WhatsApp: +86 18838072829Ball mills tumble iron or steel balls. The balls are initially 5 to 10 cm diameter. They gradually wear away as grinding proceeds. Ball mills typically contain about 75% ore and 25% 'steel' (by volume). They give a controlled final grind. The ball mill accepts the semiautogenous or autogenous mill product. It produces uniformsize flotation feed.
