screening and classification of ores - goldencash

Ore screening is to screen and separate the material with a particle size below 250 um, among which the classification of materials below 10 um is called superfine classification. Ore classification affects the crushing and grinding process and controls the particle size of the final product, which in particular plays an important role in product quality.
