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 top quality. They are additionally the most wearable components. This short article presents the design of roller and also 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 parts for the pellet machine.



Apartment die in pellet machine.

In flat die pellet machine, the die is a disc with numerous openings on it. It is constructed from ductile actors iron. After carburizing and relieving grain pellet machine for sale , the solidity is 55-60HRC. The dimension of the holes are from 2.5 mm to 10mm. One of the most prominent sizes are 6mm, 8mm and also 10mm. To adapt to different materials as well as production need, the density as well as opening dimensions are various.



The working life of a flat die is 300-500 hrs. When one side has worn, it can be made use of with the other side. The length as well as dimension of the hole is made based on a lot of experiments, to ensure that it achieves the most effective compression proportion for 30 biomass products.



The flat die requirement to be changed when it breaks. It doesn't take much efforts. Simply loosen the lock nuts on both sides, remove the top framework and take out the roller and flat die. TICO supplies superior 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 installed on the major shaft. 2 or more rollers are connected by a roller shaft. The rollers are cyndrical tubes with numerous skid-proof ace on its surface area. During functioning, the roller shaft rotates around the primary shaft, and also the rollers revolve around the primary 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, so that they decrease the endure flat die, and lengthen their functioning life. All rollers should have the exact same clearance with the flat die to attain uniform pressure. pellet crumbler is between 0.1-0.3 mm.



The roller adopts conical shape to ensure the revolving speed at the 2 ends are the same. This layout can stay clear of slipping of the roller, lower energy waste, as well as reduce the wear of flat die. Besides, it embraces an screw main pressure change gadget. It allows you to readjust the clearance between roller and die, so as to adapt to different products as well as make sure molding impact.



Exactly how do the roller as well as flat die job?


When the raw materials are fed into the pellet machine via the hopper. They fall on the flat die and roller. The roller turns driven by the major shaft, as well as distribute the raw materials on the flat die evenly. Throughout revolving, the roller as well as flat die kinds strong pressure and also portion, which will certainly heat up the compression chamber to 80 ℃. In this condition, the products end up being soften and also very easy to mold.



The downward stress from the roller capture the raw materials right into the holes on flat die, in which they are developed into round strips. The strips end up being longer as well as much longer as the roller maintain squeezing the raw products. When the strips come out from the bottom of the holes, there is a slicer cutting them off. The cut strips drop and release from the electrical outlet. These strips are what we call "timber pellets".



Apartment die and ring die pellet mill comparison

Flat die pellet machine is suitable for residence use and tiny workshop manufacturing. It costs reduced. The dimension is tiny and also the production is fairly reduced. For large scale production, ring die pellet machine has even more benefits. It has big manufacturing ability and also reduced power intake, however the dimension and also cost is a lot larger. The major difference between ring die and flat die pellet machine are the form of the dies as well as the placement of rollers.



Ring die in pellet machine

Ring die is an annulus with lots of holes on it. It is made from carbon steel (alloy steel) and also stainless steel, as well as processed by forge as well as mark, cutting, drilling as well as warm treatment. The toughness of the ring die is influenced by the variety 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 constructed from high-carbon steel or chilled actors iron. It should has higher firmness than the ring die, so that it can recognize the very best compression result and consistent abrasion. The appropriate 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 products.



Exactly how do the roller and ring die work?

In ring die pellet machine, the 2 rollers are set up inside the ring die. The roller placed stress outward on the internal wall surface of the ring die.



The raw products were first fed into the conditioner for mixing. After that they are shared 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 ordered by the ring die, they are pressed into the holes. The high temperature and also stress cause physical and chemical changes to the raw products. When they are extruded out from the ring die, there are slicers that reduced them off. And the pellets falls down as well as get out through the outlet.
