Almost no dryer will get rid of the amount of water an undersized
compressor working triple time will produce.  There is a reason large
capacity cast iron two stage compressors are used.  They have to run
less often and therefor run cooler, which means less condensation in the
compressed air.  Think CFM and not just PSI.  Most large volume blasters
use HVLP blasting to help keep the heat down on the work piece.

I hope that your lungs justify the use of a NIOSH approved respirator
while you are using silica sand!  This is the stuff that will cause
cancer in your lungs, don't just trust a dust mask!  I even use a
resporator when I use my blast cabinet when using silica sand.
