Pellet press die for bio-mass Pellet
1. Alloy dies
This is the choice for many feed processors because of their good abrasion and breakage resistance.
2. Carbon steel die
They have superior corrosion resistance, making them the choice for processing operations involving corrosive chemicals.
3. Stainless steel dies
They have the best abrasion and breakage resistance as well as good corrosion resistance.
Relation between die hole structure and pelleting
1,Straight hole and release stepped hole
It is suitable for compound feed processing
2,External conical hole
It is suitable for the processing of high-fibre feed like de-fat chaff
3,Internal conical hole and compression-type stepped hole
This applicable for the process of herbage powder feed of light proportion
We should try to avoid using release stepped hole(pressure-relief vent)
Because discharing is not easy for holes in the rows of the edge of ring die, pressure-relief vent is designed there.
