Analysis on Application of case of Raymond Mill in coarse whiting powder processing

According to the different calcium carbonate production methods can be divided into calcium carbonate, calcium carbonate, light calcium carbonate, colloidal calcium carbonate and calcium carbonate crystals.
Heavy calcium carbonate coarse whiting, is made of high-quality calcite as raw material to produce a white powder, it is the main component of CaCO3, insoluble in water and alcohol, with high whiteness, purity, color soft and chemical stability and other characteristics, is the industry with the most of the inorganic filler.
Light calcium carbonate in limestone as raw materials, mainly used in rubber, plastic, paper and paint, ink and other industries as a filler, and can be used for powder, toothpaste, cosmetics, daily chemical products, can also be used in organic synthesis, metallurgy, glass and asbestos production.
In the paint application: TSP is relatively safe and dry hiding power is not high. Not as good as Qinggai whiteness, but also cheap. The light use if used carelessly, easy to cause serious after thickening, the most serious is the coating. The proportion of oil absorption of calcium, alkaline is relatively high. The proportion of calcium carbonate dry hiding power is much higher, the proportion of calcium is white.
By raymond mill and high pressure roller mill can be used for the classification process of calcium carbonate for:
1.200 meshes: can be used for a variety of feed additive calcium content was more than 55.6 and no harmful ingredients.
2.250 mesh to 300 mesh, used as a plastics factory, rubber factory, paint factory, waterproof material factory raw material and exterior wall paint. Whiteness above 85 degrees.
3.350 mesh to 400 mesh is used in the manufacturing of gusset plate, water pipelines, chemical. Whiteness above 93 degrees.
4.400 mesh to 600 mesh: can be used in toothpaste, soap. Whiteness above 94 degrees.
5.800: used in rubber, plastic, cable, PVC whiteness above 94 degrees.
6.1250: PVC, PE, paint, paint products, paper coating, paper surface coating, the white degree in more than 95 degrees. The high purity, high whiteness, non-toxic, odorless, fine quality, low hardness and low.
