In the mineral grinding process, a relevant role is played by the ball, whose quality is crucial for achieving good technical and economic goals. The best way to get balls is by mean of rolling technology; both forging and smelting are, nowadays, considered obsolete and expensive processes. Thanks to its technological know-how, Revas Technologies projects grinding ball mills capable to ensure the high quality standards needed for meeting the required mechanical and physical features and the scope of a simple plant management.
