Grinding is a powdering or pulverizing process using the rock mechanical forces of impaction and attrition. The two main objectives for a grinding process are: To liberate individual minerals trapped in rock crystals (ores) and thereby open up for a subsequent enrichment in the form of separation. To produce fines (or filler) from mineral ...

Jet milling is a standard grinding method for high added-value materials. It is mainly used for abrasive or heat-sensitive materials or when the grinding process has to be carried out in ultra-high purity conditions. Jet mills are commonly used to produce particles from 1 μm to 10 μm in the chemical, pharmaceutical, and mineral industries.

The process of comminution is the crushing and grinding of a material / ore to reduce it to smaller or finer particles. The comminution process reduces particle sizes by breaking, crushing, or grinding of ore, rock, coal, or other materials. The process is most often used in the field of mining and / or mineral processing, where mineral ore is broken down into small …
