Blasting & Surface Finishing
Natural Abrasive Supply for Blasting, Shipyards and Surface Finishing
What a blasting operator needs isn't a product family — it's cleaning a surface without damaging it, managing dust safely, and getting the same result batch after batch. This page lines up shell and granule against those three needs.

Quick answer
Blasting workshops, shipyards and surface-finishing plants buy two groups of product from us. Operations doing heavy stripping with their own grinding line take whole or cracked hard shell. Jobs that need calibre precision prefer shell granule that's already ground to a defined calibre. The common reason: shell-based abrasive contains no crystalline silica — the cause of silicosis — and cleans metal without deforming it. We supply domestically to workshops, shipyards and industrial plants by truck, and for export by 20ft or 40ft HQ container.
In this sector, abrasive choice starts with the surface, not the material name. Stripping thick coating off a ship's hull and removing oxide from an aluminum rim are not the same job and don't call for the same grain. Heavy stripping wants an aggressive, durable grain; delicate surfaces want a grain that breaks on impact and removes the dirt, not the metal. That's exactly why the shell family sits on one page: the hardness ranking runs from peach kernel down to sour cherry pit, and once you tell us the job, we suggest a place on that scale.
The second distinction comes from form. Operations with their own grinding line take whole or cracked shell as raw input and keep calibre control on their own line — that makes sense for high-volume, regular consumers. Workshops without such a line feed ready-made granule directly into the machine. Shell abrasive containing no crystalline silica — the cause of silicosis risk — is the main reason it's preferred over sand in this sector, but that doesn't mean dust-free work: organic dust is still dust, and workplace ventilation and respiratory protection are standard practice regardless. Its natural, biodegradable structure also gives an easier picture on the waste side compared with silica sand.
We are a supplier and exporter working close to the source. We take shell from the cracking and processing facilities where it separates, coordinate grinding and calibre selection to the intended use, and have packaging and paperwork prepared. We deliver domestically to blasting workshops, shipyards and surface-finishing plants by truck; for export we load by container on FOB/CIF terms. We don't publish a price list — we quote once surface, volume and delivery point are clear.
What matters in this job
The buyer’s priority is our starting point
Clean the surface, don't deform it
The line in this job isn't where cleaning stops — it's where the surface starts to be damaged. Steel grit and silica sand are fast on stubborn dirt but easily bury and warp aluminum, brass, composite and painted surfaces. A shell-based grain breaks on impact; the energy goes into the dirt, not the metal. In restoration and mold maintenance, that difference is what separates saving the job from scrapping the part.
No silica — but dust management is still required
Crystalline silica causes silicosis when inhaled; shell abrasives contain none, and that's the concrete reason this sector has moved away from sand. We say this as fact, not as a miracle claim: every blasting dust is a respiratory load. Cabin ventilation, dust collection and proper respiratory protection are standard practice when working with shell too. A supplier who isn't straight with you on this won't be straight with you on calibre either.
The result shouldn't change when the batch changes
The real cost in a workshop isn't the material itself — it's a job that's gone off-spec. If the result changes with pressure and distance held constant, the batch is usually the culprit: grain distribution has shifted, or dust content has risen. For high-volume work, sample approval isn't a formality with us — it's the reference for the batch to be shipped. Calibre is matched to request; shipment is sourced as close as possible to the approved sample.
Consumption, reclaim and waste
Organic abrasive works by breaking down; a portion turns to dust with each cycle. On lines with a reclaim system, the grain cycles several times and a fresh batch is needed as dust content rises — the calculation runs on cycle count, not a single-bag price. Its natural, biodegradable structure also makes disposal of used abrasive easier. Telling us up front whether your line has reclaim directly shapes which hardness we suggest.

Nut Shells & Biomass Fuel
7 products Hazelnut Shell
The easiest-to-find raw input in this sector: Black Sea sourcing keeps it abundant year-round, so it's the first stop for workshops with their own grinding line that want to keep calibre in-house. Sitting at medium hardness, it works safely in shipyard and soft-metal jobs.
Walnut Shell
The classic for heavy stripping: its dense structure compared with other shells removes rust and old paint layers without eroding the metal. It's also a recognized item in this sector as an abrasive fill for pipeline internal cleaning (pigging).
Apricot Kernel Shell
A medium-hard raw shell that cleans without scratching; sourced from Malatya, it can be drawn in volume and on a regular basis. Surface-finishing plants doing their own grinding choose it when they want a grain close to the delicate end and prefer to set calibre in-house.
Almond Shell
The light, fibrous end of the family — among the least aggressive of the hard shells. On delicate surfaces where scratching ends the job, it's the raw input workshops with their own grinding line look to when starting from the soft end.
Pistachio Shell
A medium-density raw shell used as a light-blasting input on jobs that fall between too aggressive and not quite delicate — a bridge item for work that sits between coarse and fine.
Peach Kernel Shell
One of the densest structures among hard shells — the raw input for heavy work in this sector. For workshops stripping stubborn rust and thick coating off ship hulls, industrial tanks and heavy equipment, it sits at the top of the hardness ranking.
Sour Cherry Pit
Its smooth, uniform size makes it work as a light abrasive that cleans delicate parts without scratching. A niche item on the blasting side — it comes up when the priority is not touching the surface, not aggressiveness.

