ABRASIVE OR RELATED BLASTING WITH PARTICULATE MATERIAL

**Definition:** This place covers:

Abrasive or related blasting with particulate material, whereby a blast of any particles or pellets dispersed in air, gas, or liquid ( or an equivalent jet of particles or pellets projected or energised by other means ) is used for the treatment of surfaces or cutting of materials, the particles usually being of abrasive material.

Blasting with jets acting as abrasive jets, but not containing particulate material in the exceptional cases of deburring, removal of extended surface areas and jet milling of local recessions e.g. grooves.
