Vertical Roller Mill (VRM) The power used for the actual grinding process while grinding raw materials, depends mainly on the hardness of raw materials and the type of mill used, ie ball mill or vertical roller mill Typically, the motor of the ball mill consumes about 14 15 kWh/ ton of raw mix whereas the VRM motor uses 7 8 kWh/ ton

grinding media (steel balls) on power requirements and energy consumption of a ball mill With constant mass of the steel balls (20, 30 and 40 kg), the agitator shaft speed was increased from 10 to 100% of the maximum speed, which corresponds to a speed of 50 rpm The power consumption (W) was recorded upon which milling energy consumption

Key words: power draw, cement, dry grinding, ball mill INTRODUCTION Energy is the most important cost item in a cement plant About 60% of the electricity consumption for cement production is used for grinding the raw material and cement clinker (Zhang et

In dry cement ball mills, there are studies done in the past which clearly shows that energy saving make sense reducing 1°chamber ball mill filling degree This threadshore level is considered between 20 and 21% Below that level mill production/consumption curve do not make more sense increasing the specific energy consumption instead of
