feed size ball mill

  • 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.

  • Feed Size VS Ball Size Grinding & Classification

    One can argue the f50 is a more realistic value since balls wear and the average ball size might be closer to half the maximum. Then the multiple would be closer to 13 times the maximum particle size fed to the ball mill. A f80 = 6 mm would need a ball size of 75 mm. An empirical model from "Emerging Trends in Mineral Processing", 2005, is often used:

  • Experimental Study on the Grinding Rate Constant of a

    ball diameter as a parameter. The feed size was the arithmetic mean of opening of sieves used to arrange the feed particles. K1 increases as feed size increases, and is independent of the ball diameter used. There is an optimum feed size at which K1 has a maximum. There is also a tendency for this optimum feed size to increase with ball diameter.

  • Ball Mills and Ball Charging Bulk Handling

    Grinding is the process of achieving particle size reduction through attrition and compressive forces at the granular level. The grinding media in a ball mill is typically steel or ceramic balls of varying sizes, depending on the feed size, work index of the ore and the size reduction and distribution required in the discharge.
