For any load change, the two flows readjust their positions to deliver the required PA flow. For higher load the bypass damper tends to close to allow less flow for preheating of raw feed and the PA damper to the mill opens more to take care of the load demand. Some alternative systems for ball-and-tube mill controls are presented in Section 4.4.4.

dynamic response of foundations (Bhatia, 2006). Based on the scientific investigations carried out in the last few decades it has been established that it is not enough to base the design only on the vertical loads multiplied by a dynamic factor, even if this factor introduces a dynamic load many times greater than the original one.

Calculation of the power draw of dry multi-compartment ball mills 225 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.
