Crushed Walnut Shell Blasting & Tumbling Media
Manufactured from dried, crushed, and air-classified English walnut shells (Juglans regia). Provides an angular yet non-destructive soft blasting and tumbling medium (Mohs 3.5) that removes paint, carbon deposits, and mold flash without etching aluminum, brass, or composite substrates.
Direct Gongyi Plant Processing & Sizing Precision
Every batch of Crushed Walnut Shell Blasting & Tumbling Media is refined, crushed, magnetically separated, and precision-screened in our 35,000 m² Gongyi facility—eliminating middleman quality variation and ensuring strict adherence to international industrial standards.
Strict Raw Material Selection & Thermal Processing
Processed from selected high-grade raw ore under tightly monitored kiln/furnace temperature profiles to guarantee consistent chemical purity, specific gravity, and mechanical durability across every 20' FCL load.
Narrow Particle Size Distribution & Zero Oversize Contamination
High-frequency vibrating screens and air classification lines remove dust and oversize particles, ensuring uniform packing density and predictable industrial performance.
In-House XRF Assay & Signed COA with Every Shipment
Tested in our ISO 9001:2015 metrology lab for chemical composition, moisture, bulk density, and sieve retention prior to container sealing.
Chemical & Grading Technical Datasheet
Tested in our Gongyi plant laboratory prior to shipment. Every export container includes a batch-specific Certificate of Analysis (COA).

Primary Industrial Sectors & Use Cases
Engineered for reliable performance across heavy industrial manufacturing, surface preparation, and thermal processing.
Aerospace & Automotive Engine Cleaning
Removes carbon deposits from turbochargers, intake valves (BMW/VW walnut blasting), and aircraft turbine blades without dimensional loss.
Plastic, Rubber & Die-Cast Deflashing
Strips mold flash from electronic connectors, rubber O-rings, and aluminum die castings.
Vitrified Grinding Wheel Pore Former
Fine walnut shell flour burns out cleanly in kiln firing to create controlled induced porosity in vitrified wheels.
Jewelry & Metal Vibratory Polishing
Impregnated with rouge or polishing paste for mirror-finishing brass, copper, silver, and eyewear frames.
