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.

The ball mill consists of a cylindrical porcelain jar with a tight lid. The material we want to triturate is placed into the jar along with 99 times as much lactose and the extremely hard "balls" which will grind the material. (Actually we now use small cylinders rather than the balls used originally. Small cylinders grind better than balls.)

Compared with the micron-level HNIW obtained by four times of recrystallizations, the particle size grading mechanical ball milling method of grinding balls minimizes the particle size of the HNIW. The prepared nano-level HNIW has an average particle size of about 200 nm and has the advantages of narrow distribution, low mechanical sensitivity ...
