Pellet mill die and roller style as well as manufacturer<br>
Roller as well as die is the core part of the pellet machine They identifies the developing rate and also pellet top quality. They are also the most wearable parts. This short article introduces the layout of roller and die in 2 kinds of pellet machine TICO is a professional flat die pellet machine manufacturer in China. We supply roller, flat die and also 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 openings on it. It is made of ductile cast iron. After carburizing and also satiating therapy, the firmness is 55-60HRC. The size of the holes are from 2.5 mm to 10mm. One of the most preferred dimensions are 6mm, 8mm and also 10mm. To adjust to various products and production need, the density as well as hole sizes are various.




The working life of a flat die is 300-500 hrs. When one side has actually worn out, it can be made use of with the opposite side. The size and size of the hole is made based on a multitude of experiments, to ensure that it accomplishes the most effective compression ratio for 30 biomass products.



The flat die requirement to be changed when it wears. It doesn't take much efforts. Simply loosen up the lock nuts on both sides, get rid of the upper framework as well as get the roller as well as flat die. TICO supplies superior spare components 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 set up on the main shaft. 2 or more rollers are linked by a roller shaft. The rollers are cyndrical tubes with numerous skid-proof ace on its surface. During working, the roller shaft revolves around the primary shaft, and also the rollers turn around the primary shaft at the same time. The sizes of the rollers vary with the manufacturing capacity.



The hardness of rollers is lower than that of flat die, to ensure that they decrease the wear on flat die, and prolong their working life. important link should have the same clearance with the flat die to accomplish consistent stress. The clearance is between 0.1-0.3 mm.



The roller adopts conical form to guarantee the turning rate at the 2 ends coincide. This layout can stay clear of sliding of the roller, minimize energy waste, and reduce the wear of flat die. Besides, read here embraces an screw main stress modification device. It allows you to adjust the clearance between roller and die, so as to adapt to different products and make certain molding result.



How do the roller and flat die work?

When the raw products are fed into the pellet machine through the receptacle. 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. Throughout turning, the roller as well as flat die forms strong stress and fraction, which will certainly heat up the compression chamber to 80 ℃. In this condition, the materials come to be soften as well as very easy to mold and mildew.




The descending pressure from the roller press the raw materials into the holes on flat die, in which they are created right into cylindrical strips. The strips become much longer and much longer as the roller keep squeezing the raw materials. When the strips come out from all-time low of the holes, there is a slicer reducing them off. The cut strips fall down and discharge from the electrical outlet. These strips are what we call "wood pellets".



Apartment die and call die pellet mill comparison

Apartment die pellet machine appropriates for home use and also little workshop manufacturing. It sets you back low. The size is tiny and also the manufacturing is relatively low. For huge range production, ring die pellet machine has even more advantages. It has huge manufacturing capability as well as reduced power usage, however the size and expense is a lot larger. The significant difference in between ring die and flat die pellet machine are the shape of the dies and also the setting of rollers.



Ring die in pellet machine

Ring die is an annulus with numerous holes on it. It is constructed from carbon steel (alloy steel) and also stainless-steel, as well as refined by build and stamp, reducing, drilling as well as warmth treatment. The strength of the ring die is affected by the number of openings. i loved this of holes, the much less the number.



Rollers in ring die pellet machine

The rollers of ring die pellet machine are generally made of high-carbon steel or cooled actors iron. It should has higher hardness than the ring die, to ensure that it can recognize the very best compression impact as well as uniform abrasion. The ideal 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 materials.



How do the roller and ring die work?

In ring die pellet machine, the 2 rollers are installed inside the ring die. The roller placed stress outside on the inner wall surface of the ring die.



The raw products were first fed 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 also the ring die rotates drive by the electrical motor. As long as the raw products are gotten by the ring die, they are pressed into the holes. The high temperature as well as pressure create physical as well as chemical modifications to the raw materials. When they are extruded out from the ring die, there are slicers that cut them off. And the pellets falls down and also venture out through the outlet.
