EBE 350 E Operating Instructions
Maintenance
The following 4 factors affect the blast pattern:
Turning direction of the blast wheels:
The turning direction of the blast wheel must correspond to the
instructions on the housing (arrow indicating the turning
direction).
Worn blast wheel parts:
With increased wear of the blast wheel, blades, impeller and
control cage, the blast pattern will change.
Size of abrasive:
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:
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.
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.
