The scraper floor is designed to automatically recover spent abrasive and contamination back to a bucket elevator. The scraper floor consists of a series of pivoting blades fitted into a movable frame. The scraper modules move back and forth driven by a pneumatic cylinder to reduce running costs. The blades ride up and over the abrasive on the backwards stroke, pushing the abrasive along on the forward stroke. The media is then transported to the abrasive cleaning unit. The advantage of the scraper floor system is its low profile design which reduces or, if floor mounted, eliminates any foundation costs. The system is designed for low maintenance and does not require any tools to remove the blades from the modules for inspection or repair.
