ABSTRACT:
Blast cleaning with at least two types of abrasives employing a blasting apparatus having at least a first and a second closed blasting pot connected to a conveying line and the conveying line and each blasting pot are connected to a source of compressed gas by a differential pressure metering system. The differential pressure metering system provides a differential pressure between each blasting pot and the conveying line enabling blasting media in each pot to pass from each pot through a variable size orifice to the conveying line. Each blasting pot can be operated independently of each other enabling varying proportions of different types of blast media to be released in the conveying line and blasted from a nozzle to clean a solid surface.
