Pellet mill die and also roller design and also producer<br>
Roller and also die is the core part of the pellet machine They figures out the creating price and pellet top quality. They are likewise the most wearable parts. This short article presents the layout of roller as well as die in 2 types of pellet machine TICO is a specialist flat die pellet machine maker in China. We provide roller, flat die as well as other extra components for the pellet machine.




Apartment die in pellet machine.

In flat die pellet machine, the die is a disc with numerous holes on it. It is made from ductile actors iron. After carburizing as well as appeasing treatment, the hardness is 55-60HRC. The dimension of the holes are from 2.5 mm to 10mm. One of the most prominent sizes are 6mm, 8mm and also 10mm. To adapt to wood pellet machine and also manufacturing requirement, the density and also hole dimensions are different.



The functioning life of a flat die is 300-500 hrs. When one side has actually worn out, it can be utilized with the opposite. The size and dimension of the hole is developed based upon a multitude of experiments, to make sure that it achieves the very best compression ratio for 30 biomass products.



The flat die demand to be replaced when it breaks. It doesn't take much initiatives. Simply loosen the lock nuts on both sides, eliminate the top framework as well as obtain the roller and flat die. TICO gives remarkable extra components 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 major shaft. 2 or even more rollers are connected by a roller shaft. The rollers are cyndrical tubes with many skid-proof ace on its surface. Throughout functioning, the roller shaft revolves around the primary shaft, and the rollers revolve around the major shaft at the same time. The diameters of the rollers differ with the manufacturing capability.




The solidity of rollers is lower than that of flat die, so that they lower the endure flat die, and lengthen their working life. Richi machine should have the same clearance with the flat die to accomplish uniform pressure. The clearance is in between 0.1-0.3 mm.



The roller takes on conical shape to ensure the revolving rate at the 2 ends coincide. This layout can stay clear of sliding of the roller, lower power waste, as well as reduce the wear of flat die. Besides, it embraces an screw central pressure change gadget. It allows you to readjust the clearance in between roller as well as die, so regarding adapt to different products and guarantee molding result.



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

When the raw materials are fed right into the pellet machine with the hopper. They fall on the flat die and roller. The roller rotates driven by the major shaft, as well as disperse the raw materials on the flat die uniformly. During revolving, the roller and flat die kinds strong pressure and also fraction, which will warm up the compression chamber to 80 ℃. In this condition, the materials come to be soften and also very easy to mold and mildew.



The down stress from the roller press the raw products into the holes on flat die, in which they are developed into round strips. The strips come to be longer and much longer as the roller keep pressing the raw materials. When the strips appear from all-time low of the holes, there is a slicer cutting them off. The cut strips fall down as well as discharge from the electrical outlet. These strips are what we call "wood pellets".



Flat die as well as call die pellet mill contrast

Flat die pellet machine is suitable for residence use and also little workshop manufacturing. It costs reduced. The dimension is tiny and the production is reasonably low. For big range manufacturing, ring die pellet machine has more advantages. It has large manufacturing ability and also low power usage, however the dimension and cost is much larger. The significant distinction 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 several openings on it. It is made from carbon steel (alloy steel) and stainless steel, and also refined by create and also stamp, reducing, boring and heat therapy. The strength of the ring die is affected by the number of holes. The larger the dimension of holes, the much less the number.



Rollers in ring die pellet machine

The rollers of ring die pellet machine are usually made from high-carbon steel or cooled actors iron. It needs to has higher solidity than the ring die, so that it can realize the most effective compression impact as well as consistent abrasion. The ideal 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 hold of the raw products.



Just how do the roller and also ring die work?

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



The raw materials were first fed right into the conditioner for mixing. 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 grabbed by the ring die, they are squeezed into the holes. The heat as well as pressure trigger physical and also chemical changes to the raw products. When they are extruded out from the ring die, there are slicers that cut them off. And the pellets drops and also get out through the outlet.
