All kinds of paper or processing paper are filled with ultrafine heavy calcium, kaolin and other powders, they give the paper special properties, so that the paper has a certain coverage, smoothness and fitness, while replacing the log fiber, can greatly reduce the cost.In addition to paint added powder, including kaolin, talc, heavy calcium carbonate and barite.
Among them, heavy calcium and calcined kaolin by wet ultra-fine grinding, can produce high value-added products with a broad market, and the market demand is huge.
At present, in the large mixing mill and tower mill, the need for a low proportion of grinding medium.Among them, 2.7-3.2g/cm3 is the most, mainly composed of alumina ball and composite ball, and the composite ball has high and low zirconium content.
1. 0010010 nbsp;The catalyst preparation technology in coal direct liquefaction project requires a large ultrafine mixing and grinding mechanism to prepare submicron pyrite slurry.
2. 0010010 nbsp;The composite ball has been popularized and applied in the non-mining industry for a long time.
