Starblast™ Guidelines
easily achievable using Starblast™. Operators can simply
accomplish this by working faster or using a greater“nozzle-to-work” distance.
Starblast™ often is chosen to clean vital equipment suchas pipe used in hydraulic applications. Here, the roundedgrains of the product eliminate costly problems caused byabrasive embedding in metal and eventually coming loose.
Starblast™ XL is used for applications requiring abrasives
containing less than 1% free silica.
How to Use Starblast™ Effectively

Where to Use Starblast™
Starblast™ is a unique mineral abrasive that is especiallyvaluable in industries where blasting applications arecommon. Users of Starblast™ in the steel fabricating
industry, for example, find it very effective in removing millscale and rust from steel. Paints of all types are removed
effectively by Starblast™. Power companies use Starblast™
for maintenance work where critical equipment, suchas electric motors, cannot tolerate exposure to large
volumes of dust.
Regardless of the industry, operators of blasting
equipment prefer Starblast™. They find that Starblast™
offers excellent accuracy in cutting and confined spot
preparation. Also, the precise control and manageability
enables them to do an excellent job at feathering edges.
White metal finishes, which are difficult to achieve withmany abrasives, are readily available with Starblast™.
Near white, commercial or brush-off finishes are also

Starblast™ works in all air-blast equipment designed
for loose abrasives at a much leaner abrasive/air ratio.
Adjusting the correct amount of feed is done by starting
the blast operation with the abrasive feed valve in theclosed position. Slowly open the feed valve until theabrasive stream is just visible. At this point, slowly close
the feed valve until the abrasive stream can no longer beseen. (Generally, it is better to feed too little Starblast™
than too much.) With this proper abrasive/air mixture,
blasting can now begin. (Table 1 shows the relationship of
air volume to nozzle diameter.)Starblast™ can make a good blasting operation evenbetter. It cannot, however, produce maximum value if poor
blasting practices are used, such as low air pressure,incorrectly sized or worn nozzles, or improper abrasive
feed rates. The correct abrasive/air mixture is important,especially when using Starblast™. Slight movement of
the feed valve can cause large changes in abrasive
consumption. Table 2 shows recommended Starblast™
flow rates at various nozzle pressures.

• To protect the compressor, allow intermittent operation by using only 70–80% of its rated output.
• Pressure drops as hose length increases, and more volume is needed to run a given nozzle at a desired pressure. Use hypodermic gauges to find nozzle pressures.
