4.12 Abrasive sealing
Magnetic seals are fitted to the front and the sides of the blast housing outlet and are surrounded by brush
seals. At the rear there is a seal sliding over the floor. The seals are employed to seal the blasting area in a
way to avoid leakage of any abrasive.
The correct height adjustment of the magnetic seals (8
–
10 mm) is very important for optimum functionability
of the machine.
The adjustment is done using the 4 setting screws (one each at the rear wheels and one at the front drive wheel
bracket below the control box).
The height of the brush seals should be maximum 1 mm above the surface. Adjustment is effected through slotted
holes. If the length of the brushes is, due to wear, less than 5mm or they are extremely deformed, the brushes
have to be replaced!
