Ball, Pebble and SAG Mills: A Buyers Guide

The Ball Mill. Much like all types of mills, the Ball Mill's purpose is to grind and blend material into smaller pieces. To do this, the material is fed into the cylinder at an angle and then rotated inside. During rotation, the material travels up the internal wall of the cylinder and then falls back down to the bottom of the structure.

Grindability - an overview | ScienceDirect Topics

As the HGI ball mill works on the same principle as pulverizing mills, the index obtained from this could give a fair assessment of the grinding capability of torrefied biomass. For biomass, one should use ( Agus and Water, 1971 ; Joshi, 1978) a standard volume of sample instead of mass to compare the grinding ease to coal and torrefied biomass.
