Silica Sand Mining Process
The silica sand mining process is generally crushing, separation, rough selection, selection, winnowing, and dust collection. Silica sand produced by the wet method is divided into ordinary quartz sand and refined quartz sand.
The silica sand is the quartz particle produced by crushing quartz stone. Silica stone is a non-metallic mineral, a hard, wear-resistant, and chemically stable silicate mineral. Silica sand is also an important mineral raw material, widely used in glass, casting, ceramics, and fireproof materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, filter materials, and other industries. However, the silica sand contains soil, which will cause the quality of the quartz sand to be substandard and cause serious economic losses. Therefore, the quartz sand washing production line is required to remove the soil for the quartz sand.
Silica sand mining process
The stone material is initially crushed by the coarse crusher, and then the coarse material produced is transported by the belt conveyor to the fine crusher for further crushing.The finely crushed stones enter the vibrating screen to screen out several parts of sand of different particle sizes.
Silica sand mining process classification
The quartz sand production line is mainly divided into dry production and wet selection production. Dry production uses no water, saves energy, no dust pollution, low iron content in the product, small footprint, and high wet processing production output.
Silica sand mining process performance
The Silica sand mining process has a high degree of automation, low operating cost, high crushing rate, energy saving, large output, low pollution and easy maintenance. The machine-made sand produced meets the national construction sand standard, with uniform particle size, good grain shape and reasonable gradation.
