Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones. The

The Center-Periphery Discharge mill has feed reporting from both ends and the product Get More. Crushing SAG Mill Critical Size Material. This effect occurs mainly in coarse material and does not produce too many fine particles. it can be fed to the SAG mill. In that case the ball mills are fed with a fraction of the SAG mill discharge, as in the original circuit (Figure 1). Get More Operation Of Cement Ball Mill - Then, discharge of ground material performed. Ball Mill Operation -Grinding Circuit Startup & · The grinding circuit operator must ensure that the ball mill runs properly loaded and gives the correct ore grind. A major practical indication of mill loading is the sound made by the mill. A properly loaded mill will have a deep rhythmic roar, while an under loaded mill will have a
