80% Alumina Ball for Ball Mill High Alumina Ceramic Grinding Ball
Alumina grinding ceramic balls Description
Alumina ceramic balls use bauxite, roller powder, industrial alumina powder, high-temperature calcined alumina powder and other materials as raw materials, through batching, grinding, powdering (pulping, mud making), molding, drying, firing, etc. Possessed with high density, high hardness, low wear, good seismic stability and good corrosion resistance, the products are the most ideal medium for grinding glaze, blank and mineral powder processing, and are used as the grinding medium of ball mill in ceramics, cement, paint, refractory, inorganic mineral powder and other industries.
