Ball mill dry or slurry condition

Ball mill dry or slurry condition

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

    Wet Ball Mill = kg kWh = 0.16(A i-0.015) 0.33; Dry Ball Mill = kg / kWh = 0.023A i 0.5; Replacement Ball Size. Rowland and Kjos proposed the use of their equation for the determination of the initial and replacement media size. Azzaroni (1981) and Dunn (1989) recommended the use of the following expression for the size of the makeup media:

  • Wet Ball Milling Vs Dry Ball Milling | Orbis Machinery, LLC Wet Ball Milling Vs Dry Ball Milling | Orbis Machinery, LLC

    Jun 27, 2019 In the production of ethanol, wet ball milling is the process used, because of its versatile process. It produces more products than dry ball milling, but in terms of efficiency, capital, and operating cost, most ethanol plants in the USA prefer to use dry ball milling process. In other words, dry ball milling is cost efficient in ethanol production than wet ball milling. With the above, you should be
