Product Details

60mm high chrome casting alloyed ball with Cr10-12

Application: mainly used for mining industry, cement plant, power station, etc.

Abrasion: about (10-50) g/t in cement

Characteristics:

Xin nanfang has the unique automatic production line of grinding cylpebs in China, which is independently researched and self-developed by xin nanfang’s R&D center. With the self-developed raw materials and special heat treatment system, xin nanfang’s cylpebs achieve good properties, such as high hardness, martensite or bainite metallographic structure and good wear resistance, etc.
