Description
Technical field
The invention belongs to quartz sand granulating technique field, and in particular to a kind of production method of superfine quartz sand granulation.
Background technology
Quartz sand is a kind of quite varied nonmetallic mineral of application, is the raw material of various industrial products, because its is good
Heat-resisting, decay resistance, and the advantage such as aboundresources, cheap is widely used in glass industry, filler field and
Foundry industry, production organo-silicon compound etc..
Quartz sand is quartz through the broken quartz particles for processing.Quartz is also known as silica, be a kind of quality it is hard,
Wear-resisting, stable chemical nature silicates mineral.Exist with quartzy sandstone, quartzite and vein quartz in nature.Quartz
Sandstone is the chip rock of consolidation, and quartz grains content is up to more than 95%.Using certain crushing technology, silica can be crushed
Into the quartz sand of certain mesh number, for industrial production.
For glass manufacture industry, it is necessary to the mesh number of quartz sand is controlled between 20-120 mesh.Quartz sand particle slightly can excessively
So that glass smelting quality goes wrong, the meticulous meeting of particle causes to produce larger winged material during charging, corrodes kiln.In stone
In sand production process, often because of raw material exploitation, the restriction of processing mode, superfine silica powders more than a large amount of 160 mesh, nothing can be produced
Method is used for glass production.Therefore, it is that one kind has an economic benefit to be roughened and be applied to Improving Glass Manufacturing Processes these superfine silica powders very much
With the production technology of environmental benefit.Therefore a kind of energy-efficient superfine silica powder coarsening technique is sought, for the height of quartz raw material
Effect is using significant.
