Pressure Blast Systems
Here’s how our pressure blast systems work:
In a pressure blast machine, the abrasive media is contained in a pressure vessel under pressure (at 40 to 100 psi) for use in the process. Once the valve is open to start blasting, the media moves from the pressure pot through the grit valve and then through the hose to start blasting under pressure using the gun or nozzle. The media has two-to-three-times times the velocity on impact and would be close to three-times faster with stripping applications. Normal blasting pressure ranges from 35 to 45 psi.
Smaller and more compact pressure blast systems are available for applications where utilization and overall cost are a major deciding factor.
Parts tumbling baskets can be of great assistance when running many smaller-sized parts. It is harder to hold smaller parts while conducting blasting.
Portable vacuum-blast units and blast rooms incorporate “direct pressure” blast systems to enhance the impact and the speed of the work being done. Each of these direct pressure blast systems has direct blast guns attached to the pressure pot.
When using a blast gun manifold with multiple guns running at the same time, a suction unit is recommended because it is able to run continuously. Pressure units need to stop every so often to recharge the pressure vessel.
