Product Description

1-2mm Grit blasting crushed walnut shell

<sup>Walnut Shell Grinder for Polishing:
Walnut Shell Grinder are used in many polishing and/or deburring applications. Walnut shell media is used for polishing or cleaning fine metals, alloys, mechanical parts, shell cartridges, eye glass lens, rocks, stones, coral, ivory, beans, and seeds.
Jewelers use walnut shell media treated with rouge in both tumbling and vibratory applications for polishing gems and fine jewelry.
When polishing the media size should be small enough to freely pass through openings or large enough to avoid lodging in openings or crevices.

Walnut Shell Grinder for abrasive blasting:
Walnut Shell Grinder are a type of abrasive blast media used for cleaning. Typical substrates are metals, fiberglass, woods, plastics and stone. The walnut shells are ground to various sizes from coarse to extra fine depending on the application. The walnut shells are used in the same manner as typical blast media. Walnut shells are durable and can be re-used in many applications. Walnut shells can remove matter from surfaces without scratching or pitting underlying material.
Walnut shell is biodegradable, non-toxic, environmentally safe and cost effective for blasting. Walnut shell does not cause silicosis.</sup>
