Plastic Media Blasting for Powder Coating Removal
). The original PMB systems were little more than sandblast pressure vessels, modified with 60-degree cone bottoms to accommodate the flow characteristics of the plastic blast edia. The relcaim systems for the media were typically the same type used for steel-shot reclaiming. Although they had tremendous
