Crushing and Grinding of Ores or Pulverisation of Ores : The ores generally occur in nature in the form of huge lumps. These lumps are broken into small pieces with the help of grinders or crushers so that the chemical changes which have to take place later on may become convenient. This process is called crushing, which is done by jaw crushers.

A jaw crusher is a machine that breaks down large rocks into smaller pieces of rock, gravel, or dust. It does this by placing two jaw plates perpendicular to each other and squeezing the rock between them until it is broken into small pieces. A stationary jaw plate and a movable jaw plate control the movement of these jaw plates.
