Offering both manual and semi-automatic modes of operation, the Model SS-10 SA rotary table wet blast system from Guyson uses abrasive or bead-type media for dustless blast cleaning, descaling, surface preparation and cosmetic finishing of components that may be too damp or oily for dry-blast processing.

The 60" × 70" blast cabinet stands 96" tall and is fabricated from non-corroding composite material. The interior of the wet blasting chamber is lined with sheet rubber for abrasion resistance. A 50" × 50" swing door provides access to the blast enclosure on each side. On the right side, a track extension and transfer cart allows the 49"-diameter rotary table to be rolled out for loading and unloading. A drip tray beneath the track extension is standard.

The system features five wet blast guns. For use in manual mode, the pistol-grip gun can be hand-held or clamped in the gun bracket to allow the operator to use both gloved hands for component manipulation. Four wet-blast guns are mounted on a horizontal oscillator for use in semi-automatic operation.

A mixture of water and media is delivered to the guns from a 50-gallon slurry hopper at the bottom of the blast cabinet by a seal-less, bearing-less centrifugal pump with a polyurethane impellor and cast urethane lining. The slurry pump is powered by a two-speed motor, so the operator can choose a higher or lower slurry volume depending on the components and the wet blasting process requirements. Compressed air at regulated pressure is injected into the wet blast guns to disperse the liquid and accelerate the media particles, both of which affect the aggressiveness of the wet blasting process and the speed of the work.
