There are many methods of removing casting shell, insulation and sand from casting products including impact, water-jetting, shake, shot blasting etc. Shot blasting is a surface treatment process using high velocity metal abrasives to impact the surface of metal products, which can obtain excellent cleaning and surface preparation.
Shot Blasting Machine for casting shell removal includes shot blasting chamber, blast wheel (high velocity type), work-piece lifting system, screw conveyor, bucket elevator, magnetic separator, air wash separator, dust collector, Raymond mill breaker, vibrating Screen Separator & electrical control system.
Shot Blasting Used for Casting Shell Removal in investment casting, precision casting, sand casting, lost wax casting, lost foam casting
● Remove Sand from Casting
● Remove Casting Shell & Insulation from casting
● Prepare Surface for coating, cutting, maching etc
In general, shot blasting concentrates metal abrasive at high speed (80~110m/s) at the surface of casting thereby remove casting shell due to the metal abrasives strong impact.
