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 typically 75 vol.-% ore and 25% steel.AMIT 135: Lesson 7 Ball Mills & Circuits – Mining Mill,,Ball Mill Design Parameters. Size rated as diameter x length.
