One way to prevent cement from ending up in landfills after its shelf life is to regain its activity and reuse it as a binder. As has been discovered, milling by planetary ball mill is not effective. Grinding by collision is considered a more efficient way to refine brittle material and, in the case of cement, to regain its activity. There has been considerable research regarding the …

the effects of mill rotational speed, ball filling level, slurry filling and ball sizes on milling kinetics were explored and analysed using the attainable region (AR) technique. The outcomes of the simulations showed that a finer product is achieved when small balls are used.
Stirred Mill - an overview | ScienceDirect Topics
The attrition mill agitator rotates at speeds ranging from 60 rpm for production units to 300 rpm for laboratory units and uses media that range from 3 to 6 mm while ball mills use large grinding media, usually 12 mm or larger, and run at low rotational speeds of 10–50 rpm. Power input to attrition mills is used to agitate the medium, not to ...

Fig. 3 shows the normalised power draws for Cases A-D at different filling levels. The power draw of the drum was calculated by accumulating the torque on the mill surface and then multiplied by the rotation speed. The power draws increase almost linearly with filling level as the drum needs more energy to lift more particles.
