An abrasive blast facility reduces blasting costs and environmental contamination by bringing blasting indoors, making possible the use of recyclable abrasives. To make the most of recyclable abrasive, an efficient abrasive recovery system automates the media recovery and cleaning processes.
The Clemco Belt Conveyor Recovery System combines simple, reliable, technology with high quality components for a system that is rugged, durable, and economical. The Clemco BCR system is built in custom lengths to suit existing or new blast rooms. It is engineered to suit rooms of all sizes.
Standard systems include:
The Clemco BCR system features multiple floor collection hoppers installed in a trench in the blast room floor. Partial-area systems can be configured in a single run, in H-, L-, or U-patterns or whatever layout suits the appliction. Floor gratings, flush with the blast room floor, cover the hoppers. Abrasive falls through the grating, into the hoppers, through a metering tube, falling on the 12-inch wide belt below. The distance between the hopper metering tube and the conveyor belt is set for the optimal media flow-rate which prevents belt overload.
A 2-HP drum motor drives each belt, conveying material to the bucket elevator for transfer to the abrasive cleaner. Angled rollers beneath the belt form a V-shape support to contain the abrasive on the belt. Abrasive drops off the belt into the bucket elevator hopper. Sturdy buckets raise the abrasive to the air-wash cleaner, where the abrasive is separated from dust and debris. Debris falls into a waste container, dust is drawn into the dust collector, and reusable, clean abrasive falls into a hopper atop the blast machine.
Collection hoppers are constructed of rugged 10-gauge steel making them ideal for wear resistance and long life. For each run of hoppers, a heavy-duty, multi-ply, endless belt is powered by an electric drum motor. The belt is fabricated to resist wear. The durable bucket elevator assembly has a reinforced PVC belt and tough but lightweight polyethylene buckets.
