Wheel blast equipment propels metallic media through centrifugal wheels onto the parts for processing. The velocity, size, shape, and density of the metallic media provides cleaning, peening, profiling ,and surface preparation finishes.
There are a number of wheel blast equipment designs to choose from. The size and weight of parts will determine which wheel blast machine is best suited for the application.
Tumble wheel blasters are designed for processing batches or small to medium parts. The belt rotates and tumbles the parts as the wheel throws the media, providing automated finishing. The tumble action achieves full coverage in minimal time cycles.
Spinner hanger wheel blast machines are designed for small to medium parts that may be fragile or awkward for tumble or blast finishing. These parts are placed individually on fixtures to prevent any part-on-part contact. The fixture rotates as two wheels propel the abrasive, offering 360-degree coverage.
Single chamber spinner hanger can be used for processing larger parts to achieve full coverage without having to flip or rotate the part. Capacity for spinner hangers is up to 2000 pounds.
Dual chamber spinner hanger wheel machines offer a more productive option for batch processing. The dual chamber allows the operator to unload finished parts and load raw parts in one chamber, while the other chamber is full of parts being finished. When the blast cycle is completed, the chamber rotates as the process repeats.
Table wheel blast equipment provides options to finish large parts weighing up to 10,000 pounds. The rotating table helps expose the parts to the media stream. Table diameters range from 36" to 96". Table blast machines, depending on the diameter, will come with one to three wheels to provide coverage on the exposed surface. If full coverage is needed on the parts, they will need to be flipped over. Crane slots are available as an option to help facilitate safe loading and unloading.
Pass through belt blast machines offer continuous processing. The wire mesh will feed the parts though the wheel blast stream for cleaning or finishing. This allows for long parts, that cannot be finished in any other wheel equipment, to be processed. It also allows for smaller parts to be finished without opening or closing doors. This can be manually operated or set up as part of a robotic cell. There are a number of options with belt widths, chamber heights, and number of wheels to provide consistent finishes.
