Stone Crushing Industry Crushed stone is a major raw material used in construction, agriculture, and industries with complex chemical and metallurgical processes. Material produced by tertiary stone crusher gives an excellent result in strength and quality by additional cohesiveness of cement mortar, paints and other products.
The broken stone is dumped into a primary crusher where the large rock fragments are broken into smaller sizes. Crushing to the proper size usually occurs in stages because rapid size reduction, accomplished by applying large forces, commonly results in the production of excessive fines (Rollings and Rollings 1996). After primary crushing, the material is run through one or more secondary crushers.
