Alumina grinding balls and lining bricks are high grade milling media made by advanced cool isostatic pressing technology (CIP) and sintered at high temperature.
Commonly used alumina ball and lining brick is classified by different grades and applications, say, alumina 92%, 75% and 65%.
With overwhelming merits in higher density ,more regular shape,easily classifying and assorting, superior grinding efficiency and competitive price prior to nature cobble-stones and conventional grinding media,alumina grinding media are excellent for grinding process of ceramic bodies and glaze materials in ceramic tile factory and surface polishing of ceramic bearing application.
Inert alumina ceramic balls are made from bauxite or calcined alumina powder. It is widely used in many fields, including petrochemical, chemical engineering, fertilizer production, natural gas and environmental protection.
Inert ceramic balls are used as topping and supporting materials of catalysts in reaction vessels and as packing in towers.
Inert ceramic ball is a material of high stability, perfect thermal resistance, low water absorption, high compressive strength and perfect corrosion resistance of acid, alkali and some other organic solvents.
Inert ceramic ball also has proven performance of thermal shock resistance (They can stand the change in temperature during the manufacturing process.)
The main application of inert ceramic balls is to increase the distribution spots of gas or liquid in a reactor, and to support and protect the activating catalyst with low strength.
