The following 4 factors affect the blast pattern:
Turning direction of the blast wheels:
ˆ The turning direction of the blast wheel must correspond to the
instructions on the housing (arrow indicating the turning
direction).
Worn blast wheel parts:
ˆ With increased wear of the blast wheel, blades, impeller and
control cage, the blast pattern will change.
Size of abrasive:
ˆ The size of the abrasive affects the blast pattern. With every
exchange of abrasive, the blast pattern must be re-adjusted.
Position of the control cage:
ˆ
The correct adjustment of the control cage is the most
important factor to obtain an optimum blast pattern. The control
cage has a lateral window. The position of the window
determines where the abrasive is fed onto the blast wheel
blades and where it hits the surface to be treated.
ˆ After each exchange of blast wheel parts, the adjustment of the
control cage must be checked and re-adjusted by creating a
blast pattern. The same applies for blasting on another type of
surface.
