Loose Grain Abrasive

Loose grain abrasives are widely used throughout the finishing industry for blasting applications (prep for coatings) primarily, but can also be used as an additive to a vibratory deburring process to accelerate the cutting action.

  • Aluminum oxide is very popular and is used in many different items other than finishing (e.g. anti-skid surfaces, laminate flooring (that’s why it is so durable) and, of course, sandpaper). Sizing ranges from tumbling chips to fine powder abrasives in brown or white.
  • Glass beads are another popular product for finishing and are used in many different applications. The peening action provides minimal stress relief, along with a very nice and even satin finish. Automotive engine parts and aluminum or stainless final surface appearances use these, as do highway line paints for reflectivity.
  • Silicon carbide loose grain abrasives are more specialized per application, but brazing/soldering applications may need to use this. Vibratory tumbling medias in silicon carbide do so for the same reason.
  • Corn cob maize: 3 standard sizes; can be treated for polishing processes.
  • Walnut shell, crushed: 3 standard sizes (fine, medium and coarse); light or fine deburring and the main product for your red or green treated shells (polish)
  • Plastic blasting media: Crushed plastic in different MOL/Rockwell hardnesses. Blasting for paint removal when you cannot change the base surface profile.

There’s even more variety than can be written down. Here is where all of our years, time and experience come into play. We know your specialized business and we’ll sell you the right system, including for loose grain abrasives. Consulting and sample part work is important in verifying processes and machinery prior to purchase.
