A high-chrome alloy iron ball with more than 10% chromium plus vanadium-titanium microalloying, giving fine dispersed carbides, hardness above HRC 58 and low wear consumption. The mid-range diameter balances breaking capacity with grinding efficiency, fitting cement mills, fine-grinding chambers for mineral powder and desulphurisation mills in power plants. Standard sizes are Φ40, Φ50 and Φ60 mm, graded to chamber length and feed size. Balls are shot-blasted and visually inspected before packing — free of sand burn-on and shrinkage cavities, ready to charge without reworking.
