1. Jaw crusher The jaw crushers are popular primary crushers for coal. They are often used in mines and quarries where large amounts of coal are mined. The working principle of the jaw crusher is to use compression force to compress coal between a fixed jaw and a movable jaw for coarse crushing.
Types of crusher depend on the feeding method. These are Primary crusher, Secondary crusher and Tertiary crusher. The primary crusher is only for the breaking of large stones into pieces (this means primary crusher is not for the aggregate size material.). Examples of primary crushers are jaw crusher; hammer mill crusher and gyratory crusher.
Cone crushers. Cone crushers are one of the main choices for secondary crushing. A cone crusher is a powerful machine that is used in largescale industries for crushing various types of materials into smaller sizes. It works by applying pressure onto the material and squeezing it against a rotating mantle to create compression and force.
