CRUSHED WALNUT SHELLS AUSTRALIA

what are crushed GROUND walnut shells used for?

Crushed Walnut Shells are used for a variety of purposes:

When used as a blasting media, walnut shell grit is extremely durable yet it is a soft abrasive for blasting soft or delicate material, and is extremely effective in removing paint, dirt, grease scale, carbon etc. It remains unchanged and is re-usable when reclaimed in sandblast cabinets.

Craft Pin Cushions: Fill Pin Cushions with Coarse or Medium Grade. It keeps pins sharp.
Sand Blasting Media:

- Fine Crushed Walnut Shells are used to clean and not damage or dent aluminium, brass, and

sheet metals, the low heat prevents warping of materials. Also used to clean rust, grease,

carbon, or scale on car parts like Carburetors , Intake Manifolds, Turbo Chargers, and Exhausts.

Audi, Porsche and BMW do this as part of a Major Service.

- Fine grade can take off single layers of paint or Graffiti, while leaving undercoat or wood

panels undamaged. Does not etch wood or pit metal.

- Use to safely blast soft or thin metals, bricks, or wood at 120psi.

- Coarse Grade is used by Ships to clear out scale from huge Diesel Turbo Chargers & Exhausts.

Tumbler Medium: polishing brass bullet casings for reloading shells. Tumbler Media.
Polishing and Tumbling: Brass, Rocks & Stones.
Anti-Slip applications: add to paint or epoxy for stairs, decks, pools, floors, ramps.

- Mix with Sawdust in a Smoker Box, to help the sawdust smoldering process by adding larger particles for better air flow through the sawdust.
- Use in The Smoking Gun electric smoke infuser in Restaurants.
CREATE BRAILLE SIGNS: Place Med Grade on glued surfaces in text formation.

Technical info:

Crushed Walnut Shells have a hardness of 3.5 MOH and 91 Rockwell, and a specific gravity of 1.2-1.4 Crushed Walnut shells perform well in a variety of pH and temperature conditions and are resistant to mould & fermentation.

THE HISTORY OF SANDBLASTING WITH CRUSHED WALNUT SHELLS:

In the 1960’s the U.S. Navy pioneered a new method of removing paint from Navy submarines using FINE and MEDIUM CRUSHED WALNUT SHELLS.

The Navy had been refurbishing ship hulls by sandblasting them with abrasive mineral grit that removed all of the layers of paint and coatings down to bare steel, which proved costly to repaint.

They found that FINE Walnut Shells removed the top coating of paint or Graffiti, while leaving the valuable undercoating intact. The coarser MEDIUM Grade was used to take multiple top layers of paint off, while leaving undercoat intact. This innovation offered the Navy significant savings in time and money, and helped pioneer environmentally-friendly paint removal.
