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




Apartment die in pellet machine.

In flat die pellet machine, the die is a disc with lots of holes on it. It is constructed from pliable actors iron. After carburizing and also satiating therapy, the firmness is 55-60HRC. The size of the holes are from 2.5 mm to 10mm. The most preferred sizes are 6mm, 8mm as well as 10mm. To adjust to various products and also manufacturing requirement, the thickness and also opening sizes are different.



The working life of a flat die is 300-500 hrs. When click to read has worn, it can be used with the opposite. The length and size of the hole is designed based upon a great deal of experiments, to ensure that it attains the most effective compression proportion for 30 biomass materials.



The flat die requirement to be changed when it wears. It does not take much efforts. Simply loosen up the lock nuts on both sides, remove the upper chassis and take out the roller and also flat die. TICO gives remarkable extra parts for the pellet machine, consisting of roller and die.



Roller in flat die pellet machine.

In flat die pellet machine, the rollers are set up on the primary shaft. 2 or even more rollers are linked by a roller shaft. The rollers are cyndrical tubes with lots of skid-proof ace on its surface. During functioning, the roller shaft revolves around the primary shaft, and also the rollers rotate around the primary shaft at the same time. The diameters of the rollers differ with the production ability.



The solidity of rollers is lower than that of flat die, to ensure that they reduce the endure flat die, and extend their functioning life. All rollers need to have the same clearance with the flat die to accomplish uniform stress. The clearance is between 0.1-0.3 mm.



The roller adopts tapered form to guarantee the rotating rate at the 2 ends coincide. This layout can stay clear of slipping of the roller, reduce power waste, and also minimize the wear of flat die. Besides, it adopts an screw central stress change gadget. It allows you to change the clearance in between roller and die, so as to adapt to different products and ensure molding impact.



Just how do the roller and also flat die work?

When the raw products are fed into the pellet machine through the hopper. They fall on the flat die and roller. The roller revolves driven by the main shaft, as well as distribute the raw products on the flat die uniformly. During turning, the roller as well as flat die kinds solid pressure and portion, which will certainly heat up the compression chamber to 80 ℃. In this condition, the products end up being soften as well as very easy to mold.



The descending pressure from the roller capture the raw products right into the holes on flat die, in which they are created into cylindrical strips. The strips come to be longer and longer as the roller maintain squeezing the raw materials. When the strips appear 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 "timber pellets".



Flat die and ring die pellet mill comparison


Flat die pellet machine is suitable for house use and also tiny workshop manufacturing. It sets you back low. The size is little and also the production is reasonably reduced. For large range production, ring die pellet machine has more benefits. It has large production capacity and also reduced power consumption, but the size and also cost is much bigger. The major difference between ring die as well as flat die pellet machine are the form of the dies as well as the setting of rollers.



Ring die in pellet machine

Ring die is an annulus with many holes on it. It is made of carbon steel (alloy steel) and stainless-steel, as well as processed by create and also mark, reducing, drilling and also heat therapy. The strength of the ring die is influenced by the number of holes. The bigger the dimension of openings, the less the number.



Rollers in ring die pellet machine

The rollers of ring die pellet machine are generally made of high-carbon steel or chilled cast iron. It needs to has higher firmness than the ring die, so that it can realize the very best compression result as well as uniform abrasion. The suitable clearance in between the rollers and also ring die is 0.1-0.4 mm. There are axial grooves on the surface area of the roller to order the raw products.



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 placed pressure external 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 the ring die rotates drive by the electrical motor. As long as the raw materials are gotten by the ring die, they are squeezed into the holes. die for pellet mill and stress create physical and also chemical adjustments to the raw products. When they are extruded out from the ring die, there are slicers that cut them off. And the pellets falls down as well as get out with the outlet.
