Granite crushed stone crusher
SBM Machinery manufactures the most advanced equipments of granite building aggregate, offering you the full-scale technical support. According to different technological requirements, various types of equipments are combined to meet different technological requirements of clients.
Granite aggregate production plant
Granite is a kind of igneous rock, which is formed from the condensation of magma below the surface. Its main constituents are feldspar and quartz. granite is a kind of good building materials, for it is of hard and dense texture, high strength, weather-resistance, and corrosion resistance, low hygroscopy and beautiful color that can keep for centuries. Granite is rather hard to crush, but easier than basalt. This is because granite has certain brittleness, though with high strength. Thus, in the design of crushing process, flexible design can be considered: if clients have advantages in market price, two-stage crushing process can be adopted; however, in the long run, three-stage crushing process is still the effective way to reduce production cost.
Grantie Aggregate Crushing Process:
SBM manufactures the most advanced production equipments of granite, offering you the full-scale technical support. Granite equipments mainly consist of vibrating feeder, heavy-duty stone crusher (takes place of jaw crusher and impact crusher), vibrating screen, belt conveyor, centralized electric control, etc. Generally, its designed capacity is 50-500ton/hour.
Dust-catcher machine and other equipments can be added to the process as the clients’ needs. This series of equipments is applied to the operations of aggregates of granite & other materials, and manufactured sands. In multiple industries, like hydroelectricity, building materials, highway, city construction, can these equipments play a role. According to different technological requirements, various types of equipments are combined to meet different technological requirements of clients. Jaw crusher and impact crusher are assorted to improve the size of stones (multiphase cube). Though its investment cost is a little more than the mentioned two-stage jaw crushing process, the produced stones are in better size. However, Granite is rather hard to crush, so the resistant parts of impact crusher are abraded seriously, which lead to the high production cost in a long term. On the other hand, granite has certain brittleness, so this configuration is acceptable.
One lamination crusher, like fine jaw crusher or cone crusher, is added between jaw crusher and impact crusher, in order to make the size of stone in good quality, along with the production cost reduced. In such combination, the main crushing operation is finished in primary and secondary crushing processes (lamination crushing); finally, the integer crushing is done by impact crushing. The combined technology largely reduces the remaining materials formed after screening. If the proportion of the remaining materials in the production line is over high, the last crusher will increase the overlap crushing, correspondingly, the abrasion of its resistant parts is largely increased.
The technology combined of Two-level laminating crushing process and tertiary impact crushing process largely reduces the production cost, though make investment cost rise. How obvious the advantage !
