The spinner hanger style of wheel-blast equipment holds a rack of parts from the top and rotates them in front of the blast pattern, and these units can achieve 100% coverage. Units are of many sizes and can blast while the other rack is being loaded or unloaded.
In order to blast steel plates, I beams, or other long parts, the monorail is the return on investment winner. These units provide the most effective method for cleaning a wide variety of parts with variable speeds.
Perhaps the most common style of blast-wheel equipment, tumble blasters can handle high volumes of smaller parts that slowly tumble on each other. This is well suited for forgings, fabrications, and heat-treated parts.
These provide the most flexible and economical alternatives. Basically, these are large tables (with many diameters offered) that rotate under the blast. These units can hold a single larger part on a rack or a variety of smaller parts.
