Pellet mill die as well as roller design as well as maker<br>
Roller and die is the core part of the pellet machine They determines the creating rate and also pellet quality. They are additionally the most wearable parts. This write-up introduces the style of roller and die in 2 types of pellet machine TICO is a professional flat die pellet machine manufacturer in China. We provide roller, flat die and other extra parts for the pellet machine.



Flat die in pellet machine.


In flat die pellet machine, the die is a disc with many openings on it. It is constructed from ductile cast iron. After carburizing and also satiating therapy, the firmness is 55-60HRC. The size of the holes are from 2.5 mm to 10mm. One of the most prominent dimensions are 6mm, 8mm and 10mm. To adapt to different products and manufacturing demand, the density and opening sizes are various.



The functioning life of a flat die is 300-500 hrs. When one side has worn out, it can be used with the other side. The length and size of the hole is made based upon a multitude of experiments, to make sure that it achieves the most effective compression proportion for 30 biomass products.



The flat die requirement to be changed when it wears. It does not take much initiatives. Just loosen the lock nuts on both sides, remove the top framework and also secure the roller and flat die. TICO offers exceptional spare components for the pellet machine, consisting of roller as well as die.




Roller in flat die pellet machine.

In flat die pellet machine, the rollers are installed on the main 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 area. During functioning, the roller shaft rotates around the major shaft, and the rollers turn around the major shaft at the same time. The diameters of the rollers differ with the manufacturing capability.



The hardness of rollers is less than that of flat die, so that they lower the endure flat die, and also extend their working life. All rollers must have the same clearance with the flat die to achieve uniform stress. The clearance is between 0.1-0.3 mm.



The roller embraces tapered shape to make sure the revolving speed at the 2 ends coincide. This design can prevent sliding of the roller, minimize power waste, as well as minimize the wear of flat die. Besides, it adopts an screw central stress modification tool. It permits you to adjust the clearance in between roller as well as die, so as to adapt to various products and ensure molding impact.



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

When the raw products are fed right into the pellet machine via the hopper. They fall on the flat die and also roller. The roller turns driven by the primary shaft, and also distribute the raw materials on the flat die uniformly. During rotating, the roller as well as flat die forms solid pressure and also portion, which will warm up the compression chamber to 80 ℃. In this condition, the materials come to be soften and easy to mold.



The descending pressure from the roller squeeze the raw products into the holes on flat die, in which they are formed into cylindrical strips. The strips come to be longer and also longer as the roller keep squeezing the raw products. When the strips 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".



Flat die and also sound die pellet mill comparison

Apartment die pellet machine appropriates for residence use as well as little workshop production. It sets you back reduced. The size is tiny and the production is fairly low. For big range production, ring die pellet machine has even more advantages. It has huge production capacity and also low power usage, yet the size and cost is a lot bigger. The significant distinction in between ring die and flat die pellet machine are the form of the dies and also the position 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) as well as stainless-steel, and also processed by create as well as mark, cutting, drilling and warmth treatment. The strength of the ring die is influenced by the number of holes. The larger the dimension of holes, the less the number.



Rollers in ring die pellet machine

The rollers of ring die pellet machine are normally made from high-carbon steel or cooled cast iron. It must has greater hardness than the ring die, to make sure that it can realize the best compression impact and consistent abrasion. The ideal clearance in between the rollers as well as 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 placed pressure outward on the inner wall of the ring die.



The raw products were first fed right into the conditioner for mixing. After that rabbit feed pellet making machine 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 products are gotten hold of by the ring die, they are squeezed into the holes. The heat and stress cause physical and also chemical adjustments to the raw products. When they are extruded out from the ring die, there are slicers that reduced them off. As well as diy pelletizer falls down and venture out through the outlet.
