crusher around 1850 and the gyratory conical crusher followed soon after Comparative tests costs and experience have established the gyratory crusher as suitable for large capacity applications and the jaw crusher for more modest primary crushing Both types have been in use for over 100 years The jaw crusher was adapted from simple squeezing
A crusher is a machine designed to reduce large rocks into smaller rocks gravel sand or rock dust. Crushers may be used to reduce the size or change the form of waste materials so they can be more easily disposed of or recycled or to reduce the size of a solid mix of raw materials as in rock ore so that pieces of different composition can be differentiated.
