Wheel blast cleaning systems can provide cost effective and high quality surface preparation of steel with close adherence to process controls and rigorous maintenance to assure consistency and economy of production.
These blasting systems can be permanent fixtures or part of an automated system in a blast hall for the preparation of steel plates and sections before painting. Centrifugal blast cleaning systems also can be found in portable machines used in the field for the preparation of steel and concrete substrates for maintenance painting.
This article begins by looking at blast cleaning abrasives and their effect on cleaning, surface profile, and appearance. It also looks at the importance of selecting and maintaining an appropriate operating mix. Finally, it describes the operation of the sub systems of a centrifugal blast system with the most effect on the process and the control of product quality, including the blast wheel, the abrasive recycling system, and the dust collector.
