  • Cement milling Question 1 Page 1 of 26

    Cement milling Question 1. Recently, we have changed the grinding balls in the second chamber of our mill to a lower size balls. The effect is a 10 per cent of reducing in fineness at the discharge of the mill, therefore the efficiency of our separator is better, but we were waiting for an increase in the production, nevertheless it is the same than past periods with bigger balls.

  • Existing Surface Preparation for Overlays Pavement

    It is difficult to make up elevation differences or smooth out ruts by varying overlay thickness. For flexible overlays, HMA tends to differentially compact a rule of thumb is that conventional mixes will compact approximately 6 mm per 25 mm 0.25 inches per 1 inch of uncompacted thickness TRB, 2000 1. Therefore, before applying the final surface course the existing pavement is typically leveled by one
