modified the vibrating ball mill in 2022, incr easing the retention time of fly ash in the mill. Ronin filed for another patent on this method, and the new product was named Pozzo Slag to distinguish it from the old product, CemPozz. The seven-day strengths of the new product initially exceeded

Sika Solutions for Cement Production

further increased dosage results in shorter time for the cement to pass through the mill. If the mill retention time is reduced too much, the cement is insufficiently ground which leads to increased separator rejects and hence a reduced production rate. Traditional grinding aids are based on amino alco-
