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.

2019-9-1  Having acknowledged that little is still known about the effects of the feed size distributions on the production of a given target size class, this work thus intends to shed light on this grey area in the research by combining PBM and AR to investigate how ball milling can be optimised from a feed size distribution perspective to produce the maximum amount of the desired size class (−150 + 25 μm), for

Ball Mill Parameter Selection & Calculation Power

2019-8-30  In the ball mill, the size and proportion of steel balls have a great influence on the productivity and working efficiency of the mill. For coarse and hard materials, larger steel balls should be selected, for fine and brittle materials, with smaller diameter steel balls, the impact times of steel balls in the mill increase with the decrease of ball diameter, and the grinding between balls increases.
