With the help of the mechanical force of the scrubber and the grinding force between the sand particles, the thin film iron and mud impurity minerals on the surface of the quartz sand are removed, and the unformed mineral aggregates are further scrubbed, and then the grading operation is carried out to further purify the silica sand.
Emissions from the production of sand and gravel consist primarily of particulate matter (PM) and particulate matter less than 10 micrometers (PM-10) in aerodynamic diameter, which are emitted by many operations at sand and gravel processing plants, such as conveying, screening, crushing, and storing operations.
After the natural silica sand is classified and filtered by the screening equipment, the qualified products flow into the spiral sand washing machine through the launder or the pipeline. It is fully cleaned, soaked and broken by a screw mixer (for larger muddy and extra-large effect), sandstone is fully separated from impurities and mud.
