Grind media distribution calculation for ball mills
The most common types of grind media are sand, talc, slag, limestone, dolomite and iron ore fines. Each has its own unique characteristics that should be taken into account when distributing it in a ball mill. For example, sand is very lightweight and flows easily; however, it can clog quickly due to its high granularity. Talc particles are larger than sand but less dense; therefore they …
