The Wheel Unit
How the Blast Wheel Works

Abrasives from the overhead storage is fed into the centre of the wheel unit which is rotating at high speed. A cast alloy impeller rotates with the wheel and carries the abrasive to an opening in the stationary control cage, from where it is discharged on to the bladed wheel.
At this point, the abrasive is picked up by the inner ends of the throwing blades and is rapidly accelerated as it moves to the outside of the wheel.
