    Walnut Shell Grinder are excellent soft grit abrasives used in blast cleaning and tumbling. Walnut shell grit is used in applications that require aggressive stripping or cleaning without damage or effect on the underlying subtrate. Organic and biodegradable, walnut shell is extremely durable, angular in shape but considered a soft abrasive.Also used in the oil industry as lost circulation material and as a filter media for cleaning produced water. Available in extra course to extra fine.

    Walnut Shell Abrasive – Natural, Tough & Eco-Friendly Blasting Media
    Product Description
     
    Our Walnut Shell Abrasive (Walnut Shell Grit) is a naturally derived, biodegradable blasting medium made from carefully crushed and screened walnut shells. It offers an exceptional balance of hardness and softness—aggressive enough to remove coatings and contaminants, yet soft enough not to damage the underlying substrate. It is the preferred choice for surface preparation, cleaning, and polishing across automotive, aerospace, marine, and industrial applications.
     
    Key Features & Benefits
     
    Non-Abrasive to Substrates: Cleans effectively without etching, pitting, or dimensional change to delicate surfaces (aluminum, fiberglass, alloys, plastics, and soft metals).
     
    High Durability & Low Dust: Dense particle structure provides multiple re-use cycles in blast cabinets, reducing media consumption and airborne dust.
     
    100% Organic & Biodegradable: Contains no free silica, heavy metals, or chemical additives. Safe for operators and environmentally responsible disposal.
     
    Excellent Deburring & Deflashing: Removes sharp edges and mold flash from plastic, rubber, and electronic components without surface stress.
     
    Uniform Particle Distribution: Consistent sizing (available in standard grit ranges) ensures predictable surface profiles and reliable finishing results.
     
    Common Applications
     
     
     
    Industry Typical Use
    Automotive & Aviation Cleaning engine components, turbine blades, aluminum wheels, and carbon removal without affecting tolerances.
    Marine & Yacht Maintenance Stripping anti-fouling paint from fiberglass hulls without gel coat damage.
    Electronics & Plastics Deflashing circuit boards, connectors, and molded plastic parts.
    Industrial Maintenance Removing light rust, scale, and grease from molds, dies, and precision tools.
    Stone & Monument Cleaning Gentle removal of graffiti and soot from historic masonry and soft stone.
    Available Grades & Packaging
     
    We offer a comprehensive range of grit sizes to match specific equipment and surface finish requirements:
     
    Coarse Grit (e.g., 6/10, 8/12, 12/20): Fast stripping of heavy coatings and paint.
     
    Medium Grit (e.g., 20/30, 20/40): General purpose cleaning and moderate deburring.
     
    Fine/Polish Grit (e.g., 40/60, 60/100, 80/200): Light cleaning, final polish, and delicate deflashing.
     
    Packaging: 50 lb (22.7 kg) heavy-duty poly bags, 2000 lb (907 kg) bulk super sacks, or custom packaging per customer request.
     
    Technical Specifications (Typical Values)
     
    Composition: 100% Crushed Walnut Shell
     
    Hardness: 2.5 – 3.5 MOHS
     
    Specific Gravity: 1.2 – 1.4 g/cc
     
    Bulk Density: Approx. 45 – 55 lbs/ft³ (720 – 880 kg/m³)
     
    Free Silica Content: < 1%
     
    Why Choose Our Walnut Shell Abrasive?
    Unlike synthetic plastic media that can melt or warp under heat, or mineral abrasives that can fracture substrates, walnut shell grit maintains its structural integrity and provides a cool, clean, and non-corrosive finish. It is the industry standard for "Clean and Inspect" operations.

    Application

    Walnut shell is a granular material and polishing abrasive that has been processed through crushing, screening, and other processes, with multiple micropores on the surface and good adsorption effect.

     

    Walnut shell filter material has high hardness, wear resistance, good compression resistance, and a pressure resistance of 23.4KgF. It has stable chemical properties, does not dissolve in acids and alkalis, strong adsorption and interception ability, and an adsorption rate of 27-50%. It has good hydrophilicity and resistance to oil immersion, with a specific gravity of g/cm31.25, slightly higher than water. The filling specific gravity is 0.85g/cm3, which is easy to backwash and regenerate. Compared with other filter materials, its advantages are that it directly uses backwashing before filtering, has low operating costs, and low backwashing strength, (6.71/S. m2), fast filtration rate (24-26/n), good effect. The treatment effect of oily water in oil fields is significant, with oil removal reaching 95% and oil content dropping below 5mg/l.

     

    Walnut shell abrasive is a natural polishing material that does not damage the surface of the workpiece and has a good polishing effect. It has excellent wear resistance, uniform particle size, and high shell content. The walnut shell polishing material is mainly used for polishing and deburring in industries such as eyewear accessories, pearl jewelry, buttons, electronic components, stamping parts, etc. Walnut shell particles with strong compressive strength and particle size ranging from 1.25 to 1.60mm have an average compressive limit of 0.2295KN (23.40kgf). Walnut shell particles with a particle size of 0.80-1.00mm have an average compressive limit of 0.165KN (16.84kgf).

     

    Product Usage:

    1. Oilfield oily wastewater treatment: degreasing and suspended solids.

    2. Industrial oily industrial water treatment: degreasing and suspended solids.

    3. Civil and industrial water treatment: Remove suspended solids in water and improve water quality.

    4. Car seat cushion filling.

    5. Abrasive polishing (pearl jewelry, glasses accessories, buttons, electronic parts, stamping parts, hardware tools)

    6. Fruit shell powder (soap solution, hand sanitizer) filling, etc.
