Due to the different physical and chemical properties and microhardness of the materials the grindability of materials in raw meals decreases in clinkers the clinker discharged from the cement kiln must be pretreated to reduce its particle size so as toincreasethe output and reduce thepower consumptionof theball mill
Aug 01 2001 typical power consumption for a 5m diameter by 7mlong ball mill is between 25 and 35 mw the actual proportion of this energy usefully used in size reduction is thought to be very low perhaps in the range of 15significant financial and environmental benefits can be obtained byimproving this efficiency even slightly

The effects of changes to the properties of the charge ball fraction ball and rock shape type of ball and rock size distributions and the lower cutoff of the rock size distribution can all be interpreted in terms of their effects on the shear strength of the charge some changes increase the shear strength leading tohigherdynamic angles ofreposeof the chargehigher shoulder positionsandhigher power consumption
Charge behaviour and power consumption in ball mills somechanges increase the shear strength leading to higher dynamic angles of repose of the charge higher shoulder positions and higher power consumption for subcritical speeds for supercritical speeds they lead to lower power consumption due to lower particle mobilityas
Also the ball chip generation from the sag mill was reduced considerably further more a 7 decrease in ball mill power draw from 4843 hp to 4491 hp 3613 kw to 3350 kw was observed this equates to a 24 decrease in ball mill unit energy consumption from1113 kwhton to 843 kwhton less
