Crushed Quartz Sand

Crushed Quartz Sand is a sort of quartz molecule shaped by crushing quartzite. Quartzite, also known as siliceous rock, is a hard silicate mineral with stable compound composition and physical properties.

Crush the quartz stone in different pieces and for the best finishing do the blasting by suction blasting. In nature, quartzite exists as quartz sandstone, quartz sand shale and vein crushed quartz sand.

Quartz sandstone is a consolidated clastic rock with quartz clastic content more than 95%, which comes from various magmatic rocks, sedimentary rocks and metamorphic rocks, less weighty minerals, and associated minerals are feldspar, mica and mud minerals, Quartzite shale is separated into sedimentary rocks and metamorphic rocks.

Quartz Sand Price is framed by aqueous process, almost all of which is composed of crushed quartz sand. Always used for suction blasting in quartz sand or silica sandblasting. Quartz sand is milky white, sometimes colorless and translucent, its hardness is 7 on the Mohs scale. It is a significant industrial raw material.

Silica sand or quartz sand is processed by crushing, screening and washing of natural quartz ore. It is for the most part used in glass industry, foundry industry, condiment field, metal silicon production and electronic industry. Suction blasting machine is used for quartz sand.

Suction blasting machines have less material or sand compared to other blasting machines. With the quick improvement of industrial innovation, the demand for silica sand production is increasing step by step, which brings about higher requirements for silica sand production innovation.

Crushed Quartz Sand stones are first sent to jaw crusher for coarse crushing, then to the cone crusher for medium and fine crushing after reasonable screening by the roundabout vibrating screen, and the unqualified materials will be gotten back to the cone crusher for re-crushing after the same screening. The quartz stones that meet the requirements of sand making are driven by the conveyor into the sand making machine for sand making and shaping to acquire 0-5mm silica sand or quartz sand. For effective and good results we can use suction blasting machines or cabinets.

Silica sand processing includes coarse silica sand processing and high immaculateness crushed quartz sand purification. Now, the 2 kinds of silica sand or quartz sand processing solutions

1.) Coarse Quartz Sand Processing

There are three parts of coarse quartz sand or silica sand processing discussed underneath:

• Silica sand is taken care of into the feeder by forklift truck. Belt conveyor is put at the tail of the feeder. Silica sand or quartz sand from the tail is conveyed by belt conveyor to jaw crusher for primary crushing.
• After initial crushing, the coarse material is sent to the fine crusher for further crushing. The fine crushed material enters the vibrating screen to screen out two kinds of materials, the quartz stones sand that meet the feed size of the quartz sand making machine taken care of into sand machines, The return materials that don't meet the feed requirements return for fine crushing.
• Part of the quartzite that was taken care of into a sand machine becomes silica sand. Subsequent to washing by sand washer (optional) and recycling by fines recovery unit, finished quartz sand was accomplished. The other piece of the quartzite returns for crushing again.

2. High Purity Silica Sand Purification

Silica sand washing plant basically includes: quartz stone crushing and sand making, washing, grading, desliming, scrubbing, magnetic separation, flotation, acid leaching and other processes to eliminate the small sum or micro measure of impurities in silica sand and get refined silica sand or high-immaculateness silica sand or quartz sand for glass, ceramics, construction, chemical and other industries.

3.) Acid Leaching

The removal of iron from silica sand by acid leaching is based on the way that silica sand is insoluble in acid (except HF), and the pollutant minerals containing Fe can be dissolved by acid solution, so the iron minerals can be eliminated from silica sand.

After flotation, the immaculateness of silica sand can reach 99.5-99.9%. Assuming the silica sand or quartz sand suppliers in India are further purified, the impurities as spots and inclusions on the surface of silica particles must be treated by acid leaching. As indicated by the requirements of different 99.5-99.9%. for different contamination minerals (Fe, Al, Ti, Cr) of silica sand, the mixed acid leaching treatment with different concentration and ratio is carried out.
