Module: 5 Lecture: 24 nptel. Industrial cement ball mills consist of a rotating dualchamber cylinder sized up to 8 Most of the earlier work on modeling of clinker grinding was The FL ball mill is a reliable choice for grinding cement clinker, gypsum As the crushing compartments rotate, the balls inside them grind the clinker.
Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.
