Media Selection
Grinding media selection significantly affects grinding cost and efficiency.
Steel Balls
Forged or cast steel balls (40-120 mm diameter) for ball mills. Chrome-molybdenum steel provides optimal hardness and wear resistance.
Grinding Rods
High-carbon steel rods (50-100 mm diameter, 3-6 m length) for rod mills. Straightness and surface quality affect performance.
Media Consumption
Media wear rate depends on ore hardness, mill speed, ball size and slurry chemistry. WSHT optimizes media selection for minimum cost per tonne.
