Pellet mill die and roller layout and maker<br>
Roller and also die is the core part of the pellet machine They figures out the forming rate and pellet high quality. They are additionally the most wearable parts. This write-up introduces the layout of roller and die in 2 kinds of pellet machine TICO is a specialist flat die pellet machine maker in China. We provide 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 numerous holes on it. straw pellet mill for sale is made of ductile cast iron. After carburizing and also satiating therapy, the hardness is 55-60HRC. The size of the holes are from 2.5 mm to 10mm. One of the most prominent sizes are 6mm, 8mm as well as 10mm. To adjust to different products and also production need, the thickness and opening dimensions are different.



The working life of a flat die is 300-500 hours. When one side has actually worn out, it can be utilized with the other side. The length and also dimension of the hole is designed based upon a great deal of experiments, to ensure that it achieves the best compression proportion for 30 biomass products.



The flat die demand to be replaced when it wears. It does not take much efforts. Just loosen the lock nuts on both sides, eliminate the top framework and also obtain the roller as well as flat die. TICO provides premium 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 installed on the major shaft. 2 or even more rollers are linked by a roller shaft. The rollers are cyndrical tubes with several skid-proof ace on its surface. During functioning, the roller shaft turns around the primary shaft, and the rollers revolve around the main shaft at the same time. The sizes of the rollers differ with the manufacturing capacity.



The firmness of rollers is lower than that of flat die, to make sure that they reduce the wear on flat die, as well as lengthen their functioning life. All rollers need to have the same clearance with the flat die to accomplish consistent pressure. The clearance is in between 0.1-0.3 mm.



The roller takes on conical form to guarantee the rotating rate at the 2 ends are the same. This style can prevent sliding of the roller, decrease energy waste, as well as decrease the wear of flat die. Besides, it adopts an screw main stress adjustment device. It allows you to readjust the clearance in between roller and also die, so regarding adapt to different materials and also make certain molding impact.



How do the roller as well as flat die job?

When the raw products are fed right into the pellet machine through the receptacle. They fall on the flat die and also roller. The roller turns driven by the main shaft, as well as distribute the raw materials on the flat die uniformly. Throughout turning, the roller as well as flat die kinds strong stress and fraction, which will certainly heat up the compression chamber to 80 ℃. In richi pellet mill , the materials become soften as well as very easy to mold.



The downward pressure from the roller press the raw materials right into the holes on flat die, in which they are formed right into round strips. The strips end up being longer as well as 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 drop and discharge from the electrical outlet. These strips are what we call "wood pellets".



Apartment die and also sound die pellet mill contrast

Apartment die pellet machine appropriates for residence usage and also tiny workshop manufacturing. It costs reduced. The dimension is tiny as well as the manufacturing is fairly low. For huge range production, ring die pellet machine has even more advantages. It has big production ability and also low power usage, but the size and also price is much larger. The significant difference in between ring die and flat die pellet machine are the form of the dies and also the position of rollers.



Ring die in pellet machine

Ring die is an annulus with several openings on it. It is made from carbon steel (alloy steel) and stainless steel, and also processed by create and stamp, cutting, boring and warmth therapy. The toughness of the ring die is influenced by the variety of openings. The bigger the size of holes, the less the number.



Rollers in ring die pellet machine

The rollers of ring die pellet machine are normally made from high-carbon steel or cooled cast iron. It should has higher firmness than the ring die, so that it can realize the best compression result as well as uniform abrasion. The ideal clearance in between the rollers as well as ring die is 0.1-0.4 mm. There are axial grooves on the surface area of the roller to order the raw materials.



Exactly how do the roller as well as ring die work?

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



The raw materials were first fed into the conditioner for blending. After that they are communicated 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 products are gotten by the ring die, they are pressed right into the holes. The heat and pressure trigger physical and chemical modifications to the raw materials. When they are extruded out from the ring die, there are slicers that cut them off. And also the pellets falls down and also venture out through the electrical outlet.
