1. Loading and feeding
Steel plates or fabricated components are placed on powered rollers, which move the material into the blasting chamber at a controlled speed.
High-speed turbine wheels (blast wheels) throw steel shot or grit onto the workpiece. The impact removes rust, scale, and surface contamination.
Used shot falls into a collection hopper and is transported by screw conveyors and a bucket elevator back toward the separator.
The separator removes dust, broken abrasive, and other unwanted particles. Reusable steel shot returns to the blast wheels.
The workpiece exits through the outlet, where brushes and air blow-off remove remaining shot. The cleaned surface is ready for inspection, painting, or coating
