Classifier feed. A lower CL will allow a longer mill residence time and a finer ball mill discharge. It will also allow already finished products opportunities to be broken further. Hence, the optimum CL will provide a good compromise over grinding and minimization of coarse particles in the mill discharge [6].Mill for the maximum residence time. In horizontal coolers, the bed depth is also important and will vary depending on the pellet diameter. For smaller pellet diameters, it is common to have 15-17 cm of bed depth, and this can increase to 23-24 cm for the larger diameter pellets. Pellet porosity will also affect cooling efficiency.

In this study, the milling of clinker was evaluated by varying the mill speed (24 and 72 RPM), residence time (3 and 5 hours) and grinding media load (30 and 40 ) in a ball mill. The experiment was designed as a three level factorial statistical model.Aug 01, 2008 Residence time distributions (RTDs) were estimated by water tracing in a number of wet overflow ball mills (diameters 0.38 to 4.65 m) producing dense, coal-water slurries. In open-circuit mills of 0.38 m diameter and various length-diameter (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.
