Pellet mill die and also roller design and also producer<br>
Roller and die is the core part of the pellet machine They determines the forming price as well as pellet top quality. They are likewise the most wearable components. This article introduces the design of roller as well as die in 2 kinds of pellet machine TICO is a specialist flat die pellet machine manufacturer in China. We provide roller, flat die as well as other spare parts for the pellet machine.



Flat die in pellet machine.

In flat die pellet machine, the die is a disc with several openings on it. It is made of ductile actors iron. After carburizing and quenching treatment, the solidity is 55-60HRC. The dimension of the holes are from 2.5 mm to 10mm. One of the most preferred dimensions are 6mm, 8mm and 10mm. To adjust to extruder and pelletizer and also manufacturing demand, the density as well as hole dimensions are various.



The working life of a flat die is 300-500 hrs. When one side has actually broken, it can be used with the opposite. The length and also dimension of the hole is created based upon a multitude of experiments, to make sure that it attains the most effective compression proportion for 30 biomass products.



The flat die demand to be replaced when it wears out. It doesn't take much efforts. Simply loosen the lock nuts on both sides, remove the upper framework and also obtain the roller and also flat die. TICO offers exceptional extra parts for the pellet machine, including roller and die.



Roller in flat die pellet machine.

In flat die pellet machine, the rollers are mounted on the major shaft. 2 or even more rollers are attached by a roller shaft. The rollers are cylinders with numerous skid-proof ace on its surface area. Throughout working, the roller shaft turns around the main shaft, as well as the rollers revolve around the primary shaft at the same time. The sizes of the rollers vary with the production ability.



The solidity of rollers is lower than that of flat die, to make sure that they decrease the wear on flat die, and also lengthen their working life. All rollers should have the same clearance with the flat die to achieve consistent stress. The clearance is between 0.1-0.3 mm.



The roller takes on tapered form to ensure the rotating speed at the 2 ends are the same. This layout can avoid slipping of the roller, lower energy waste, and also decrease the wear of flat die. Besides, it adopts an screw central pressure change tool. It enables you to readjust the clearance in between roller and also die, so as to adapt to various products and make certain molding impact.



How do the roller and flat die work?


When the raw products are fed right into the pellet machine through the hopper. They fall on the flat die as well as roller. The roller rotates driven by the primary shaft, and distribute the raw products on the flat die evenly. During rotating, the roller and also flat die types strong stress and fraction, which will heat up the compression chamber to 80 ℃. In this problem, the materials end up being soften and simple to mold and mildew.



The descending pressure from the roller capture the raw materials right into the holes on flat die, in which they are developed right into round strips. The strips come to be much longer and longer as the roller maintain squeezing the raw materials. When pellet mill equipment come out from all-time low 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".




Apartment die and also call die pellet mill comparison

Apartment die pellet machine appropriates for residence use as well as small workshop manufacturing. It costs reduced. The size is small and the production is fairly reduced. For huge scale production, ring die pellet machine has more benefits. It has big production capacity as well as low power intake, but the dimension and price is much larger. The major difference between ring die as well as flat die pellet machine are the form of the dies and the setting of rollers.



Ring die in pellet machine

Ring die is an annulus with numerous openings on it. It is made of carbon steel (alloy steel) and also stainless steel, as well as processed by forge as well as mark, reducing, exploration as well as warm treatment. The strength 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 usually constructed from high-carbon steel or cooled actors iron. It ought to has higher firmness than the ring die, to ensure that it can recognize the very best compression effect and also consistent abrasion. The ideal clearance in 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 materials.



Exactly how do the roller and ring die job?

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



The raw materials were first fed into the conditioner for blending. After that https://extruschuler.com/floating-fish-feed-making-machine-plant/ are communicated 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 high temperature and pressure cause 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 the pellets falls down as well as get out through the outlet.
