Produce all kinds of ceramic balls used as covering and supporting materials. ISO , SGS inspected
Professional manufactor for inert ceramic ball , alumina ceramic ball, Refractory ball and all kinds of water treatment ceramic ball.
Inert ceramic balls used as covering and supporting materials of catalysts in reaction vessels and as packing in towers, are widely used in petroleum, chemical engineering, fertilizer production, natural gas and environmental protection.
Introduction: Ceramic balls are widely used support media in the world because of their excellent consistence and reliability. Products to these specifications are manufactured from very high quality chemical-porcelain clay materials, which has quite excellent stability, high mechanical strengthand resistance to thermal shock. This makes them all ideal choice for support of all types of catalyst.
