4.6 BLAST UNIT – ABRASIVE SEALS
This section refers to Figure 4.6.1 on page 25.
Magnetic abrasive seals are present on all sides of the rectangular opening at
the bottom of the blast housing. These magnets should be charged with a load of
abrasive before the blasting process begins. During the blasting process, they
will attract any loose abrasive onto their surface, thus providing a “seal” to help
contain the high impact abrasive from escaping the blast chamber. The leading
and trailing edges of the blast chamber are equipped with additional brush seals
mounted on the outside of the magnetic seals. The brush seals drag across the
work surface allowing clean air to be drawn inside the 1-8DEZ. The air draw aids
in the cooling and the recycling process.
