The manual metal mold is widely used in foundries to produce casting chromium grinding media ball, including low, medium and high chrome contents. Balls size from dia30mm to 150mm. This kind of metal mould is easy to operate and investment costs are low. Metal mould adopts the chilling process to get refined microstructure.
Ball mill is widely used in building materials, mineral processing, cement, thermal power generation and fertilizer production of the main grinding equipment, grinding ball is the largest consumption of wear-resistant parts. Therefore, with the continuous development of key industries such as building materials, the demand for grinding balls will increase greatly. At present, ordinary forged […]
The AUTOMATIC SAND-COATED METAL MOULD PRODUCTION LINE adopts the advanced sand-coated metal mold producing process, which can significantly improve the mechanical properties of castings, improve the appearance quality of castings, reduce the machining allowance of castings & the labor intensity & the number of workers, minimize the production of safety hazards.

The results show that hardness of […]
ABSTRACT: The heat treatment process of high chromium grinding ball produced by sand coated iron mould casting process was researched. Shrinkage and porosity defects have not been discovered after cutting along the diameter of grinding ball. The grinding ball in cast state has poor mechanical properties. Mechanical properties of grinding ball significantly increase after heat treatment After heat […]
