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.
