Pellet mill die and roller layout as well as manufacturer<br>
richi pellet and also die is the core part of the pellet machine They determines the forming rate as well as pellet high quality. They are also the most wearable parts. This post presents the layout of roller and die in 2 sorts of pellet machine TICO is an expert flat die pellet machine supplier in China. We supply roller, flat die and other spare parts for the pellet machine.



Apartment die in pellet machine.

In flat die pellet machine, the die is a disc with many openings on it. It is made of ductile actors iron. After carburizing and relieving treatment, the solidity is 55-60HRC. The dimension of the holes are from 2.5 mm to 10mm. Richi machinery are 6mm, 8mm and 10mm. To adjust to different materials and production requirement, the thickness as well as hole dimensions are different.



The working life of a flat die is 300-500 hrs. When one side has actually worn out, it can be utilized with the opposite. The length and also dimension of the hole is made based upon a multitude of experiments, so that it attains the very best compression proportion for 30 biomass materials.



The flat die demand to be replaced when it wears out. It doesn't take much initiatives. Just loosen up the lock nuts on both sides, eliminate the top framework and also secure the roller as well as flat die. TICO supplies exceptional 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 main shaft. 2 or more rollers are attached by a roller shaft. The rollers are cylinders with numerous skid-proof ace on its surface. Throughout functioning, the roller shaft revolves around the main shaft, and the rollers turn around the major shaft at the same time. The diameters of the rollers vary with the production capability.



The solidity of rollers is less than that of flat die, so that they minimize the endure flat die, as well as lengthen their functioning life. All rollers should have the exact same clearance with the flat die to attain consistent stress. The clearance is between 0.1-0.3 mm.



The roller takes on conical shape to make certain the revolving rate at the 2 ends are the same. This style can stay clear of sliding of the roller, minimize energy waste, and also reduce the wear of flat die. Besides, it adopts an screw central pressure modification device. It enables you to readjust the clearance between roller as well as die, so regarding adapt to various materials and ensure molding impact.



How do the roller and also flat die job?

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 primary shaft, as well as distribute the raw products on the flat die evenly. Throughout revolving, the roller and also flat die types solid pressure as well as fraction, which will certainly warm up the compression chamber to 80 ℃. In this problem, the products become soften and also simple to mold and mildew.



The down pressure from the roller press the raw products right into the holes on flat die, in which they are created right into cylindrical strips. The strips end up being longer and longer as the roller keep squeezing the raw products. When the strips appear from the bottom of the holes, there is a slicer cutting them off. The cut strips fall down as well as release from the electrical outlet. These strips are what we call "timber pellets".





Flat die and ring die pellet mill contrast

Flat die pellet machine appropriates for residence use and small workshop manufacturing. It costs reduced. The dimension is small and the production is fairly reduced. For big range production, ring die pellet machine has even more advantages. It has huge production ability and also reduced power intake, yet the dimension as well as expense is a lot larger. The major distinction between ring die and also flat die pellet machine are the shape of the dies and also the placement 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) as well as stainless steel, and processed by forge and stamp, cutting, exploration as well as warm therapy. The stamina of the ring die is influenced by the variety of openings. The bigger the dimension of openings, the much less the number.



Rollers in ring die pellet machine

The rollers of ring die pellet machine are typically constructed from high-carbon steel or cooled actors iron. It ought to has greater solidity than the ring die, so that it can realize the most effective compression effect as well as consistent abrasion. The appropriate clearance between the rollers and ring die is 0.1-0.4 mm. There are axial grooves on the surface of the roller to get hold of the raw materials.



How do the roller and ring die job?

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



The raw materials were first fed into the conditioner for mixing. Then 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 ordered by the ring die, they are pressed right into the holes. The heat and pressure trigger physical and chemical changes to the raw materials. When they are extruded out from the ring die, there are slicers that reduced them off. And also the pellets drops and go out with the outlet.
