I'm not an expert. I have messed around with some sandblasters over the years. I will say that trying different air pressure can help. Start around 40 PSI and work your way up. Air pressure is about the only adjustment the simple bucket style blaster has.
What type of abrasive are you using?
Sandblasters are deceptively simple but, the details to make them effective and efficient are complex. That's why cheap ones are $30 dollars and expensive ones are $30,000.
Water jet blasters make dust control easy. In addition they give your grit a boost as wet media is heavier than dry media so it looses less momentum between the end of the nozzle and the work surface. Which can help or hurt depending on what you trying to accomplish.
