The advantage of the grid type ball mill is that the ore discharge speed is fast, it can reduce the over-crushing of ore, and at the same time it can increase the output per unit volume. 1. Large row of ore mouth design, stronger processing capacity for lithium ore, up to 160t/h; 2. Equipped with an automatic control system PLC, reducing labor costs, …
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.
