Features and application of superfine quartz powder and its grinding equipment

    Superfine quartz powder has unique physical and chemical properties and play significant role in many areas. Its high temperature resistance, small thermal expansion coefficient, highly insulated, corrosion resistance, piezoelectric effect, resonance effect and the unique optical properties, is a prominent role in many high-tech products, especially in aviation, aerospace, electronics, machinery and IT industries.

    Superfine quartz powder have following characteristics: 1. significantly improved resistance performances of compressive, flexural, impermeability, corrosion, impact and abrasion; 2, with water retention, to prevent segregation, bleeding, significantly reduced the resistance of concrete pumping; 3. improve the compactness of castable refractory materials. When coexist with the Al2O3, easier to be mullite and achieve high temperature strength, strong thermal shock resistance.

    The use of ultra-fine quartz powder: 1. in the field of coatings and fillers: quartz powder with good scattering and extinction effect, and relatively low density, brightness up to 92-95, and bright color, will be substituted in industrial applications instead of traditional reflective glass beads and used in paint where the skid resistance has been greatly improved;

    2. In the nylon casting, resin casting industrial production, often using superfine quartz powder to reduce the cooling casting shrinkage ratio; ultra-fine silica powder added in nylon and all resin systems, can reduce the shrinkage ratio of the resin during cooling;

    3. In glass and metallurgical industrial manufacturing and so on, the use of ultra-fine quartz powder scattering and good extinction capacity, can manufacture optical glass instrument, conductive glass and various packaging cans.

    4. In casting industry, quartz powder would be used as an additive and flux to reduce shrinkage ratio of cast during cooling, and the use of high silicon content of quartz powder to produce silicon alloy in metal smelting.

    Ultrafine mill plays an important role in the processing of ultra-fine grinding of quartz, to provide efficient, high capacity, energy saving equipment for ultrafine grinding of quartz, also produce quartz powder with different fineness for customers, further expand the application fields of ultra-fine quartz powder.

    Guilin Hongcheng has a very rich experience in production and grinding technology base in the field of ultrafine grinding mill as a professional mill equipment manufacturer experts, has develop a high efficiency and energy saving mill equipment after twenty years of painstaking research which is HLM vertical mill.

    HLM vertical mill is a type of mill combined with drying, grinding, classifying and conveying. HLM vertical mill have many features as following: high efficiency grinding, lower power consumption, bigger feeding size, easier product fineness adjustment, simple technological process, small footprint, low noise, less dust, easy maintenance, low operating cost, less wear-resistant material consumption, etc. It can widely used in electric power, metallurgy, cement, chemical industry, non-metallic minerals and other industries. Mainly used in grinding materials as cement raw material, clinker, and lime powder for desulfurization of power plant, slag powder, manganese ore, gypsum, coal, pulverized coal ash, barite and other materials, it can provide more professional grinding technology insurance for ultrafine grinding of quartz.

    For powder enterprises, this vertical mill equipment has small footprint, only 50 percent of the ball mill, the terrace can be arranged, the construction cost is very low, all those directly reduce the company's investment costs, and the whole device adopts PLC automatic control system which can achieve remote control, simple operation, easy maintenance, can greatly reduce labor costs, it is a beloved quartz ultrafine mill equipment.
