Since cement is usually loaded pneumatically, the amount of air that is integrated in the cement must be accounted for to avoid overfilling of the silo. The following data can be used to determine the silo capacity needed. 1 Barrel of Cement = 300 lbs of blown in, or "fluffed" cement. 200 Barrel Silo – Loaded Capacity of 60,000 lbs / 30 tons

Optimization of mill performance by using online ball and pulp measurements Soon after a stop, a mill is a dangerous place to enter for the personnel tasked with taking measurements or

measurements typically not reliable – Horizontal dimensions can be measured accurately, but vertical dimensions are potentially very inaccurate – Vertical dike height is only as good as the lowest elevation point on the top of dike (i.e., spill-over elevation) – For a 500' x .

The mill load that is the volume of charge in the mill is the principal determinant of power draw. Estimation of the ball load that is mixed with the cement charge is difficult and can be highly erroneous. So direct measurement must be taken for calculation of mill load. A direct measurement of the load entails the crash stopping of
