The Blasting Process
The basic blasting process has been around for over 100 years and Blastrac was the inventor of the first mobile shot blasting process in the early 80’s. Blastrac are now the undisputed global leader in this field. The Blastrac system is a mechanical process which is designed to remove sur- face contaminants, surface imperfections and coatings. The process is fully controlled, safe and environmentally sound. It uses no water, no chemicals or solvents, emits no pollutants or dust to the atmosphere and the removed material can often be fully recycled.Steel shot is fed by gravity through a control valve into an impellor. The impellor turning at high speed throws the steel shot through an adjustable opening at high velocity and at a specific angle on to the surface over which the self propelled machine is travelling. The steel shot impacts the surface and bounces off, as it does so material from the surface whether this is contaminants, coatings or the surface material itself is abraded and loose material together with the shot is drawn up into the machine by the airflow created by the vacuum unit. |
