Factors Influence Ore Grinding Mill Efficiency JXSC Mining

Based on the crushing theory, increasing the amount of regrinding sand does not increase the power consumption of the mill, but only speed up the slurry flow. In addition, thick and coarse regrinding speeding up the slurry flow can make the coarse grain distributed more evenly, thus improve the steel ball grinding performance and efficiency.

How to Reduce Steel Consumption in Grinding Mills

In the tumbling mills (autogenous, semi-autogenous, rod and ball) wear is generally expressed in terms of steel consumption per ton of ore ground or per kWh consumed by the mill. When comparing the wear rate of different ores in different types of mills, unit weight/kWh is considered a better measure.

Fine Grinding as Enabling Technology The IsaMill

Worn steel media in the ground pyrite can significantly increase the pre-aeration time needed. In a recent application of the Isamill, the existing regrind mill before gold leaching was consuming 10 t/day of steel balls. This reduced pulp Eh and extended residence time in subsequent pre-aeration and increased cyanide consumption in leaching.

Ball mill Wikipedia

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with balls
