Frequently Asked Questions
What is crushed walnut shell used for?
Crushed walnut shell (CAS 84012-43-1) is graded granular media from the hard shells of Juglans walnut. As a tough yet relatively soft, biodegradable abrasive it is used as blasting and tumbling media for deflashing, deburring, and finishing, and as a filtration medium, filler/extender, anti-slip additive, and cosmetic exfoliant.
Why use walnut shell for blasting instead of harder media?
Walnut shell is a soft-blast abrasive that removes flash, burrs, coatings, and contaminants without aggressively cutting the underlying substrate. That makes it suited to deflashing, deburring, and cleaning where harder media like sand or grit would erode the part.
What grit sizes are available?
Crushed walnut shell is screened into multiple grit/mesh grades for different blasting, tumbling, and filtration duties, from coarse deflashing grades to fine finishing and exfoliant grades. The exact size distribution per lot is confirmed on the Certificate of Analysis; request the CoA for the grade you need.
Is crushed walnut shell biodegradable?
Yes, it is a biodegradable vegetable-derived abrasive, classified under HS 1404.90 (vegetable products n.e.s.). This is part of why it is selected as a media in water/produced-water filtration and as a natural exfoliant.
How is bulk crushed walnut shell packaged and priced?
It ships in bags, supersacks, and bulk for industrial finishing, filtration, and formulation buyers. Packaging, MOQ, and pricing depend on grit grade and volume; submit a bulk RFQ with your target mesh size and quantity.
