Question

Limestone (calcium carbonate) particles

arestored in 50-L bags. The void fraction of the particulatematter


is .30(liter of void space per liter of total volume) andthe


specific gravity of solid calcium carbonate is 2.93.


a) estimate the bulk density of the bag contents


(kgCaCO3/liter of total volume)


b) estimate the weight (W) of the filled bags. State whatyou


are neglecting in your estimate.


c) the contents of three bags are fed to a ball mill, a


devicelike a clotes dryer containing steel balls. The


tumblingaction of the balls crushes the limestone particles and


turns theminto a powder. The limestone coming out of the mill is


putback into 50-L bags. Would limestone fill three bags, notfill


three bags completely, or fill more than three bags.Explain.
