Ball mills tumble iron or steel balls with the ore. The balls are initially 510 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.
Nov 18 2008 Abstract The Ball mill is one of the most important equipment in the world of chemical engineering. It is used in grinding materials like ores chemicals etc. The types of ball mills batch ball mill and continuous ball mill with different grinding media and different design depend on the nature of the input material and the nature of the output which I need.
