Achieving particle size reduction with a row cage mill

The mill can achieve a size-reduction ratio (the ratio of feed particle size to final product particle size) as high as 40-to-1 in one processing pass. The cage mill's high size-reduction ratio results from its crushing mechanism: impact rather than compression. While a compression mill, such as a .

Ore Material Particle Size Classification Principle - JXSC ...

Ore classification 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.
