                                                                              About us
Shandong Shengye Grinding Ball Co., Ltd specializes in the production of mill ball for ball mill. Staff are trained and selected by strict overseas technology . The quality of steel ball is consistent and the specifications are complete. The annual output of diameter DIA 20MM-DIA 150MM mill ball is 100000 tons.
At present, most of the grinding media used in cement plants are mainly high chrome mill ball. With the continuous development of the cement grinding process, the specific surface area and fineness requirements of the cement are more and more favorable, which is especially important for the cement plants to correctly select the grinding meida.
Our company's high chrome mill ball with hardness above 60HRC and impact value ≥4.0J/cm2, The high wear resistance not only improves the grinding efficiency, reduces the times of stopping mill, but also prolongs the clearance period and reduces the labor intensity of the workers. It is important to increase mill output, ensure abrasive quality, reduce power consumption and consumption of the high chrome mill ball.
