When the first solenoid popped open, the bottom ball would be allowed through while the second solenoid held the remaining column of balls.

SIZE REDUCTION AND SIZE SEPARATION

Hardinge mill: In this type of ball mills the cylinder has a conical end towards a discharge point. In this mill the larger balls remain within the cylinder and the smaller balls are collected in the conical portion. As a result, coarser grinding takes place in the cylinder portion and finer grinding takes place in the apex of the conical portion.

The Evolution of Grinding Mill Power Models

Jan 30, 2019In this method, the contents of the mill charge, instead of being modeled as a single mass, is given individual identity to each and every ball. The grinding balls are modeled as spheres and the mill shell is modeled as a long cylinder and the exact geometry of the lifter bars is modeled with exact planar dimensions.
