water-cement ratio uniformity Once a mix design has been developed, sample panels (mock-ups) should be built as references for color and overall surface appearance for every architectural project. Selecting Cement Cement of the same type and brand from the same mill should be used throughout the entire job to minimize color variation (see Fig. 2).
In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.
