Preparation method of special low-density grinding column for cement grinding mill
The invention relates to a preparation method of a special low-density grinding column for a cement grinding mill. The preparation method comprises the steps of with bauxite, alumina powder and the like as main raw materials and chromium oxide, zirconium oxide, calcium oxide, magnesium oxide, ferric oxide, manganese oxide, titanium oxide, silicon dioxide and the like as modified raw materials, adding alumina sol, silica sol and metal salt into slurry at a grinding stage; molding by rolling, isostatic pressing or machine pressing to obtain a green body; and calcining after drying the green body to obtain the low-density grinding column. By virtue of scientific proportion design, strict process control and unique calcining system, the special low-density grinding column disclosed by the invention is low in cost, excellent in wear resistance, lower in power load as comparison with a high-density metal grinding body, suitable for substituting a metal grinding body in cement grinding, iron ore grinding and gold ore grinding and capable of reducing the electric consumption for grinding by 30-50%.
