Rotational Speed And Critical Speed Of A Ball Mi

Rotational Speed And Critical Speed Of A Ball Mi. The mechanochemical synthesis of calcium titanate catio 3, was carried out in a planetary mill by varying the milling time and mill rotational speed at three levels.caco 3 and tio 2 were used as the starting materials. besides size reduction, the caco 3 tio 2 mixture had undergone structural changes, which was affected by the process parameters
