Our SAG mill strategies automatically adjust feed rate, mill speed and water addition to reduce upsets, eliminate grindouts, protect liners/lifters, and increase tonnage . We maintain desired operating conditions by constantly monitoring bearing pressure, mill power, recycle pebbles, mill density, charge toe and mill acoustics,
Also with low ball charge slurry pool will reduce grinding efficiency. Beside lower ball charge will increase P80 of ball mill because of less number of impacts but mean residence time will increase by lower ball charge because of more volume to occupy. I think at last in .
grinding media needs to be considered as this can lead to contamination of the dispersion (1215). The optimum milling process parameters,, the milling time and the milling speed, to prepare pigment dispersion depends on a number of factors including the pigment hardness,

Denmark (trade named Cemax Mill). Horomill is suitable for grinding raw meal, cement and minerals, whereas Cemax Mill is mainly for cement grinding. The mill can be used for pregrinding and finish grinding. This millsystem claims to have advantages of ball mill, roller mill and roller press in terms of reliability and energy savings.
result in mills operating at optimum speed if low media charge or low consistency is used in the mill. The use of lifter bars welded or bolted to the mill cylinder in unlined mills reduces media slippage in mills whose rotational velocity is slow. Lifter bars are recommended when the grinding media charge is below 45 percent of the mill volume.

• Energy consumed in lifting the balls is utilized for grinding job • When the ball mill is rotated, the balls are carried by the mill wall nearly to the top • Balls are released by the gravitational pull and drop to the bottom and picked up again • Centrifugal force keeps the ball in contact with the mill wall.
were used in the grinding process to generate a particle size reduction of the calcium carbonate (CaCO3). To determine the optimum milling parameters the collected test data were used to calculate and evaluate specific energy as well as stress intensity under different milling conditions.
