Shot and grit blasting has been around for many years, but are we getting the most from our systems? This paper looks at the various adjustable parameters that can and do affect the productivity (yardage), media usage and effectiveness of a blasting operation.

Air flow, pressure and nozzle size all contribute to the efficiency and yardage achievable by a blast pot. Pot and valve design will contribute both positively and negatively to these variables but correct set up is imperative for efficient blasting.

Improvement in pot and valve designs can lead to huge gains for the blaster and with some simple, logical adjustment and/or upgrades the changes recommended here will help you get the most from your pot.
