Pellet mill die and roller design and manufacturer<br>
Roller and die is the core part of the pellet machine They establishes the developing price and also pellet high quality. They are likewise the most wearable components. This short article introduces the style of roller as well as die in 2 types of pellet machine TICO is a specialist flat die pellet machine maker in China. We supply roller, flat die and also various other extra parts for the pellet machine.



Flat die in pellet machine.

In flat die pellet machine, the die is a disc with several holes on it. It is made of pliable actors iron. After carburizing as well as relieving treatment, the solidity is 55-60HRC. The size of the holes are from 2.5 mm to 10mm. One of the most preferred dimensions are 6mm, 8mm as well as 10mm. To adjust to different materials and also manufacturing need, the thickness and also opening sizes are different.




The functioning life of a flat die is 300-500 hours. When one side has worn out, it can be used with the other side. The length as well as size of the hole is developed based upon a great deal of experiments, to make sure that it achieves the very best compression proportion for 30 biomass products.



The flat die need to be replaced when it wears. It does not take much initiatives. Simply loosen up the lock nuts on both sides, get rid of the upper framework and take out the roller and flat die. commercial wood pellet machine offers remarkable extra components for the pellet machine, consisting of roller and also die.



Roller in flat die pellet machine.

In flat die pellet machine, the rollers are mounted on the primary shaft. 2 or more rollers are linked by a roller shaft. The rollers are cyndrical tubes with several skid-proof ace on its surface. During working, the roller shaft revolves around the primary shaft, as well as the rollers rotate around the main shaft at the same time. The sizes of the rollers differ with the production ability.



The solidity of rollers is less than that of flat die, to ensure that they decrease the endure flat die, as well as extend their functioning life. All rollers ought to have the exact same clearance with the flat die to achieve consistent stress. The clearance is between 0.1-0.3 mm.



The roller adopts conical shape to guarantee the revolving speed at the 2 ends are the same. This design can stay clear of sliding of the roller, decrease power waste, and also reduce the wear of flat die. Besides, it adopts an screw main stress modification gadget. It permits you to readjust the clearance in between roller and die, so as to adapt to various materials and make certain molding effect.



Exactly how do the roller and flat die job?

When the raw products are fed right into the pellet machine with the hopper. They fall on the flat die and also roller. The roller turns driven by the major shaft, as well as disperse the raw materials on the flat die evenly. During turning, the roller and flat die types strong stress and portion, which will heat up the compression chamber to 80 ℃. In this problem, the products become soften as well as easy to mold and mildew.



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



Flat die as well as call die pellet mill comparison

Apartment die pellet machine is suitable for home usage and also tiny workshop manufacturing. It sets you back reduced. The size is little as well as the manufacturing is reasonably reduced. For large scale production, ring die pellet machine has more benefits. It has huge manufacturing capacity as well as reduced power consumption, but the size and also price is a lot bigger. The significant difference between ring die and also flat die pellet machine are the shape of the dies and also the placement of rollers.



Ring die in pellet machine

Ring die is an annulus with several holes on it. It is made from carbon steel (alloy steel) as well as stainless-steel, as well as refined by build as well as mark, reducing, boring and heat treatment. The stamina of the ring die is affected by the variety of holes. The larger the size of openings, the much less the number.



Rollers in ring die pellet machine


The rollers of ring die pellet machine are normally constructed from high-carbon steel or cooled cast iron. It should has greater solidity than the ring die, so that it can realize the most effective compression result as well as consistent abrasion. The ideal clearance between the rollers and also ring die is 0.1-0.4 mm. There are axial grooves on the surface area of the roller to grab the raw materials.



How do the roller and ring die work?

In ring die pellet machine, the 2 rollers are set up inside the ring die. Richi machine put pressure outside on the internal wall surface of the ring die.



The raw products were first fed right into the conditioner for mixing. After that they are shared to the compression chamber by a screw feeder. In paper pellet mill , the rollers are still and also the ring die rotates drive by the electric motor. As long as the raw products are ordered by the ring die, they are pressed right into the holes. The high temperature as well as pressure cause physical and chemical adjustments 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 and also go out with the electrical outlet.
