Product Description

high alumina ball-1high alumina ball-3high alumina ball-5

                Inert Ceramic Ball                     High Alumina Ball                 Alumina Grinding Ball

High density equal to denstone 99 3/4'' aluminum oxide ceramic balls

The Xintao 17 Support Media is equal to Denstone 57 Support media. The are the most widely used as catalyst 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 strength and resistance to thermal shock, this makes them all ideal choice for support of all types of catalyst.
