  • Optimization of continuous ball mills used for finish

    The L/D ratio of the ball mill was varied in four steps of 1.75, 2.1, 2.79 and 3.49, and the ball charge filling ratio was varied in three steps of 15%, 20% and 25%. The experiments clearly indicated that the optimal L/D ratio and the optimal ball charge filling ratio are different for each feed fineness.

  • Preventing Slump Loss

    Apr 10, 2013Cement producers put gypsum in cement mills with the clinker for grinding. Gypsum is a source of sulfate, which reacts very quickly with the tricalcium aluminate (C3A) so that the cement does not flash set. C3A, without the sulfates, reacts within minutes, and would not allow the concrete to
