Silica sand, also known as silica or quartz sand. It is a refractory particle with quartz as the main mineral composition and particle size of 0.020mm-3.350mm. According to different mining and processing methods, it is divided into artificial silica sand, water washing sand, scrubbing sand, selected (flotation) sand and other natural silica sand. Silica sand is a hard, wear-resistant and chemically stable silicate mineral. Its main mineral composition is SiO2. The color of silica sand is milky white or colorless translucent, hardness 7, brittle without cleavage, shell fracture, grease luster, relative density 2.65. Its chemical, thermal and mechanical properties are obviously anisotropic, insoluble in acid and slightly soluble in KOH solution, Melting point 1750 ℃. The color is milky white, light yellow, brown and gray. Silica sand has high fire resistance.
Silica Sand Recovery Processing
This setup is for the silica sand process, the size range of the silica sand is 0-2mm.
The Flowchart Explanation
The raw bin+electromagnetic feeder for feeding materials to the high-frequency vibration screen automatically, you only need to load the materials to the raw bin by truck or excavator or else as you want.
The high-frequency vibration screen is for separating the silica sand size 0-2mm to the attrition scrubber washer, +2mm will be the waste sand and move away by the belt conveyor.
The attrition scrubber washer is for washing the much sticky clay, then to the spiral wash machine wash again to make sure the materials are cleaner.
The slurry pump transports the clean materials to the spiral chute to separate the silica sand from other heavy materials.
The wet plate magnetic separator is for separating the magnetic minerals in the silica sand, making the silica sand more purity.
The capacity for this washing plant can be customized as per request such as 10tph, 50tph,100tph, etc.,
Notes： If the materials are not much sticky, will not need the attrition scrubber washer or spiral wash machine, and the quantiTy of the machines just for your reference, will depend on your capacity.
The spiral chute will normally make two phases, the concentrate from the first phase spiral chute will to the second phase to concentrate again, that will make sure a higher grade and also release the workload of the magnetic separator.
