What Is Primary, Secondary, and Tertiary Crushing?

Primary crushing is the first stage of material reduction and can sometimes be the only stage needed to generate the desired product for a job. Depending on the setup, primary crushing will take the larger material that has been blasted, excavated, or reclaimed and process it through an impactor, jaw, or gyratory crusher to generate a range of product sizes.
