A stone crusher is a mining equipment used in the mineral processing stage. Stone crushers are used at the beginning of the operation to crush raw materials and convert them into smaller pieces.

There are different types of stone crushers, which can be divided into jaw crushers, impact crushers (cobite) and hydrocones depending on the type of use. Impact crushers are used to crush medium-sized minerals (0 to 200 mm) into smaller sizes for various uses such as sand and gravel, concrete, mosaic, asphalt, and the like.
