Protoblast’s unique Airstream Abrasive Classifier increases total blasting effectiveness and efficiency

How it works

A bucket elevator provides a constant flow of used abrasive into the Airstream Chamber.

The Protoblast Airstream Abrasive Classifier passes a stream of air through a falling curtain of used abrasive to very effectively separate dust and fines from abrasive particles.

The speed and volume of the air stream is adjusted to match the type and flow of used abrasive.

Dust particles are carried through to the dust collector.

The abrasive scale and rust is collected in the waste chamber.

The heavier clean abrasive particles are then recycled into the feed hopper above the blast pot.


Benefits of the Airstream Abrasive Classifier
