Residence time distributions (RTDs) were estimated by water tracing in a number of wet overflow ball mills (diameters to m) producing dense, coalwater slurries. In opencircuit mills of m diameter and various lengthdiameter (L/D) ratios, the mean residence times of solid were also determined from measured mill holdups. Holdup increased with increased mill feed rate, but the ...

Wet Ball Mills are Ball Mills that are used widely in the ore beneficiation industry,as well as the building material industry such as glass.. During the producing phase, the material and water are mixed together to grind in the ball mill. Under the effect of the flowing water,the material will get a better flow ability so the processing capacity will be higher.
