摘要: The invention provides a ceramic grinding body for gypsum mill. the mill is mainly prepared from 62%-83% of Al2O3, 5%-8% SiO2, 0.5%-1.8% Cr2O3, 1%-1.45% TiO2, 1.51%-1.75% MnO, 1.6%-3.4% ZrO2, 1%-3% BaO, 4.6%-7% datolite, 2%-2.8% ZnO, 0.5%-1.1% nano-colloidal silica and 2%-6% cosolvent. small in self-weight, low wear rate capable substantially reducing energy consumption cost, service life can be prolonged; no impurity metal iron ion doped process, thus influence caused to whiteness or strength building powder; also electrostatic adsorption, efficiency easily improved.
