Wheel Elements:

Hot Spot:

Power Requirement of Wheel and Air systems

For abrasive flow of 2100 Lbs per minute

• 21 operators
• ½” nozzles
• Compressed air consumption 350ft³/min

per nozzle

• Compressor power 1400 kW

OR

4 wheels 20 HP each

80 HP (60 KW)

Energy factor 24 !!!

Advantages:

•    Velocity of shot easily controlled through wheel speed.

•    High flow rate of abrasive will provide high production.

•    Economical – one wheel can throw 300 lbs per minute with a 15 HP

wheel equal to five 3/8” nozzles at direct pressure at 80 psi at a

power requirement of 190 HP.

•    Self contained unit does not require a compressor.

Disadvantages:

•    Can only use metallic media.

•    Can damage delicate parts.

•    Not good for localized peening.
