Usage

Designed for versatility, this walnut shell media excels in sandblasting, tumbling, and vibratory cleaning operations. In sandblasting, the 12‑20 grit size creates a controlled abrasive action that removes rust, paint, and surface contaminants without gouging delicate substrates. For tumbling applications, the rounded shells act as gentle yet effective media, polishing parts, deburring edges, and preparing surfaces for subsequent coating processes. In vibratory cleaning, the media’s low dust generation and high impact energy ensure thorough removal of grime, oil, and particulate residues, making it ideal for aerospace components, automotive parts, and precision tooling. The reusable nature of the shells reduces operational costs, as a single batch can be reclaimed and reused multiple times after proper cleaning. Users ranging from small workshop owners to large manufacturing facilities benefit from the consistent particle size distribution, which translates to predictable results and reduced cycle times.
