Ball mill reduwes the size upto

5. Ball mill The ball mill consists of hollow cylindrical rotating shell made of steel lined with porcelain or high carbon steel plate. Upto 50 % of its volume, the shell is filled with balls made of steel or pebbles. The balls are of constant weight and varying size which depend on the amount of feed. The size reduction happens due to the

    A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. T

    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
