What Is Primary, Secondary, and Tertiary Crushing?

Relying on these many stages of crushing beyond only primary can add great value to a crushing operation. Not only can multiple sizes of product be generated, but often in an open-circuit crushing layout, the flow and processing of material is streamlined and can increase output when compared to a closed-circuit crushing layout.Primary Crushing Mineral Processing & Metallurgy,The term “primary crusher,” by definition, might embrace any type and size of crushing machine.
