Silica sand is produced by a series of crushing and sand-making treatment of large pieces of quartz stone into finished sand of various specifications. The silica sand production line equipment recommends jaw crusher, cone crusher, vertical shaft impact crusher (sand making machine) and wheel bucket sand washing machine etc.
1. Coarse crushing machine:
The texture of quartz stone is very hard, and the efficiency of sand making directly is not high, and the damage to the sand making equipment is relatively large, so we need jaw crusher as coarse crushing equipment. The primary crushing of the jaw crusher can make all kinds of block-shaped quartz stone uniform in particle size, which can meet the requirements of the feed opening of the sand making machine, with large output, large crushing ratio, uniform product particle size, and low equipment price and low investment cost.
2. Medium crushing machine:
The cone crusher is adopted, it has new crusher structure and optimized laminated crushing cavity, which makes the production capacity large and the crushing efficiency high. In addition, it also has the characteristics of automation and intelligence, high production safety and good environmental performance. It is suitable for hard materials and high output requirements.
3. Fine crushing machine:
Adopt sand making machine as the fine crushing equipment. The feeding size is below 50mm, and the output size can reach 0-5mm. It is more suitable for shaping and sand making of silica sand. It has a variety of cavity types. Higher efficiency, energy saving and environmental protection, and the finished product has a uniform particle size, the particle size is about 30 mesh, and the needle flake content is low.
If silica sand is to be used as a substitute for river sand, its own hardness and toughness need to be improved. The finished silica sand processed by the silica sand processing plant has more stable performance, no cracks and fine lines, and the mud content is effectively controlled. The plasticity index In line with national regulations, the finished product has no segregation of coarse and fine particles.
