Total granulation time

Nevertheless, the acquisition of a sufficiently detailed body of physical information can allow a formulator to go far beyond the mere ability to cope with crises when they develop at unexpected times. For a well-understood system, it is theoretically possible to design an automated or semi-automated manufacturing scheme for which the processing variables would be appropriately controlled so as to minimize the possibility of batch failure. Materials passing the hurdles of physical test specifications would be totally predictable in their performance, and they could therefore be blended, granulated, dried, compressed, and delivered into containers without operator intervention. 

Rock-equilibrated water was produced by allowing distilled water to be in contact with granulated gray hornblende schist for a period of several days. The solution produced was filtered through a 0.4 pm NUCLEPORE filter before use. Analysis of the resulting solution showed that rock equilibrated-water contained 48 mg/L total solids (dried at 180°C). The E of the solution was measured to be 0.275 V. The pH of the gray hornblende schist equilibrated water was measured to be 7.6 at the time of the first adsorption experiment. Thereafter the solution pH was maintained at 7.5-7.7.
