    Addition of pebbles to a ball-mill to improve grinding

    The theory of pebble wear was developed during this investigation, for application to batch grinding tests. The size distribution of the pebbles was measured after each test and the theory was used to calculate the pebble wear rate (mm h-1) and the specific wear rate (kg h-1 kg-1) for all screen fractions. The wear rate of pebbles in the presence of balls was higher than that for pebbles alone

    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
