Overview  : 
Corncob particles are highly absorptive. That characteristic combined with the all-natural, inert, biodegradable and free-flowing attributes makes corncob particles an ideal carrier for feed additives and the active ingredients of insecticides and fertilizers.

Vibratory finishing and tumbling are mass finishing processes where the abrasive and absorbent characteristics are generally both desirable. Corncob grit polishes and deburs parts and at the same time cleans and dries parts. Oils and other liquids from wet mass finishing processes are absorbed. Grade selection is typically based upon the finished surface profile desired and the diameter of any holes or cavities in the part. The selected grade should not contain particles that would lodge in part openings.

Corn Cob Grit

Grit blasting with corncob particles is accomplished with the same equipment as used for sand blasting. Because corncob grit is considerably less aggressive than sand, it is often categorized as a "soft abrasive" (corncob grit has a 4.5 Mohs hardness). Corncob grit does not etch glass or foul bearings and is frequently used to clean electric motors and machinery with hydraulic cylinders. Other applications include: smoke damage and residue clean-up; mold cleaning; plant maintenance; and loose and flaking paint removal. It is ideal for wood, aluminum and fiberglass substrates.

Unlike mass finishing processes, blasting with corncob grit is not as predictable. Each job tends to have unique characteristics which do not allow for estimating precise media usage or outcomes. We recommend testing a couple of grades to determine which offers the best performance. We will box and ship 50-pound bags anywhere in the  USA for $30.0 per bag. Small samples are available at no charge.
