Walnut Shell

Walnut shell grit is the hard fibrous product made from crushed walnut. When used as an abrasive, walnut shell blasting media is extremely durable, angular and multi-faceted, yet is considered 'soft abrasive'. Walnut shells are ground into various grit sizes to be used for blast cleaning and polishing. Size of grit needed is generally determined by the weight and character of the parts to be processed. Consider the size of perforations or holes through which the walnut shells must pass when screen separating parts from media after use.

Walnut shell blasting media is ideal for general purpose deflashing of plastic parts and for tumble polishing of metals such as aluminum, bronze and brass. Cleaning by soft grit blasting is particularly effective where the surface of the substrate under its coat of paint, dirt, grease, scale, carbon, etc. Should remain unchanged or otherwise unimpaired. Walnut shell grit can be used as a soft aggregate in removing foreign matter or coatings from surfaces without etching, scratching or marring cleaned areas.

When used with the right walnut shell blasting equipment, common blast cleaning applications include stripping auto and truck panels, cleaning delicate molds, jewelry polishing, armatures and electric motors prior to rewinding, deflashing plastics and watch polishing.
