A practical, procurement-ready overview of using hazelnut shell powder (screened grit) as a bio-based abrasive — including recommended grit ranges, performance-critical quality markers (dust, hardness consistency, foreign matter control), and packaging approaches for industrial supply.
Hazelnut shells are a hard, lignocellulosic material that can be milled into granules and powders and then screened into defined grit bands. In abrasive applications, shell-based media are usually positioned as a soft-to-medium abrasive intended for cleaning, surface preparation, polishing, deburring, and gentle stripping where you want to reduce the risk of cutting into the base material.
The key procurement drivers for abrasive-grade shell powder are not “food” attributes like flavor or roast — they are particle size distribution, fines (dust) control, foreign matter limits, and repeatable flow and density for consistent metering through blasting or finishing equipment. Well-controlled lots help operators maintain stable performance (finish quality, cycle time, and dust management) and reduce unplanned shutdowns.
Typical use cases include:
Performance depends on your equipment (nozzle, cabinet dust extraction, wheel blast, vibratory bowl), substrate, and target finish. Most programs start with one or two grit bands and adjust after a controlled trial.
Typical starting points for pilots and scale-up. We align grit band, fines level and packaging to your equipment and finish target.
If you share your process (blasting vs. vibratory), nozzle/wheel details, and target surface result, we can recommend a practical starting grit band.
The variables that most often drive performance, consistency, and operator experience in abrasive applications.
Shell-based abrasives are often selected to be gentler than mineral abrasives. The right grit choice helps you balance cleaning speed with surface protection.
Abrasive media logistics focus on keeping product dry, clean, and consistent while minimizing dust during handling.
For dust-sensitive sites, dedusted grades and careful pallet wrapping reduce handling losses and improve operator experience.

| Parameter | How we align it |
|---|---|
| Grit / mesh band | Defined sieve fraction with agreed tolerance; screening approach aligned to your equipment |
| Fines content (dust) | Dedusting / secondary screening to limit excessive fines and reduce start-up dust spikes |
| Moisture | Controlled to support stable flow and minimize clumping during storage and transport |
| Bulk density | Measured to support consumption planning and consistent metering/feeding behavior |
| Foreign matter | Sorting and controls to limit stones, metal fragments, and oversize particles |
| Oversize/undersize limits | Acceptance thresholds defined to protect nozzle flow and maintain finish consistency |
| Ash/mineral content (optional) | Specified when low mineral content is important for wear reduction or downstream cleanliness |
| Odor / color consistency (optional) | Aligned where visual or residue considerations matter (process-dependent) |
| Packaging | Lined sacks or FIBC; palletized and sealed to reduce moisture pickup and contamination risk |
| Documentation | COA, packing list, origin documents, and lot identification per shipment |
Final values depend on your application (blasting vs. finishing), dust extraction capacity, and the surface result you’re targeting. For many programs, the most “make-or-break” markers are grit band + fines limit + foreign matter control.
A short, structured trial plan helps you select a grit band quickly and lock a repeatable specification for ongoing supply. Below is a practical workflow used by many procurement and operations teams.
Share your substrate (metal/plastic/composites), coating type (if any), and target result, and we can propose a practical starting band and trial checklist.
Most customers start with screened hazelnut shell grit (a defined mesh band) rather than an unscreened powder. Screened media provides more predictable feeding, cut rate, and finish. Fine powder grades are usually reserved for gentler finishing or blends.
Yes. We can supply calibrated size fractions and manage fines through screening and dedusting. If you share your equipment type and dust constraints, we can recommend a starting band and align tolerance to your process.
The fastest way is to share: (1) application type (blasting/tumbling/polishing), (2) target grit/mesh (or nozzle size and finish goal), (3) monthly/annual quantity, (4) destination country, and (5) packaging preference (25 kg sacks or big bags).
We typically ship in lined sacks or FIBC big bags, palletized for sea/road/air freight. Packaging is selected to reduce moisture pickup, maintain sieve integrity, and minimize dust release during handling.
Yes. We structure annual and multi-shipment programs with consistent specifications, lot traceability, and forecast-based planning to keep media performance stable across replenishment cycles.
Send your application details (equipment type, target grit/mesh or nozzle size, quantity and destination). We will propose suitable grit bands, packaging, and a shipment plan for trials or steady supply.
