1Product Detail
We manufacture various sizes and compositions of walnut shell media in our production facilities. This ensures that the right media is available for each application. Special customer-specific solutions can also be produced. Our test labs and media production facilities work together to develop media that meets special requirements. All consumables including ceramic media, plastic media, polishing compounds, and auxiliary abrasives are manufactured to the highest quality standards.
Our product range of media and compounds is by far one of the most comprehensive in the world due to our 30 years of constant product development and improvement. There are more than 2,000 different kinds of polishing media, grinding compounds, and abrasives in our product range. We keep providing our worldwide customers surface finishing solutions and possibilities for different kinds of applications.
Walnut shell abrasive media represents an environmentally-friendly, biodegradable natural finishing solution ideal for soft polishing, cleaning, and surface preparation applications across diverse manufacturing industries. Manufactured from crushed and graded black walnut shells, this organic media provides gentle yet effective surface treatment without damaging substrate materials, making it perfect for delicate components, soft metals, plastics, and finished surfaces requiring non-aggressive cleaning or polishing action.
Our walnut shell media is precision-graded into multiple mesh sizes ranging from coarse (#8-12 mesh) for aggressive cleaning applications to fine (#60-80 mesh) for delicate polishing operations, ensuring optimal performance matching specific process requirements. This natural abrasive exhibits excellent absorbent properties making it ideal for oil removal, degreasing operations, and cleaning applications where residual contamination must be eliminated from part surfaces.
Environmentally-friendly organic abrasive made from renewable agricultural byproducts. 100% biodegradable and compostable, meeting strict environmental regulations and sustainability requirements for green manufacturing operations.
Soft polishing characteristics prevent substrate damage, scratching, or dimensional changes. Ideal for delicate components, soft aluminum alloys, brass, copper, zinc die-castings, plastic parts, and pre-finished surfaces requiring gentle cleaning without material removal.
Excellent oil and grease absorption capabilities make walnut shell media ideal for degreasing operations, cleaning machined parts with cutting oil residues, and absorbing liquid contaminants during dry tumbling processes without requiring additional cleaning compounds.
Available in comprehensive mesh size range from #8 (coarse) through #80 (fine) enabling precise application matching. Common grades include #12, #16, #24, #32, #36 mesh sizes serving diverse finishing requirements from heavy cleaning to fine polishing operations.
Economical consumable costs compared to synthetic abrasives provide lower per-part processing expenses. Moderate service life (40-80 hours typical) balanced with low acquisition costs delivers excellent value proposition for high-volume production finishing operations.
Specifically engineered for dry tumbling operations in rotary barrels, vibratory equipment, and centrifugal finishing machines. Eliminates wastewater treatment requirements, reduces environmental compliance costs, and simplifies process management compared to wet finishing systems.

Natural biodegradable composition eliminates hazardous waste disposal requirements. No RCRA permitting needed. Safe landfill disposal or composting. Reduces environmental compliance costs and regulatory burden compared to synthetic abrasives requiring special waste handling.
Soft organic material prevents surface damage, scratching, or dimensional changes on delicate components. Ideal for soft metals (aluminum, brass, copper), zinc alloys, plastic parts, and pre-finished surfaces requiring gentle cleaning without aggressive material removal or surface alteration.
Excellent absorbent properties enable effective degreasing and oil removal from machined parts. Absorbs cutting oils, hydraulic fluids, and liquid contaminants during processing. Reduces or eliminates need for additional cleaning compounds, simplifying process chemistry and reducing consumable costs.
Low dust generation during tumbling operations improves workplace air quality and reduces respiratory hazards. Minimal airborne particulates compared to some synthetic media. Safer working environment with reduced dust collection requirements and improved operator comfort during production operations.
Dry processing eliminates wastewater generation, treatment costs, and discharge permitting requirements. No pH adjustment, clarification, or filtration needed. Significant operating cost savings and environmental compliance simplification compared to wet finishing systems requiring water treatment infrastructure.
Lower acquisition costs compared to ceramic or synthetic media provide attractive per-pound pricing. Moderate service life balanced with economical replacement costs delivers excellent total cost of ownership for applications where gentle cleaning or soft polishing action is required without demanding extended media longevity.
