Walnut Shell 60/80 mesh

Understanding Walnut Shell 60/80 Mesh Abrasive

Derived from crushed walnut shells, this organic media is characterized by its angular shape and moderate hardness. The 60/80 mesh size offers a balanced particle distribution, making it aggressive enough to clean surfaces efficiently while being soft enough to protect sensitive substrates like aluminum, brass, fiberglass, and plastics. Unlike harder mineral or metallic abrasives, walnut shell media is non-toxic, biodegradable, and dust-free when properly handled, contributing to a safer and more environmentally friendly blasting operation.

Key Applications for Walnut Shell Blasting

This versatile media is specified across a range of precision cleaning tasks. Its primary advantage is the ability to preserve the integrity of the original surface profile.

• Automotive and Aerospace Restoration: Ideal for stripping paint, carbon, and varnish from engine components, pistons, valves, and turbine blades without causing dimensional changes or surface stress.
• Mold and Die Cleaning: Effectively removes residues, release agents, and light oxidation from injection molds, rubber molds, and die-casting tools, extending tool life and reducing downtime.
• Electronics and Delicate Metal Finishing: Used for deburring small, intricate parts, cleaning electrical contacts, and preparing surfaces for bonding or coating without the risk of short-circuiting or damage.
• Fiberglass and Composite Surface Prep: Safely removes gel coat, paint, and marine growth from boat hulls and composite structures without damaging the underlying fiberglass matrix.

Operational and Handling Tips

To maximize the performance and lifespan of Walnut Shell 60/80 mesh, consider the following best practices:

• Blast Pressure: Operate at lower pressures, typically between 2-4 bar (30-60 PSI), to prevent excessive media breakdown and maintain the delicate cleaning action.
• Nozzle Selection: Use a venturi nozzle with a larger orifice to reduce particle velocity and impact stress on the substrate.
• Recycling: Walnut shell media can be recycled multiple times. Its longevity depends on blast pressure and the hardness of the contaminant being removed. Implement a proper screening process to remove fines and contaminants between cycles.
• Storage: Store in a cool, dry place away from moisture to prevent clumping and degradation. Sealed bags or containers are recommended.
