Granite Crushing Plant Price
For practical reasons, crushed granite rock is generally used below ground. The irregular shapes and sharp edges of crushed gravel allows the material to compact together snugly when tamped with a hand tamper or compactor machine. The result forms a hard base strong enough to support fence posts and the surfaces of driveways, walkways and patios.
Decomposed granite is an exception as it is often used to pave walkways and driveways. The sand-like materials mixed with small pieces of granite soften the surface. Decomposed granite is applied loose or with a resin on top that joins the pieces into a solid surface.
Granite Crushing Plant
At some operations, all the granite crushing is accomplished in one step, by a primary crusher. At other operations, crushing is done in two or three steps, with a primary crusher that is followed by a secondary crusher, and sometimes a tertiary crusher. SBM is the global suplier and manufacturer of granite crushing plant. We also customize stone crushing solution according to specific requirements.

The jaw crusher squeezes rock between two surfaces, one of which opens and closes like a jaw. Rock enters the jaw crusher from the top. Pieces of rock, that are larger than the opening at the bottom of the jaw, lodge between the two metal plates of the jaw. The opening and closing action of the movable jaw against the fixed jaw continues to reduce the size of lodged pieces of rock until the pieces are small enough to fall through the opening at the bottom of the jaw.
A gyratory crusher breaks rock by squeezing the rock between an eccentrically gyrating spindle, which is covered by a wear resistant mantle, and the enclosing concave hopper. As run-of-mine rock enters the top of the gyratory crusher, it becomes wedged and squeezed between the mantle and hopper. Large pieces of ore are broken once, and then fall to a lower position where they are broken again. This process continues until the pieces are small enough to fall through the narrow opening at the bottom of the crusher.
Impact crushers, which are also called hammer mills, break rock by impacting the rock with hammers that swing on a rotating shaft. The practical use of impact crushers is limited to soft materials, such as phosphate, gypsum, weathered shales, etc. Impact crushers cannot handle as large a top sized material as jaw, or gyratory, crushers can; however, impact crushers can make a finer sized product.
