Pellet mill die and roller style as well as supplier<br>
Roller as well as die is the core part of the pellet machine They establishes the developing rate and pellet quality. They are also one of the most wearable components. This article presents the design of roller as well as die in 2 sorts of pellet machine TICO is a professional flat die pellet machine maker in China. We supply roller, flat die and various other extra components 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 of pliable actors iron. After carburizing as well as satiating treatment, the hardness is 55-60HRC. The size of the holes are from 2.5 mm to 10mm. The most preferred sizes are 6mm, 8mm and also 10mm. To adapt to various materials and production demand, the thickness as well as hole sizes are different.



The working life of a flat die is 300-500 hours. When one side has worn out, it can be utilized with the opposite side. The length and also size of the hole is developed based upon a great deal of experiments, to make sure that it attains the very best compression ratio for 30 biomass products.



The flat die requirement to be changed when it wears. It doesn't take much efforts. Simply loosen the lock nuts on both sides, get rid of the upper framework and also take out the roller as well as flat die. TICO provides 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 cylinders with numerous skid-proof ace on its surface area. During functioning, the roller shaft turns around the main shaft, as well as the rollers turn around the main shaft at the same time. The sizes of the rollers vary with the manufacturing capacity.




The firmness of rollers is lower than that of flat die, to ensure that they decrease the endure flat die, and also prolong their functioning life. All rollers should have the exact same clearance with the flat die to achieve consistent pressure. The clearance is between 0.1-0.3 mm.



The roller embraces conical shape to make sure the turning speed at the 2 ends coincide. This style can prevent sliding of the roller, decrease energy waste, and minimize the wear of flat die. Besides, richi machinery adopts an screw central stress adjustment gadget. It allows you to readjust the clearance in between roller as well as die, so regarding adjust to various products as well as make certain molding result.



How do the roller and also flat die job?

When the raw products are fed right into the pellet machine through the receptacle. They fall on the flat die and roller. The roller rotates driven by the primary shaft, and also distribute the raw products on the flat die evenly. During revolving, the roller and flat die kinds solid stress as well as fraction, which will certainly heat up the compression chamber to 80 ℃. In this condition, the products come to be soften as well as easy to mold.



The down stress from the roller capture the raw products right into the holes on flat die, in which they are formed right into round strips. The strips become longer and also much longer as the roller maintain squeezing the raw products. When the strips appear from the bottom of the holes, there is a slicer cutting them off. The cut strips drop and also discharge from the outlet. These strips are what we call "wood pellets".



Flat die and call die pellet mill comparison

Apartment die pellet machine is suitable for home usage and also small workshop manufacturing. It sets you back low. The dimension is little as well as the production is relatively low. For large scale production, ring die pellet machine has even more advantages. It has large manufacturing capability as well as low power consumption, yet the dimension and price is much larger. The significant difference in between ring die and also flat die pellet machine are the form of the dies and also the placement 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, as well as processed by create and also stamp, reducing, drilling and warm 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 generally made of high-carbon steel or chilled cast iron. It needs to has greater hardness than the ring die, so that it can understand the very best compression result and consistent abrasion. The suitable clearance in between the rollers and 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 and ring die job?

In ring die pellet machine, the 2 rollers are mounted inside the ring die. The roller put stress outside on the internal wall of the ring die.



The raw products were first fed into the conditioner for blending. After that 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 electric motor. As long as the raw products are grabbed by the ring die, they are pressed into the holes. The high temperature and also pressure cause physical and also chemical changes to the raw materials. When animal feed pellet machine price are extruded out from the ring die, there are slicers that reduced them off. And the pellets falls down as well as go out through the outlet.
