Pellet mill die and roller design and also manufacturer<br>
Roller and also die is the core part of the pellet machine They determines the forming price as well as pellet top quality. fish feed pelleting machine price are additionally one of the most wearable components. This article presents the layout of roller as well as die in 2 kinds of pellet machine TICO is a specialist flat die pellet machine maker in China. We provide roller, flat die and 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 openings on it. It is constructed from ductile cast iron. After carburizing and quenching therapy, the firmness is 55-60HRC. The dimension of the holes are from 2.5 mm to 10mm. The most popular sizes are 6mm, 8mm and also 10mm. To adapt to different materials as well as manufacturing need, the thickness as well as hole sizes are different.



The functioning life of a flat die is 300-500 hours. When one side has worn out, it can be made use of with the other side. The length as well as size of the hole is made based upon a large number of experiments, to make sure that it attains the most effective 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 the lock nuts on both sides, remove the upper chassis and take out the roller and flat die. TICO provides superior extra components for the pellet machine, including roller and also die.




Roller in flat die pellet machine.

In flat die pellet machine, the rollers are set up on the primary shaft. 2 or even more rollers are attached by a roller shaft. The rollers are cyndrical tubes with many skid-proof ace on its surface. During functioning, the roller shaft turns around the main shaft, and the rollers rotate around the main shaft at the same time. The diameters of the rollers differ with the manufacturing capacity.



The solidity of rollers is lower than that of flat die, to make sure that they decrease the endure flat die, and lengthen their functioning life. All rollers should have the same clearance with the flat die to attain consistent pressure. The clearance is in between 0.1-0.3 mm.



The roller adopts tapered form to guarantee the turning speed at the 2 ends are the same. This design can prevent slipping of the roller, reduce energy waste, and also reduce the wear of flat die. Besides, it embraces an screw central pressure adjustment gadget. It allows you to adjust the clearance in between roller and die, so as to adapt to different materials and guarantee molding effect.



Just 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, and distribute the raw products on the flat die evenly. Throughout turning, the roller and also flat die types solid pressure as well as portion, which will certainly warm up the compression chamber to 80 ℃. In this problem, the products end up being soften and also easy to mold and mildew.



The downward pressure from the roller squeeze the raw materials into the holes on flat die, in which they are developed right into round strips. The strips come to be much longer as well as much longer as the roller maintain pressing the raw products. 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 outlet. These strips are what we call "wood pellets".



Apartment die and ring die pellet mill comparison

Flat die pellet machine appropriates for residence use and also small workshop manufacturing. It sets you back reduced. The size is small as well as the production is reasonably reduced. For large range production, ring die pellet machine has more benefits. It has big production capacity and low power intake, but the dimension and also price is much bigger. The major distinction between ring die and also flat die pellet machine are the shape of the dies and the setting of rollers.



Ring die in pellet machine

Ring die is an annulus with several holes on it. It is made of carbon steel (alloy steel) and stainless-steel, and also processed by build and mark, reducing, boring and warmth treatment. The toughness of the ring die is affected by the number of openings. The larger the dimension of holes, the less the number.



Rollers in ring die pellet machine

The rollers of ring die pellet machine are generally made of high-carbon steel or chilled cast iron. It must has greater solidity than the ring die, so that it can recognize the best compression effect as well as uniform abrasion. richi pellet mill between the rollers and also ring die is 0.1-0.4 mm. There are axial grooves on the surface of the roller to order the raw materials.



How do the roller as well as ring die job?

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




The raw products were first fed into the conditioner for mixing. Then they are conveyed 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 materials are gotten hold of by the ring die, they are squeezed right into the holes. The heat and stress cause 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 drops and venture out through the electrical outlet.
