Abrasion resistance of aluminosilicate refractories for
May 01 1978 · An investigation was carried out of the abrasion resistance of aluminosilicate refractories for rotary kilns by two methods viz. on a sandblaster and on a grinding wheel. The first method gave more precise and reliable results. The test conditions on a sandblaster are optimal with an air pressure of 1.5 kgf/cm2. The results of the investigation of the abrasion resistance and its variation
