What are the standards and processing of oil fracturing sand?

In silica sand processing and sand washing plant, Petroleum fracturing sand is a special proppant that must be used in oil production under specific geological conditions. Is this the case with technical standards and production technology?

Spherical oil fracturing sand
Spherical petroleum fracturing sand is made of natural quartzite, quartz sandstone or massive quartz. Its silica content is more than 96%, Mohs hardness is more than 65, gravel diameter is greater than 14 meshes and less than 80 meshes. The crude quartz sand is processed and put into an omnidirectional grinding machine. Under the condition of adding grinding agent, it is grinded for 2-8 hours before grinding. When the material is cleaned and dried so that its moisture content reaches 8-12%, it is then transferred to the drying, separation and iron removal process. Then the polishing machine is selected to add polishing agent for polishing, and the polished material is then processed and packed to produce qualified spheri…

Application of silica sand

In silica sand processing, the unique physical and chemical characteristics of silica sand make silica sand play an important role in the aviation, aerospace, electronics, machinery and IT industry, especially in its internal molecular chain structure, crystal shape and lattice change law, which makes it have high temperature resistance, small thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonance effect and so on. Its unique optical properties play an increasingly important role in many high-tech products.
Silica sand is an important industrial mineral raw material, non-chemical dangerous goods, widely used in glass, casting, ceramics and refractories, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives and other industries. It can be transported by air, by train and by water. 1.Glass: Flat glass, float glass, glass products (glass cans, glass bottles, glass tubes, etc.), opti…
