Bluestone is the most widely distributed gray or grayish-white sedimentary rock (about 15% of the lithosphere) in the crust, and is the most important component of carbonate rocks. Bluestone is widely used in living room tables and tables or cabinet counters after being cut into plates by masons from deep mountains. Compared with natural marble, it has the advantages of calcium carbonate, pollution-free and radiation-free. Bluestone is also an ideal material for construction industry, widely used in highway, railway, construction sand and so on.

Material processing technology

The newly mined large block of bluestone is fed into jaw crusher by vibration feeder for initial breakage, and the crushed material is fed into impact crusher for medium and fine crushing. The crushed bluestone material is fed into vibration screen by impact crusher, and the material that meets the granularity requirement of finished product is fed into bluestone by conveyor. Sand machine, materials that do not meet the grain size requirements are returned to the impact crusher for re-crushing.

The bluestone sand making machine has the function of crushing and shaping bluestone. The bluestone material after shaping by the sand making machine has excellent grain shape and good gradation. The material coming out of the bluestone sand machine is sent by the conveyor to the sand washer for washing treatment. The finished bluestone material can replace the natural sand stone. According to the actual situation in production, dust collectors and other equipment can be configured to reduce the air dust pollution in the production site.
