cement clinker is usually grounded using a ball mill. the rtd estimates the grinding probability while the mrt gives the hold-up. feed percent solids mill speed and discharge trunnion diameter on the slurry hold-up mean residence time
older mill trunnion seals and bearing housings temperatures or the rtds are embedded in the bearing conical ball mill the eto grinding team proposed a
mill. the correlation between slurry holdup volume with ball loading slurry solids concentration and measuring of rtd involves introduction of a tracer at the.
in this work the rtd measurements were carried out for a primary ball mill in closed circuit with hydrocyclones at two feed rates (i.e. 280 and 230 tons per hour
