The optimum conditions for talc grinding are similar in the absence or presence of SDS in terms of factors under study, except for solids%. The vital role of SDS, as a grinding aid, is the production of particles with the same fineness or even finer at higher solids % which leads to an increase in the mill throughput.

The tumbling ball mill, a moderate energy type grinding mill, was made of alumina with an inner diameter of 14 cm and volume of about 2000 cm'. Forty percent of the mill pot volume was filled with 2 cm alumina balls and 114 g of the talc sample. Milling was carried out using a rotational speed of 86 rpm (75% of critical speed).

Abstract Talc powder samples were ground by three types of ball mill with different sample loadings, W, to investigate rate constants of the size reduction and structural change into the amorphous state. Ball mill simulation based on the particle element method was performed to calculate the impact energy of the balls, E i, during grinding. Each rate constant correlated with the specific ...

1.. IntroductionMineral ore comminution is generally a feed preparation step for subsequent processing stages. Grinding is most frequently done in rotating drums utilizing loose grinding media, lifted by the rotation of the drum, to break the ores in various combinations of impact, attrition and abrasion to produce the specified product [1].In ball and rod mills, attrition is the main action ...

to produce ultrafine particle size, are the stirred media mills, which are similar to ball mills except they contain an agitator, which supplies the necessary energy to the grounded particles instead of rotation of the vessel. The agitator allows the media to collide with a muchhigher force than is possible in the conventional ball mill [3].
