    Roll Mill an overview ScienceDirect Topics

    4.2.3.1.1 Roll Mills. The roll mill is the simplest batch mixing equipment. The principal design consists of two horizontal rolls, usually of equal size, arranged side by side and rotating toward each other at different speeds. The ratio of the peripheral speeds of the rolls, known as friction ratio, ranges from 1 to 2 but is usually around 1.2. The higher friction ratio leads to a higher heat

    Ball Mill an overview ScienceDirect Topics

    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. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones. The
