Principles of Screening and Sizing
Screen width controls material bed depth which allows material stratification and separation to take place. Should not exceed 4x the deck opening at the discharge end. Ideally you should be able to see the last few feet of media. Expressed as the ratio of allowable percentage of maximum oversize and undersize in the final product.

Crushing
In a cone crusher the stones are crushed with both SPB and IPB as the material moves down through the chamber. The relative amounts of IPB and SPB depends on factors like chamber design, crusher geometry, speed, css, eccentric throw, and others. As the market demand shifts can the crusher operation be modified?
