The hammer crusher is suitable for crushing medium hardness stones with less than 200MPA. The impact crusher is suitable for handling brittle materials and has a compressive strength of no more than 350 MPa.
It is the most preferred crusher in the primary stage for crushing materials of different hardness in stone crushing and screening plants particularly, hard and abrasive stone–mineral materials with high silica content.
An HSI crusher is suitable for crushing soft to medium-hard materials, such as limestone, gypsum, lignite, coal, coke, weathered shakes, and phosphate. The horizontal shaft impactor is better suited for softer, less abrasive stone. VSI crushers can handle hard and abrasive rocks, such as granite, gravel, trap rock, and basalt.
