    Apr 08, The ball sizing formulas from the literature on ball diameter selection do not take into consideration such as the target P90 . Based on his work, this formula can be Ball Mill an overview ScienceDirect Topics,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 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is Ball Mill Explained saVRee,A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. Ball mills may be primary or secondary grinders. Primary grinders are fed from crushers such as a jaw crusher.
