ATTENTION!
Abrasive blasting with sands containing crystalline silica can cause seri-
ous or fatal respiratory disease.
Steel blast media: : Still grit or shot can be limited used with CAB-110P and CAB-135P
cabinets (max. mesh size ca. 0,80 mm). Exact max. media mash is depended from materials
specific weight and grains geometry and should be determined with practical tests run by users.
Rubber curtains should be used to protect the cabinet walls from rapid wear .
Sand and Slag: Sand should never be used because of the respiratory hazards
associated with the use of using media containing free silica.
Slags are not recommended because they rapidly breakdown.
Aluminum Oxide, Silicon Carbide, and Garnet: Aggressive media such as these may
be used but consideration should be given to accelerated wear on any part of the cabinet,
reclaimer, nozzle and hoses which comes in contact with the media.
In case of using of an aggressive blast media a tungsten carbide nozzle have to be used.
Service life of the tungsten carbide nozzle lasts 10 to 20 times longer than ceramic.
Glass Beads: Most beads have been treated to ensure free-flow operation even under
moderately high humidity conditions. Glass beads subjected to excessive moisture may be
reused after thorough drying and breaking up of any lumps.
3.5. Compressed air quality
Condensed water from the compressed air is reduced by the air filter at the air inlet
connection. Use of the air filter is of particular importance in areas of high humidity or when fine-
mesh media are being used. Dampness can cause media to clot, restricting free flow through
the feed assembly. An air dryer may be necessary if moisture problems continue.
3.6. Compressed Air Requirements
The required air compressor capacity is determined by the blast nozzle size and pressure.
