Ball milling,hearforce dominant process where the particle size goes on reducing by impact and attrition mainly consists of metallic balls generally zirconia zror steel balls, acting as grinding media and rotating shell to create centrifugal force.in this process, graphite precursor was breakdown by randomly striking with grinding media in the rotating shell to create shear.

The milling process definitions cutting speed,vndicates the surface speed at which the cutting edge machines the workpiece. effective or true cutting speed, indicates the surface speed at the effective diameter dc ap.this value is necessary for determining the true cutting data at the actual depth of cut.this isarticularly important value when using round.

In all ore dressing and milling operations, including flotation, cyanidation, gravity concentration, and amalgamation, the working principle is to crush and grind, often with rod mill or ball mill, the ore in order to liberate the minerals. in the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.
