Buker capacity is generally designed for 1214 hours of full load operation. Let us calculate with 12 hours of operation hours. Coal consumption in 12 hours = 392 X 12 /24 =196 MT. Volume of bunker = 196 X 1000/800 = 245 M3. Take 10% of extra margin on bunker as some of coal stucked on bunker wall surface cannot be used for Boiler.

Mine haultruck capacity is an important factor at primary crusher installations, because it is costeffective to integrate truck cycle time at the crusher station with mine/shovel operations. If a primary crusher dump pocket is undersized and unable to handle the mine's trucks, then operators must slowly meter the ore into the receiving hopper.

The actual capacity of roll crushers is only about 25% of the theoretical value due to voids between particles and loss of speed in gripping the feed particle [4], [5]. Thus the actual capacity, Q = .356 t/hr Crushing Power The required crushing power is a function of Bond work index, capacity and the reduction ratio.
