Grinding | SpringerLink

Conventionally, many mineral processing plants conduct ore comminution stage by dry crushing, followed by wet grinding and classification steps to achieve target size. However, water scarcity dictates to limit of the use of water in ore processing plants, particularly in the arid regions [ 6, 7 ].

Crushing in Mineral Processing

The products can be extracted immediately after the gyratory crusher as 0-32 mm or 0-63 mm fractions, if necessary; these materials are used when stability is needed for the given construction application. The tertiary stage produces fractions in sizes ranging from 0-2 mm to 16-32 mm. These products are used in asphalt and concrete.