Industrial Granules
7 products Walnut Shell Granule
The most versatile abrasive in this sector, available in defined calibre ranges: in mold maintenance it removes oil, soot and resin residue without scratching the surface; in automotive and boat restoration it strips rust underneath while protecting the paint layer above. The stock item for workshops that want one granule to cover more than one job type.
Apricot Shell Granule
Hard but friable — that structure is what makes it work here: the grain breaks apart on impact, so aluminum, brass and delicate alloys aren't deformed. Preferred for fine polishing and finishing where an aggressive grain would cost you the part.
Corn Cob Granule
It sits more on the cleaning side than the blasting side: low abrasiveness and high absorbency make it suited to pulling oil/moisture off metal parts, equipment and floors. For jobs where you want to collect dirt, not remove material from the surface.
Hazelnut Shell Granule
The workhorse: general-purpose blasting, surface roughening before paint or coating, machine-part cleaning. Its abundant year-round sourcing makes it the granule with the lowest supply-interruption risk for lines that consume regularly.
Pistachio Shell Granule
Being available in different hardness grades means control in this sector: it gives adjustment room where an aggressive grain is risky but the job still needs to move forward. For workshops doing controlled abrasion and final surface treatment.
Almond Shell Granule
The softest end of the granule side — notably lower hardness than walnut, hazelnut and peach kernel shell granules. Used in cleaning jobs on electronics, optics and fine surfaces where scratch risk is unacceptable.
Peach Kernel Shell Granule
The hardest of the shell granules: heavy blasting, thick coating removal and lapping/deburring on metal parts are its domain. In shipyard and casting/automotive plants, it's the top of the ranking when you want to do the toughest job with an organic abrasive.

Selection guide
Which one should you buy?
Tell us what you need; let's narrow it down together.
Tell us what we need-
Tell us the surface, not the mesh number
The most useful information when we take a request isn't a figure — it's a sentence: what material, what dirt, what pressure, and what surface result you're after. Those three answers narrow hardness and calibre on our side. If you already work to a mesh range, send it too, but it isn't enough on its own — the same mesh at different hardness gives a very different result.
-
Raw shell or ready-made granule?
If you have your own grinding line, taking whole or cracked shell as raw input and keeping calibre in-house gives you flexibility; high-volume, regular consumers usually take this route. Without such a line, ready-made granule feeds straight into the machine with no intermediate step. Telling us this up front gets the quote from the right line item.
-
Find your place on the hardness ranking
Heavy jobs (thick coating, stubborn rust, ship and tank surfaces) use peach kernel and walnut. Medium jobs (general blasting, surface prep) prefer hazelnut and pistachio. Delicate jobs (aluminum, brass, optics, electronics, scratch-sensitive surfaces) use almond, apricot kernel shell and sour cherry pit. If your job falls between two groups, we can send two samples together for high-volume requests.
-
Test on a hidden area before switching abrasives
When switching to a new abrasive, running the first application on a hidden test area heads off surprises you can't undo later — a grain that's right on paper can behave differently on your line. For serious-volume evaluations, a comparison via sample can also be arranged on request.
FAQ
Frequently asked about Blasting & shipyards
Do shell abrasives really contain no silica? Is a mask still needed?
Shell-based abrasives contain no crystalline silica — the cause of silicosis — and that is the concrete, verifiable reason this sector has moved away from silica sand. But that doesn't mean dust-free work: organic dust is still a respiratory load. Ventilation, dust collection and proper respiratory protection are standard practice when working with shell too. Removing the silica risk doesn't remove the need for safety measures.
Should I take whole shell or ready-made granule?
Your line decides. With your own grinding capacity, you can take whole or cracked shell as raw input and set calibre in-house — that gives flexibility to high-volume, regular consumers. Without a grinding line, ready-made granule feeds straight into the machine. The two can also be combined in one shipment.
Is it used in shipyards and on ship hulls?
Yes, the heavy-end items are chosen for this job: peach kernel and walnut-based abrasives stand out for thick coating removal and stubborn rust. In hull and boat restoration, walnut shell granule is a more controlled option when the goal is stripping rust underneath while protecting the paint layer. Tell us the surface condition and target and we'll suggest the right band, confirming with a sample on high-volume requests.
How many times can the abrasive be reused?
On lines with a reclaim system, the grain cycles several times; we don't give a fixed figure because the exact count depends on the application, pressure and target surface. Organic abrasive works by breaking down, so a portion turns to dust with each cycle and needs a fresh batch as dust content rises. Costing on cycle count rather than a single-bag price gives a more realistic result.
Do you share a mesh and hardness list?
We don't publish a fixed list, because these values change from batch to batch with the source, harvest and grinding — a published table doesn't represent the material that reaches you. Calibre is matched to buyer request; on request, a sample of the batch to be shipped is shared.
What's the difference between domestic delivery and export?
Domestically we deliver to workshops, shipyards and industrial plants by truck; the process is shorter, quantities more flexible, and the sample-approval step moves faster. Export brings in 20ft or 40ft HQ containers, standard Incoterms such as FOB/CIF, and a paperwork flow including the certificate of origin. Calibre matching works the same way on both sides; sample approval is added for high-volume requests.
