Abstract 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.
Radiotracer residence time distribution rtd m ethod was used to invest igate the process of clinker grinding in ghana cement plant ghacem at tema with the objective of determining hold-up and grinding efficiencies of two ball mills operating in close circuit regime.The experiment was conducted using 40ci au-198 radiotracer in liqui d stat e and highly sensit ive nai detectors for.
