Crushing equipment commonly used in sand and gravel aggregate production lines
Crushing equipment can be generally divided into extrusion and impact according to the working principle. The output of extrusion crushing equipment has a low content of stone powder and a large proportion of flake particles. Common equipment types mainly include jaw crusher, gyratory crusher & cone crusher. Impact crushing equipment is relatively simple in structure, has a large operating crushing ratio, and has good product particle shape. Common equipment types mainly include impact crusher, hammer crusher, vertical shaft crusher, etc.
