Pellet mill die and roller layout and also supplier<br>
Roller and 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 write-up presents the layout of roller as well as die in 2 types of pellet machine TICO is an expert flat die pellet machine producer in China. We supply roller, flat die as well as other extra components for the pellet machine.



Flat die in pellet machine.

In flat die pellet machine, the die is a disc with many holes on it. It is made of ductile actors 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. One of the most prominent sizes are 6mm, 8mm and also 10mm. To adjust to various materials and manufacturing demand, the thickness and hole dimensions are different.



The working life of a flat die is 300-500 hrs. When one side has broken, it can be made use of with the other side. The length and also dimension of the hole is designed based on a great deal of experiments, to ensure that it achieves the very best compression ratio for 30 biomass products.



The flat die demand to be changed when it wears out. It does not take much initiatives. Simply loosen the lock nuts on both sides, get rid of the top framework and also secure the roller as well as flat die. TICO provides premium extra parts for the pellet machine, consisting of roller as well as die.




Roller in flat die pellet machine.

In flat die pellet machine, the rollers are installed on the major shaft. 2 or even more rollers are connected by a roller shaft. The rollers are cylinders with many skid-proof ace on its surface area. During functioning, the roller shaft revolves around the main shaft, as well as the rollers rotate around the primary shaft at the same time. The sizes of the rollers vary with the production ability.



The hardness of rollers is less than that of flat die, to make sure that they reduce the endure flat die, and extend their working life. All rollers should have the very same clearance with the flat die to achieve consistent pressure. The clearance is between 0.1-0.3 mm.



The roller adopts tapered shape to make certain the rotating speed at the 2 ends coincide. This layout can stay clear of sliding of the roller, minimize energy waste, and decrease the wear of flat die. Besides, it adopts an screw main stress adjustment tool. It enables you to adjust the clearance between roller as well as die, so as to adjust to various materials as well as guarantee molding impact.



How do the roller and also flat die job?

When the raw products are fed into the pellet machine through the hopper. They fall on the flat die and also roller. The roller turns driven by the major shaft, and distribute the raw products on the flat die evenly. During revolving, the roller and flat die forms solid pressure and portion, which will heat up the compression chamber to 80 ℃. In this problem, the products come to be soften and simple to mold and mildew.



The descending pressure from the roller squeeze the raw materials right into the holes on flat die, in which they are formed right into round strips. The strips come to be longer as well as longer as the roller keep squeezing the raw materials. When the strips appear from the bottom of the holes, there is a slicer reducing them off. hammer mill for wood pellets cut strips drop and also discharge from the outlet. These strips are what we call "timber pellets".



Flat die and sound die pellet mill comparison

Flat die pellet machine appropriates for residence usage as well as small workshop manufacturing. It sets you back low. The size is tiny as well as the production is fairly reduced. For big range production, ring die pellet machine has even more benefits. It has huge production capability and also reduced power usage, yet the dimension as well as cost is much bigger. The major distinction in between ring die as well as flat die pellet machine are the form of the dies and also the placement of rollers.



Ring die in pellet machine

Ring die is an annulus with lots of openings on it. It is made of carbon steel (alloy steel) and stainless steel, as well as refined by build as well as mark, reducing, exploration and warmth therapy. The stamina of the ring die is influenced by the variety of openings. The larger the dimension of holes, the less the number.



Rollers in ring die pellet machine

The rollers of ring die pellet machine are normally constructed from high-carbon steel or cooled actors iron. It needs to has higher firmness than the ring die, to make sure that it can recognize the best compression result as well as uniform abrasion. The appropriate clearance 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 get the raw materials.



Just how do the roller and ring die job?

In ring die pellet machine, the 2 rollers are installed inside the ring die. The roller put pressure external on the inner wall surface of the ring die.




The raw products were first fed into the conditioner for blending. Then they are conveyed to the compression chamber by a screw feeder. In granule extruder , the rollers are still as well as the ring die rotates drive by the electric motor. As long as the raw products are grabbed by the ring die, they are pressed right into the holes. The heat and pressure create physical and also 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 via the outlet.
