A system for the removal and recovery of spent abrasives from an abrasive blasting system including a floor having a collection channel with a longitudinally extending frame thereon. The frame supports a grating and has rails for slidingly engaging a reciprocally driven drive member and a blade support member. The blade support member has a plurality of bars laterally crossing the frame on which are supported a plurality of sweeping blades. As the drive member reciprocally slides along the rails it engages the blade support member causing the blades to sweep the abrasives toward the channel. The blades are adapted for pivoting and will pivot as the drive member reciprocates so that they engage the abrasives when moving toward the channel, and pivot away from the abrasives when moving from the channel. A suitable abrasive removal device may be used in the collection channel to carry the abrasives to a desirable collection location.
