                                                                   ceramic steel ball

Ceramic balls are widely used as grinding mediums in the world. Because their properties are excellent such as consistence and reliability . Products of these specifications are manufactured from very high quality chemical zirconia materials, which have quite excellent stability, high mechanical strength resistance to thermal shock. The YNN Ceramic Balls are  ideal choice as grinding mediums.
