Empire Abrasive Equipment Company
CAUTION
If your application requires aggressive media, such as aluminum oxide, garnet, or
steel grit, it is recommended that you use optional heavy duty ducting,
reclaimer lining, and DI-CARB or BORON nozzles to prevent premature wear.
Empire strongly recommends using boron carbide nozzles when blasting with
Aluminum oxide, which is the most abrasive media
.
If these options are not included with your system, they can be added. Optional
Rubber curtains for interior cabinet surfaces are also available. Consult your
Empire distributor for details.
4.2 Blast Pattern
The size of the effective blasting pattern varies with the size, type and length of the
nozzle, blast air pressure, and the nature of the work piece. Use the following chart
and diagram as a guide, but be aware that the approximate pattern diameters can
only be determined by considering each case individually.
