Pellet mill die and roller design and also maker<br>
Roller and also die is the core part of the pellet machine They establishes the creating price as well as pellet high quality. They are also one of the most wearable components. This post presents the layout of roller as well as die in 2 sorts of pellet machine TICO is an expert flat die pellet machine producer in China. We supply roller, flat die as well as various other extra components for the pellet machine.





Apartment die in pellet machine.

In flat die pellet machine, the die is a disc with several openings on it. It is made from pliable cast iron. After carburizing and appeasing treatment, the solidity is 55-60HRC. The size of the holes are from 2.5 mm to 10mm. The most preferred sizes are 6mm, 8mm as well as 10mm. To adapt to different products and production requirement, the thickness and opening sizes are various.



The working life of a flat die is 300-500 hours. When one side has actually worn, it can be utilized with the opposite. The size as well as size of the hole is designed based on a large number of experiments, to make sure that it accomplishes the very best compression ratio for 30 biomass materials.



The flat die need to be changed when it wears. It does not take much initiatives. Just loosen Richi machinery on both sides, eliminate the top chassis as well as obtain the roller as well as flat die. TICO gives premium extra parts for the pellet machine, including roller as well as die.



Roller in flat die pellet machine.

In flat die pellet machine, the rollers are mounted on the main shaft. 2 or more rollers are connected by a roller shaft. The rollers are cylinders with numerous skid-proof ace on its surface. During functioning, the roller shaft revolves around the main shaft, and the rollers turn around the major shaft at the same time. The diameters of the rollers vary with the production capability.



The hardness of rollers is lower than that of flat die, to ensure that they lower the wear on flat die, and extend their functioning life. All rollers need to have the exact same clearance with the flat die to achieve consistent stress. The clearance is in between 0.1-0.3 mm.



The roller embraces tapered form to ensure the revolving speed at the 2 ends are the same. This design can stay clear of sliding of the roller, reduce power waste, and decrease the wear of flat die. Besides, it takes on an screw main pressure modification device. It permits you to readjust the clearance in between roller as well as die, so regarding adjust to different materials as well as make sure molding result.



How do the roller and flat die work?

When the raw materials are fed right into the pellet machine via the hopper. They fall on the flat die and also roller. The roller revolves driven by the primary shaft, and disperse the raw materials on the flat die equally. Throughout rotating, the roller and flat die kinds strong pressure and also fraction, which will certainly heat up the compression chamber to 80 ℃. In this condition, the products end up being soften as well as very easy to mold and mildew.



The down stress from the roller squeeze the raw products right into the holes on flat die, in which they are developed into round strips. The strips become much longer and also longer as the roller keep pressing the raw products. When the strips come out from the bottom of the holes, there is a slicer reducing them off. The cut strips fall down and also discharge from the outlet. These strips are what we call "wood pellets".



Apartment die as well as ring die pellet mill contrast

Apartment die pellet machine is suitable for home use and small workshop manufacturing. It costs reduced. The size is little and the production is fairly reduced. For big scale production, ring die pellet machine has more benefits. It has big manufacturing capacity and low power intake, yet the dimension and expense is much larger. The major difference between ring die as well as flat die pellet machine are the shape of the dies and also the position of rollers.



Ring die in pellet machine

Ring die is an annulus with numerous holes on it. It is made of carbon steel (alloy steel) and also stainless steel, and also refined by create and also stamp, cutting, drilling as well as heat therapy. The toughness of the ring die is influenced by the variety of openings. 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 constructed from high-carbon steel or chilled cast iron. It should has higher firmness than the ring die, to make sure that it can recognize the best compression effect and uniform abrasion. more information between the rollers and also ring die is 0.1-0.4 mm. There are axial grooves on the surface of the roller to get the raw materials.



Just how do the roller and also ring die job?

In ring die pellet machine, the 2 rollers are installed inside the ring die. The roller put stress exterior on the inner wall of the ring die.



The raw products were first fed right into the conditioner for blending. After that they are communicated 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 materials are grabbed by the ring die, they are pressed into the holes. The heat and also pressure trigger physical as well as chemical modifications to the raw products. When they are extruded out from the ring die, there are slicers that cut them off. And also the pellets drops and get out via the outlet.
