In the case of wheel blasting, a centrifugal force is used by a wheel to propel the abrasive media against the surface. Essentially, it’s called as an airless abrasive blast cleaning since there's no gas or liquid used to blast. The common recyclable abrasive materials used are the grit, pellets, cut wire, steel or stainless steel shot. The wheel blast machine employed is very high-powered and efficient. When it comes to the number of wheels and power used in an operation depends on the object to be blasted and the desired result.
Compared to air abrasive blast cleaning, a wheel blasting is considered to be more flexible for a wider array of parts, finish results and operation output. The wheel blast machines also come in wider design and capacity sizes both for high and low production parts needed. Small steel shot media provides a fine consistent finish, while other materials like steel grits, aluminium shots, even plastics and organics are also used.
Wheel abrasive blast cleaning machines are configured with the basic design criteria, including blast wheel/s, work handling system, abrasive reclaim system, abrasive storage system, electrical system, separation system and ventilation system. A correctly sized and configured wheel machine can propel greater volume of media which means shorter cycle times and so higher output.
