Calcium as human important minerals, metabolic balance to sustain life and health play a crucial role, in addition to the daily intake of calcium from foods, calcium supplements can also be achieved through calcium balance. CCTV science and education channel from the program we can see, mainly from calcium carbonate, oyster shell. Wherein when the body’s calcium carbonate as a calcium supplement absorption rate of up to 39%, second only to fruit acid soluble calcium, has become the largest forms, the most widely used of calcium supplements.
Calcium carbonate is an inorganic compound, mainly in the limestone and calcite, limestone (common name bluestone) of calcium carbonate, CaCO3 content is usually 92-93%. Calcium carbonate into calcium carbonate and calcium carbonate into two categories.
Depending on the fineness of processing calcium carbonate can be used in different industries, calcium carbonate less than 200 mesh can be used for a variety of feed additives, calcium amounted to no more than 55.6% of harmful ingredients; 250 mesh to 325 mesh, whiteness 85 degrees above can be used as a plastic factory, rubber factory, paint factory, waterproof materials plant in Highland and other materials, such as paint inside and outside the paint before; 350 mesh to 425 mesh and a whiteness of 93 degrees or more can be used in the manufacture pinch, the water pipes, chemical field; 425 mesh to 600 mesh, whiteness above 94 degrees can be used to make toothpaste paste, soap; 800 mesh, whiteness above 94 degrees used in advanced rubber products, cables, pvc filler; 1250 mesh, whiteness above 95 degrees for pvc, PE, paint, paint-grade products.
Therefore, to get to meet the different needs of different fineness of calcium carbonate, we need to limestone, marble, calcite refinement process. Shipped from the quarry calcite, limestone, chalk, shells removed gangue, then with rock crusher for coarse crushing, and then give a fine limestone flour mill flour, and finally sorting machine for milling conduct grading, meet the size requirements of the powder as product packaging and storage, otherwise mill grinding again. In line with the required fineness of calcium carbonate in the removal of impurities, heavy metals, after purification, disinfection, filtration, and so the process can be used for medicinal and edible added.
Calcium carbonate, the main production equipment:
MTW MILL
MTW European version of the mill is the Shanghai World state expert absorb European latest grinding technology and philosophy, in the long-term mill on the basis of research and development experience, comprehensive 9518 mill use customer suggestions, after painstaking research out of the latest innovative design mill powder. Excellent aircraft production to meet customer demand for 200-33μm (80-425Mesh) fines.
A, yield: a unique curved-type blade design, material can be oriented facade, the upper roller mill ring, middle and lower can be grinding, uniform wear, while also increasing the effective working area and improve the Yield.
B, good product quality: cage, leaf disc separator, dual configuration options, unique for gas sealing means to effectively prevent “run meal.”
C, low investment costs: blade using split design, simply replace the shovel blade when replaced; blade section made of high wear-resistant alloy materials, long service life, greatly reducing the cost of production.
D, long life: with research institutions to develop wear-resistant alloy of the roller mill ring, it is 1.7 to 2.5 times the life of traditional high manganese steel for a harder material, effectively reduce downtime.
E, high intelligence: electrical equipment using intelligent control system with boot time and run time are automatically stored memory function, which enables remote start, stop monitoring, with operating mode memory function, more convenient.
