As Patton pointed out: 

"I've found the most critical thing when blasting is moisture in the
air.  Keep the air dry and the media will work."

He's very right.  It doesn't take much to clog the pick up and or the 
gun.  I'm constantly having to clean my pick up tube, suction line and 
the gun.  Sometimes you can put your thumb over the nozzel and press the
trigger to blow air out the pick tube.  Other times you need to take it

You also need to agitage the sand some.  I end up shacking my cabinet or
pressure blaster to agitage the sand.

TP tools has a special pickup tube - I believe it's supposed to agitate the 
sand a little:
