Design and Optimization of Ball Mill for Clinker Grinding …
For commercial cement plant ball mill 12 m long, 3.8 m diameter, calculations performed using design equations showed top side steel ball size M = 127 mm; mill speed actual n = 16.6 rpm; grindability G = 1.69 g/rev, for throughput 80 T/hr clinker grinding from ~ 40 mm size down to average 5–6 microns,
