In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition. Compression and impact forces are extensively used in crushing operations while attrition is the dominant force in grinding. The primarily used equipment in crushing are jaw crushers, gyratory crushers and cone crushers whereas ...

A comminuted fracture is the type of fracture in which the bone has been broken into pieces. If the bone has been crushed or broken into smaller splints, this is also a comminuted fracture. Doctors call a comminuted fracture as the one in which the bone has broken in three or more than three pieces.
