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?
