High chrome mill balls are widely used in powder preparation and ultra-fine deep processing in cement plants, building materials, metal mines, power plants, chemical plants, ceramic coatings, light industrial paper, magnetic materials and other industries.
High chrome steel ball has high hardness, low abrasion, good toughness and less breakage. The hardness of the chrome ball will be further improved during the use, the wear resistance will be enhanced, and the grinding machine production capacity can be improved.

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.
Testing Equipment
Our company has a first-class laboratory, and equipped with advanced testing equipment, such as spectrometer, hardness tester, microscope, drop tester, impact tester, laser cutting machine, etc.,to ensure that our high chrome mill ball from raw material into the factory to the prduction process to the shipment of every link quality control assurance and traceability.
