EFFECT OF BALL SIZE DISTRIBUTION ON MILLING

EFFECT OF BALL SIZE DISTRIBUTION ON MILLING

Pulverizing is typically defined as 25 mesh and beyond Mesh vs Microns Mesh size refers to the number of openings in one inch of screen For example a 4mesh screen means that there are four squares within one inch of the screen As the mesh size increases the particle size decreases to create a finer material Mesh size is not a precise Ball mills give a controlled final grind and produce flotation feed of a uniform size Ball mills tumble iron or steel balls with the ore The balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds The feed to ball mills dry basis is typically 75 vol ore and 25 steel
