SPT Automatic Shot Blasting Machines

SPT manufactures Automatic Shot Blasting Machines for plain steel sections, fabricated steel items, plates
and pipes. These can also be supplied with a
SPT Automatic Painting System and  Drying Oven to provide a
blasting and painting system or preservation line.

All our Shot Blasting Machines are of the airless centrifugal type were a motor fitted with a blast wheel is used to
throw the abrasize. The blast cabinets are lined with 10mm thick rolled manganese steel plate on all surfaces and
as standard we fit 12mm thick "Inline" liners directly in front of all the blast wheels for additional protection.

To keep the abrasive in first class condition we fit extra length Airwash units to all machines, this ensures that all
"fines" and other contaminents are removed from the abrasive stream to keep the blasting efficiency at its highest.

cost and best quality for your surface preparation needs.
