    Wet aggregate will contribute water to the mix and dry aggregate will suck water from the mix. Moisture content for Saturated-Surface-Dry condition is calculated by finding the difference of weight between the Stockpile and the Saturated-Surface-Dry aggregate, then divided by the SSD weight. This is then multiplied by 100

    Aug 17, 1971 raw material processing operations differ somewhat for wet and dry processes, as described below. Cement raw materials are received with an initial moisture content varying from 1 to more than 50 percent. If the facility uses dry process kilns, this moisture is usually reduced to less than 1 percent before or during grinding
