The raw material of quartz stone is sent to the raw material bin by forklift or dump truck, and then evenly fed into jaw crusher by vibration feeder. The material is crushed to about 150 mm in size and transported to cone crusher by belt for crushing. The crushed material is graded by vibrating screen, and 0-5mm material is sent to wheel bucket sand washer through belt conveyor, and then sent to finished product pile after water washing. >30mm material is sent to cone crusher by belt conveyor, and then it is graded by vibrating screen to form closed-circuit circulation. 5-30mm materials are sent to the high-efficiency centrifugal impact sand making machine for crushing by belt conveyor. The crushed materials are graded by vibrating screen. The 0-5mm materials are sent to the finished product pile after water washing. The materials that do not meet the specifications of the finished products are sent to the high-efficiency centrifugal impact sand making machine again to form a closed-circuit cycle. After the materials meet the specifications of the finished products, they are washed and sent to the finished product pile.
Because the quartz content of quartz stone is as high as 94%, quartz crystal is the natural mineral with hardness second only to diamond in nature, and its surface hardness can be as high as Mohs hardness of 7.5. Therefore, jaw crusher, cone crusher, impact crusher and other crushing equipment are usually used for quartz sand making.
1、 Glass: the main raw materials of flat glass, float glass, glass products (glass tank, glass bottle, glass tube, etc.), optical glass, glass fiber, glass instrument, conductive glass, glass cloth and special anti radiation glass, etc;
2、 Ceramics and refractories: raw materials and glazes of porcelain, raw materials of high silica brick, common silica brick and silicon carbide for kilns. Metallurgy: raw materials or additives and fluxes of silicon metal, ferrosilicon alloy and silicon aluminum alloy;
3、 Construction: concrete, cementitious material, road building material, artificial marble, cement physical property test material (namely cement standard sand), etc;
4、 Chemical industry: raw materials of silicon compounds and water glass, filler of sulfuric acid tower, amorphous silica powder;
5、 Machinery: the main raw material of foundry sand, abrasive materials (sand blasting, hard abrasive paper, sandpaper, abrasive cloth, etc.);
6、 Electronic: high purity metal silicon, optical fiber for communication, etc;
7、 Rubber, plastic: filler (can improve wear resistance);
8、 Coating: filler (can improve the weatherability of coating). Commonly used packaging is 25kg and 50kg
Application in building materials industry:
The main material of quartz stone is quartz. The combination of rich colors makes it have the texture of natural stone and beautiful surface luster. Quartz stone table top has various colors. Gobi series, crystal series, marble series and twinkling star series are more distinctive. It can be widely used in public buildings (hotels, restaurants, banks, hospitals, exhibitions, laboratories, etc.) and family decoration (kitchen table, washstand, kitchen wall, dining table, tea table, windowsill, door pocket, etc.), which is a non radioactive pollution and can be reused Environmental protection, green new building interior decoration materials. After being crushed, quartz stone can also be used as building aggregate, which can be used in concrete, cementitious material, road building material, artificial marble, cement physical property test material (i.e. cement standard sand), etc.
