What is quartz?Quartz
is one of the main rock-forming minerals, generally refers to low-temperature quartz (α-quartz), which is the most widely distributed mineral in the quartz group of minerals. Quartz in a broad sense also includes high-temperature quartz (β-quartz) and coesite. The main component is SiO₂, which is colorless and transparent, and often contains a small amount of impurities, and becomes translucent or opaque crystals with hard texture.
has a Mohs hardness of 7, which is a mineral resource with very stable physical and chemical properties. The crystal belongs to the oxide mineral of the trigonal crystal system. Quartz block, also known as silica, is mainly used for the production of quartz sand (also known as silica sand), and is also a raw material for quartz refractories and firing ferrosilicon.

What are the uses of quartz powder?Quartz sand
is an important industrial mineral raw material, widely used in glass, casting, ceramics and refractory materials, metallurgy, construction, chemical industry, plastics, rubber, abrasives and other industries.
The main raw materials for flat glass, float glass, glass products (glass jars, glass bottles, glass tubes, etc.), optical glass, glass fiber, glass equipment, conductive glass, glass cloth and special radiation-proof glass.
2. Ceramics and refractory materials
Porcelain blanks and glazes, high-silicon bricks for kilns, ordinary silicon bricks, silicon carbide and other raw materials.
Raw materials or additives and fluxes for silicon metal, ferrosilicon alloy, silicon aluminum alloy, etc.
Concrete, cementitious materials, road construction materials, artificial marble, cement physical performance inspection materials (ie cement standard sand), etc.
Raw materials such as silicon compounds and water glass, fillers for sulfuric acid towers, amorphous silica powder, etc.
The main raw material for foundry sand, abrasive materials (sandblasting, hard abrasive paper, sandpaper, emery cloth, etc.).
High-purity metal silicon, optical fiber for communication, crystal oscillator, piezoelectric crystal, etc.
8. Rubber and plastic
Filler (can improve wear resistance)
Filler (can improve the weather resistance of the coating)
Its internal molecular chain structure, crystal shape and crystal lattice change law. It has high temperature resistance, low thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonance and its unique optical characteristics.
Which grinding mill is suitable for processing quartz powder?
Under normal circumstances, when quartz stone manufacturers choose quartz stone grinding equipment, they usually choose the corresponding processing equipment according to the customer's needs, which is mainly related to the particle size of the finished material.
Generally, Raymond mill
is selected for particle size requirements of 80-325 mesh
, and HGM series ultra-fine mills
are selected for particle size requirements of 325-3000 mesh
When choosing, you can make a reasonable choice according to your own production needs.
The whole production process of the quartz grinding powder production line mainly includes four processes of crushing, grinding, grading,
The grinding process of Raymond Mill
The natural quartz material is sent to the jaw crusher for crushing operation, and crushed into a particle size that meets the feeding requirements of the Raymond mill.
The crushed quartz material is sent to the silo by the elevator, waiting for grinding.
The quartz material in the silo is uniformly and continuously fed to the Raymond mill by the electromagnetic vibrating feeder for grinding operation.
The quartz material is ground into powder by the grinding roller in the machine.
The quartz material after the grinding operation must be Under the action of the blower, it is blown to the separator for sorting.
The unqualified quartz powder is classified by the high-efficiency separator and returned to the Raymond mill for re-grinding.
The qualified materials enter the dust collector for separation and collection. The discharge is the finished product.
The specific advantages of ultra-fine mills used for 1000 mesh quartz stone grinding powder
HGM series ultra-fine pulverizer
1. The HGM series ultra-fine pulverizer
is not only more applicable than other pulverizers, but with the same output and fineness, its price is only one-eighth of the jet mill, and the system energy consumption is only the jet mill. One-third of it.
2. Under the action of the high-pressure spring, the grinding pressure of the grinding roller of the ultra-fine mill can increase 800-1200kg compared with other mills of the same type. The diameter can also reach 6.5 microns, which is difficult for other mills to reach.
3. The superfine mill adopts an overlapping multi-stage sealed grinding device, which effectively reduces pollution and isolates noise. Moreover, its grinding rollers and grinding rings wear more uniformly, and the service life is ordinary Raymond mills. Three to five times as much.
The grinding process of HGM series ultra-fine pulverizer
The HGM series ultra-fine pulverizer makes the material enter the middle of the grinding disc from the hopper, and moves to the edge under the action of centrifugal force and is crushed by the impact of the grinding roller. The crushed material overflows from the edge of the grinding disc, and some fine powder As the hot air flows out of the mill, it is stored in the dust collector, and the coarse powder is sorted by the separator and returned to the grinding plate for grinding, and some coarse particles that have not been carried by the hot air flow pass through the scraper. After scraping out, it is fed into the mill by the external circulation bucket elevator for grinding again. It is such a rigorous and meticulous process that the quartz stone can be ground to 1000 meshes.
