC. The size of the holes are from 2.5 mm to 10mm. The most preferred dimensions are 6mm, 8mm and 10mm. To adapt to different products and also manufacturing need, the thickness and also opening dimensions are different.



The functioning life of a flat die is 300-500 hours. When one side has worn out, it can be utilized with the opposite side. The length and also size of the hole is designed based on a lot of experiments, to ensure that it attains the best compression proportion for 30 biomass products.



The flat die requirement to be replaced when it wears out. It doesn't take much initiatives. Simply loosen the lock nuts on both sides, eliminate the upper framework and also secure the roller as well as flat die. TICO provides superior spare parts 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 more rollers are attached by a roller shaft. The rollers are cylinders with numerous skid-proof ace on its surface area. During functioning, the roller shaft rotates around the main shaft, and the rollers turn around the primary shaft at the same time. The sizes of the rollers vary with the manufacturing ability.



The solidity of rollers is less than that of flat die, to make sure that they lower the endure flat die, and also prolong their functioning life. All rollers must have the same clearance with the flat die to achieve uniform stress. The clearance is between 0.1-0.3 mm.



The roller takes on conical shape to guarantee the rotating speed at the 2 ends coincide. This style can stay clear of slipping of the roller, lower power waste, and also minimize the wear of flat die. Besides, it embraces an screw central pressure modification gadget. It enables you to change the clearance between roller and also die, so regarding adjust to various materials and also make certain molding effect.



Exactly how do the roller and flat die work?

When the raw products are fed into the pellet machine with the hopper. They fall on the flat die and also roller. The roller turns driven by the main shaft, as well as distribute the raw products on the flat die uniformly. Throughout rotating, animal feed pellet machine manufacturers and also flat die kinds solid stress as well as fraction, which will heat up the compression chamber to 80 ℃. In this condition, the products come to be soften as well as simple to mold.




The descending stress from the roller squeeze the raw products right into the holes on flat die, in which they are created right into round strips. The strips come to be longer and longer as the roller maintain squeezing the raw materials. When the strips come out from all-time low of the holes, there is a slicer cutting them off. The cut strips drop and also release from the outlet. These strips are what we call "timber pellets".



Apartment die as well as ring die pellet mill comparison

Flat die pellet machine is suitable for home use and little workshop production. It costs low. The size is small as well as the manufacturing is reasonably reduced. For big range manufacturing, ring die pellet machine has even more advantages. It has big manufacturing ability as well as low power intake, however the size and expense is a lot larger. The significant difference in between ring die as well as flat die pellet machine are the shape of the dies as well as the position of rollers.



Ring die in pellet machine

Ring die is an annulus with numerous holes on it. It is made of carbon steel (alloy steel) and stainless steel, as well as refined by create as well as mark, reducing, exploration and warmth treatment. The toughness of the ring die is affected by the variety of openings. The bigger the size of openings, the much less the number.



Rollers in ring die pellet machine

The rollers of ring die pellet machine are typically constructed from high-carbon steel or chilled cast iron. It ought to has greater firmness than the ring die, to ensure that it can recognize the best compression result and uniform abrasion. The appropriate clearance in between the rollers and also ring die is 0.1-0.4 mm. There are axial grooves on the surface of the roller to order 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 outward on the internal wall surface of the ring die.



The raw products were first fed right into the conditioner for blending. 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 products are grabbed by the ring die, they are pressed into the holes. The heat as well as stress create physical as well as chemical modifications to the raw materials. When they are extruded out from the ring die, there are slicers that reduced them off. As well as richi pellet machine and also get out via the outlet.
