Setting the Wheel
Why set the wheel?

When the blast wheel is properly adjusted and its elements are in good working condition, the full effect of the blast stream will be attained for maximum efficiency.

Control Cage

One of the most critical components in the wheel is the CONTROL CAGE. This governs the direction of the blast out of the wheel and onto the work to be cleaned.
The control cage

As little as 10% mis-adjustment of the "HOT SPOT" can reduce cleaning efficiency by 25% or more!

CORRECT SETTING

In the sketch of a clockwise down blast wheel, the centre of the "HOT SPOT" is located directly below the right hand blade, when in the horizontal position. The location of the "HOT SPOT" is directly controlled by the setting of the control cage opening, which, in this sketch is set at "11 o'clock".
