Research on prediction model of ore grinding particle size

The prediction of grinding particle size is an effective measure to optimize the grinding process. Cassiterite polymetallic sulfide ore and lead-zinc ore, as the research object in this paper, their particle size prediction mechanism are studied based on the drop weight test, batch grinding test, the theory law of media motion in ball mill and population balance model.

Factors Influence Ore Grinding Mill Efficiency JXSC Mining

10/05/2019· The finer the grinding particle size is, the higher the grinding efficiency is, and the lower the steel ball consumption is. At present, “more crushing and less grinding” is one of the main principles of concentrator design and production. Take a gold mine as an example, reducing ore particle from -15mm to -10mm improve the grinding efficiency from 1150 tons per day to 1500 tons per dayОнлайн-запрос

What is Grinding in Mineral Processing? Minerallurgy

It is designed to reduce the size of ore pieces to the liberation size of useful minerals. Otherwise to an optimal size that allows separating useful minerals from the gangue. Definition.
