Crushing and grinding the first process in metallurgy is crushing of ores into a fine powder in a crusher or ball mill.This process is known as pulverization.2.The concentration of ores the process of removing impurities from ore is known as a concentration of minerals or ore dressing.In metallurgy, we concentrate the ores mainly by the.
Chemical and process industries utilize stirred media mills for efficient fine grinding of solids.Stirred media mills, also referred to as stirred ball or stirred bead mills, generally have a good ability to produce fine particles with a relatively narrow particle size distribution.

The first step in making paint involves mixing the pigment with resin, solvents, and additives to form a paste.If the paint is to be for industrial use, it usually is then routed into a sand mill, a large cylinder that agitates tiny particles of sand or silica to grind the pigment particles, making them smaller and dispersing them throughout the mixture.
