hydrocyclone in ball mill
Hydrocyclones - an overview | ScienceDirect Topics
The ball mill accepts the oversize from hydrocyclone sizing of the SAG mill product. 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 ...
