Agricultural Media

Abrasive Products offers a variety of agricultural media.  The two most common are corn cob and walnut shells.  There are a number of other agricultural media types available other than corn cob and walnut shell, but these two represent most of the usage for this sector of abrasives.  

Both corn cob and walnut shell are derived from grinding cob or walnut shell into a loose grain form.  These products are then sized by a broad range and typically offered in bags.  Both products are very light weight by bulk density.
