B. A gate diagram is a plot of cumulative percent by weight undersize vs. the reciprocal of
diameter, in which the area beneath the curve represents the surface
C. Capacity of crusher in choke feeding is increased
D. Rolling of pebbles/balls from top to bottom of the heap in tumbling mills is called ‘cascading
