OPTIMIZATION OF CEMENT GRINDING OPERATION IN …
The operational controls are also reviewed for optimized mill operation. Every element of a closed circuit ball mill system is evaluated independently to assess its influence on the system. Figure 1 below is a typical example of inefficient grinding indicated by analysis of the longitudinal samples taken after a crash stop of the mill.

Floatation
The tendency of an object to rise up to the upper levels of the fluid or to float on the fluid surface is known as floatation. Sinking is just the opposite process of floatation which means the tendency of an object to go deep down to the lower levels of the fluid. The phenomenon of floatation totally depends on the density of the object placed ...
