Pellet mill die and roller design and manufacturer
Pellet mill die and also roller design and manufacturer
Roller and also die is the core part of the pellet machine They determines the developing rate and also pellet top quality. They are additionally one of the most wearable components. This article presents the design of roller and die in 2 types of pellet machine TICO is a professional flat die pellet machine manufacturer in China. We supply roller, flat die as well as various other extra parts for the pellet machine.

Flat die in pellet machine.

In flat die pellet machine, the die is a disc with lots of holes on it. It is made from pliable 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. The most preferred dimensions are 6mm, 8mm and 10mm. To adapt to various materials as well as production demand, the thickness and also hole sizes are various.

The functioning life of a flat die is 300-500 hrs. When one side has actually worn out, it can be used with the opposite. The size and also size of the hole is made based upon a lot of experiments, so that it attains the very best compression ratio for 30 biomass materials.

The flat die need to be changed when it breaks. It does not take much initiatives. Just loosen the lock nuts on both sides, remove the upper chassis 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 victor pellet machine , the rollers are installed on the main shaft. 2 or more rollers are attached by a roller shaft. The rollers are cylinders with several skid-proof ace on its surface area. During working, the roller shaft turns around the major shaft, as well as the rollers turn around the main shaft at the same time. The diameters of the rollers differ with the manufacturing ability.

The firmness of rollers is lower than that of flat die, to make sure that they lower the endure flat die, and lengthen their working life. All rollers need to have the same clearance with the flat die to achieve consistent stress. The clearance is between 0.1-0.3 mm.

The roller embraces conical form to guarantee the revolving rate at the 2 ends are the same. This layout can prevent slipping of the roller, lower energy waste, and reduce the wear of flat die. Besides, it adopts an screw central pressure adjustment tool. It permits you to change the clearance in between roller and also die, so as to adapt to different materials as well as make certain molding result.

How do the roller as well as flat die work?
When the raw materials are fed into the pellet machine with the hopper. They fall on the flat die and roller. The roller rotates driven by the primary shaft, and distribute the raw materials on the flat die uniformly. During revolving, the roller as well as flat die types strong pressure and fraction, which will heat up the compression chamber to 80 ℃. In this problem, the materials come to be soften and simple to mold.

The descending stress from the roller squeeze the raw materials right into the holes on flat die, in which they are formed into cylindrical strips. The strips become longer and much longer as the roller keep squeezing the raw materials. When the strips come out from the bottom of the holes, there is a slicer cutting them off. The cut strips drop and also release from the outlet. These strips are what we call "wood pellets".

Flat die and also sound die pellet mill comparison
Apartment die pellet machine is suitable for residence use and also tiny workshop manufacturing. It costs low. homemade pellet maker is tiny as well as the manufacturing is relatively reduced. For large range manufacturing, ring die pellet machine has more advantages. It has big manufacturing ability and low power consumption, yet the dimension as well as cost is a lot bigger. The significant distinction in 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. biomass wood pellet machine is made of carbon steel (alloy steel) as well as stainless steel, and processed by create and stamp, reducing, exploration and warmth treatment. The toughness of the ring die is affected by the variety of holes. The larger the dimension of openings, the less the number.


Rollers in ring die pellet machine
The rollers of ring die pellet machine are usually made of high-carbon steel or cooled actors iron. It ought to has higher solidity than the ring die, to make sure that it can recognize the very best compression effect as well as consistent abrasion. The ideal clearance between the rollers and ring die is 0.1-0.4 mm. There are axial grooves on the surface area of the roller to get the raw products.

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 pressure outside on the inner wall of the ring die.

The raw materials were first fed right 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 as well as the ring die rotates drive by the electric motor. As long as the raw products are ordered by the ring die, they are squeezed right into the holes. The high temperature and stress 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 also the pellets falls down and venture out via the electrical outlet.
