Walnut Shell 70 mesh

Why Choose Walnut Shell 70 Mesh for Your Blasting Process

Selecting the correct abrasive is a balance between cleaning speed and surface preservation. Walnut shell 70 mesh sits at the gentlest end of the blasting spectrum. Its angular particle shape provides effective scrubbing action, while its low Mohs hardness (typically 3.0–4.0) ensures it fractures upon impact with harder substrates, absorbing energy and preventing surface damage. This makes it uniquely suited for applications where glass bead is too aggressive and plastic media is too slow.

Typical Industrial Applications

• Mold and die cleaning: Removes release agents, plastic residue, and light oxidation from injection molds and rubber molds without altering critical tolerances or polished surfaces.
• Engine component refurbishment: Safely strips carbon deposits from pistons, valves, cylinder heads, and intake manifolds without affecting base metal dimensions.
• Electronics and electrical cleaning: Gently cleans delicate connectors, insulators, and circuit board tooling without conductive residue or surface abrasion.
• Deburring and deflashing: Removes fine burrs and flash from machined plastic, aluminum, and brass components without rolling over edges or creating secondary finishing work.
• Heritage and restoration work: Cleans historical artifacts, stonework, and architectural metalwork where substrate preservation is paramount.

Process Compatibility and Usage

Walnut shell 70 mesh is suitable for suction-fed and direct-pressure dry blasting systems. It can also be used in wheel-blast equipment where low-impact cleaning is required. For optimal results, maintain blast pressure between 2–4 bar (30–60 PSI) and adjust nozzle distance based on substrate sensitivity. The media is friable and will break down over multiple cycles; typical reusability ranges from 4–8 cycles depending on application intensity. Dust extraction is recommended to remove fractured shell particles and maintain consistent cutting performance.

Pack Options and Logistics

We supply walnut shell 70 mesh in 25 kg bags, 50 kg bags, 1-ton jumbo bags, bulk totes, and drum packs. This range supports both small-scale trial orders and full production-volume deliveries. Material is sourced and graded for consistent particle distribution, minimizing fines and oversize that can cause inconsistent finishes or nozzle clogging.
