Iceland spar, the chemical composition of CaCO3, is a colorless, transparent pure calcite (calcite), with special physical properties, known as special non-metallic minerals. Was first discovered in Iceland, it is known as "ice spar. The highest birefringence and polarizing properties of the minerals of white transparent crystal. Quality calcite crystals produced in the calcite veins and the zeolite calcite veins in basalt. Mainly for the defense industry and manufacture of high precision optical instruments, is also widely used in radio electronics, astrophysics, high-tech fields.
Calcite usage:
Iceland spar with birefringence, often use polarizing prisms, cylindrical cut a certain way, when the prism of the microscope detect the optical properties of the mineral, its quality elements must be: colorless, transparent, internal excluding bubbles or cracks, with a double crystal or distorted by more than 0.5 inch (12.5mm) cube. General calcite for chemical, cement and other industrial raw materials. Calcite flux used in the metallurgical industry in the construction industry for the production of cement, lime. Used in plastics, paper, toothpaste, food additives for additive allowed.
Ice spar mill for superfine powder processing at 6 non-flammable, low hardness, Mohs hardness of brittle materials, such as wollastonite, chalk, limestone, dolomite, carbon black , kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, tired rectorite, diatomite, wollastonite, gypsum, alunite, graphite, fluorite, phosphate rock, potassium ore pumice, etc. more than 100 kinds of materials, fine finished granularity be adjusted between 325-3000 mesh, yield up to 0.5-12 tons per hour.
With the development of the era, especially the development of the ultrafine powder technology calcite after grinding into a fine powder, the more versatile. Use different types of crushers crushing grinding and processing of ice spar to preliminary crushing and processing to a different size, convenient to use the mill for grinding processing. Iceland spar through the different types of mill and then grinding to a different degree of fineness, can effectively take full advantage of the different areas.
