Abstract
The treatment of hard surfaces by impacts of fine hard granules continually bombarded against them, as for peening, brightening, texturizing, compacting, reforming and/or cleaning adhesions from plates and other articles of steel, aluminum, or hard plastics, is accomplished with extraordinary effectiveness, yet with minimal loss of the blasting material due to breakdown, by providing and utilizing for the treatments selectively sized fractions, having for example 60-100 mesh, 100-200 mesh and 200-325 mesh grain sizes, of the rounded oblong grains, having a specific gravity of about 4.7, of a mass of refined zircon sand.
Claims5
In the process of treating hard surfaces by impact which comprises continually bombarding them with selectively sized fine hard granules hurled against them at high velocity, the improvement wherein said granules are a selectively sized fraction of the grains of a mass of refined zircon sand, said grains having rounded oblong configurations and having a specific gravity of about 4.7 and their sizes being within the range of from -60 mesh to +325 mesh sieve sizes.
