Granite crusher is a mining & quarrying equipment used in granite mining or granite quarry, in order to crush the granite rocks to the required specifications.

SBM is a major mining & quarrying equipment manufacturer and supplier in China, our quarry rock crusher is of good quality and service. Granite crusher is the popular products of SBM, the major granite crusher is jaw crusher, impact crusher and mobile crusher etc.

Granite crushing plant is complete set of crushing equipment including vibrating feeder, jaw crusher, impact crusher, cone crusher (optional), vibrating screen, conveyor belt etc. If the clients need high mobility from site to site, SBM mobile crusher is the best choice.

1) The hardness of granite;
2) The average size of the raw granite stone before entering into the crushing system;
3) Requested end product sizes, percentage of the sizes, and their usage;
4) Hour capacity of the crushing line.

For the granite crushing production lines: 30-50tph, 50-80tph, 80-120tph, 120-200tph, 200-300tph, 300-400tph, 400-500tph, we here recommend three proposals:

Proposal 1: vibrating feeder +primary jaw crusher +impact crusher +vibrating screen +belt conveying system +control system
Proposal 2: vibrating feeder +primary jaw crusher +fineness jaw crusher +impact crusher(optional)+vibrating screen +belt conveying system +control system
Proposal 3: vibrating feeder +primary jaw crusher +Compound cone crusher +impact crusher(optional)+vibrating screen +belt conveying system +control system
In the above proposals, the main difference is the secondary crusher: using impact crusher, or using fineness jaw crusher (hydraulic impact crusher), or compound cone crusher.

Notice for the clients:
If the local market has not request of the stone shape, users prefer to use fineness jaw crusher, or compound cone crusher as the secondary crusher. Because for high hardness stones such as granite stone, the quick wear parts cost of fineness jaw crusher/cone crusher is lower than that of impact crusher.

For jaw crusher and cone crusher, the working principle is plate pressing, so the percentage of stones with flaky shape, internal cracks is high.

For impact crusher, it has the functions of crushing and shaping, can make very good cubical shape; the end products are mainly used for highway, water conservancy, airport, civil construction etc. The market prices of stones made by impact crusher is higher than that by fineness jaw crusher or cone crusher; the quick wear parts cost of impact crusher is also high for high hardness stones.

If the market has request for the stone shape, and the users want to reduce the quick wear parts cost. Here we recommend firstly use primary jaw crusher + fineness jaw crusher/ cone crusher as the primary and secondary crushers, take the impact crusher as the tertiary crusher to shaping the stones. This proposal has been adopted by many users, and proved to be workable.

About granite mining and granite quarry:
Granite is a very hard, crystalline, igneous rock primarily composed of feldspar, quartz, orthoclase or microcline accompanied by one or more dark minerals. It is visibly homogeneous in texture. It is the most common plutonic rock of the Earth's crust, forming by the cooling of magma (silicate melt) at depth. Granite is one of the most exclusive stones amongst all building stones. It is widely used as granite kitchen countertops, worktops, granite counter tops, table tops, flooring, etc. in the form of random slabs and tiles.

Large quarry stone through the hopper are evenly sent by the vibrating feeder to jaw crusher for primary crushing. After the coarse crushing, the small stone are sent to impact crusher for secondary crushing via conveyor belts. Then different types of small stone are screened out by vibrating screen. Stones that meet the size requirements are sent to the finished pile through conveyor belt, while other stones are sent back to impact crusher to crush again. Finished size can be adjusted and graded in accordance with the needs of users. Being equipped with auxiliary dust deducing equipment, the crushing plant is more environmental-friendly.

Granite quarry is a pit or some open excavation from which granite is obtained. To obtain granite from a quarry digging, cutting or blasting process is used. This process of obtaining the stone is called quarrying. Once quarrying is done, the processing of granite starts.

Granite quarries are laid out based on the direction in which the granite will break the easiest, providing the maximum benefit that can be attained from the natural seams and structure. By using these natural seams, the maximum yield can be obtained from the quarry deposit, thus reducing the amount of stone produced that is not suitable for use as dimensional granite.
