Jaw crusher 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.

Jaw crusher working principle 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.Classification is divided into the wet type and dry type classification, the former refers to the material in a liquid medium (generally water), and the latter refers to the classification processed in a gaseous medium (generally air).

Dry-type grading is the only option in areas where water is scarce and dry, and where water is not allowed in the process. Besides, in the cold regions, the application of dry grading is not affected. The dry screening method saves a lot of water, and also eliminates the problem of wet grading and subsequent dewatering, and is an effective energy-saving grading method.
