Mineral Processing

Crushing is commonly a dry operation, and it can be carried out in several stages (e.g., primary, secondary, and tertiary crushing), although the first stage of breakage is the only crushing step always present in modern comminution circuits. The reason for two or three stages of crushing is because of the limited reduction ratio that it is ...
