Calcium carbonate
dd GCC, is calcite powder, heavy calcium carbonate is referred to, is composed of carbonate minerals such as calcite, natural marble, limestone milling and. It is commonly used with powdery inorganic filler, has high chemical purity, inertia, is not easy to chemical reaction, good thermal stability, does not decompose at 400 ℃ below, high whiteness, low oil absorption, refraction rate is low, soft, dry, not containing water of crystallization, low hardness abrasion value of small, non-toxic, tasteless, no smelly, good dispersibility. According to the need to provide different size requirements of ordinary superphosphate powder, superfine heavy calcium carbonate, calcium carbonate superfine wet grinding, surface modification of heavy calcium carbonate
Heavy calcium carbonate production process two: Dry production process: first hand selected from the quarry to calcite, limestone, chalk, shell and so on, to remove gangue; and then use the crusher in the limestone coarse crushing mill and other mechanical equipment, and crushed to obtain fine powder, finally uses the classifier to mill out powder classification, meet the size requirements of the powder as product packaging and warehousing, unqualified coarse powder milling machine milling back again. Wet production process: first the dry fine powder suspension in the mill for further pulverizing, dehydration, drying to prepare superfine heavy calcium carbonate ( this method has higher cost ).
Use: Widely used in papermaking industry, plastics industry in composite materials, all kinds of plastic pipe, profiles, plastic products, wire and cable materials, degradable plastics and rubber industry; tire, rubber products, seals products; paint industry in the oily bottom paint, high-grade car surface coating paint, powder paint, water-based paint and other materials products of the filler material in. Papermaking industry: having increased surface gloss, whiteness improvement, improving the smoothness of paper. The plastic composite materials industry: can improve the interface bonding strength of composite plastic materials in plastic and mechanical properties; all kinds of plastic pipe, profiles, plastic products, degradation plastic and wire, cable materials used in play, reinforcing, toughening, improve the luster, improve quality. Rubber industry: the product can improve the tensile strength, tensile, heat resistance, aging resistance, tear-resistant properties. The coatings industry: can increase the coating thickness, improve the coating wear resistance and weather resistance, but also can enhance the rate of powder and powder coating spraying area, it does not contain heavy metals, is not containing a heavy metal powder coatings preferred filler.
GCC superfine processing technology is most classic ball + Superfine Classifier Technology ( the technology from Germany 's latest design ), the main characteristics of the equipment for:
Ball mill: According to German ultra-fine filler level of mineral processing design Optimization of the length to diameter ratio of ball mill Grate plate mill tailing discharging, discharging smooth, free up wear, cylinder body without cooling Liner and grinding medium with high aluminum material, to ensure the purity of the product The grinding medium according to the requirement of products and reasonable ratio, high filling rate, high efficiency Optimization of drive and grinding power matched, maximize energy savings And the classifier to form a closed system, negative pressure conveying, no dust
Classifier: Selection of Germany the latest design of the vertical or horizontal single rotor classifier rotor Superfine Classifier Precise flow control to ensure excellent vertex cut The adjustable flushing flow, improve the efficiency of classification Classification of materials directly into the region to be graded coarse powder mixture Optimization design of low power consumption to rotor Through the different classifier alignment regulating product size distribution, to meet the different technical requirements of the product
Quantitative system: Ball mill feed using precise quantitative system, even if the material density change can also be stable feeding Classifier using precise quantitative feeding system, and with the ball mill discharging interlock, ensure system operation and product size stability Flow regulating valve with flow measurement system for grading, air flow rate and velocity control
Control system: Warehouse and product warehouse of material level device, can realize the automatic control of production line Adopting PLC control flow chart display, lighting operation and error, clear, easy to operate Environmental protection and noise control: The deposited film bag processing, waste gas dust emissions below 20mg / m³ Application of high efficient silencer, exhaust noise < 80dB ( A ) All moving parts are heavy shock absorber
No waste water discharge, the only ball bearing cooling water, can be recycled
