There are two critical factors influencing choice of crushing techniques and equipment. Hardness of the rock and abrasiveness. Hardness of the rock is typically measured using the Mohs scale, where talc is rated as 1 (softest) and diamond as 10 (hardest). This scale helps determine what type of rock crusher is needed for the job.
