Walnut Shell blasting – biodegradable abrasive

Walnut Shell blasting

Walnut shell blasting is a hard, chemically inert, nontoxic, and biodegradable abrasive.  It is processed from cleaned eastern black walnut shells that are grown in the mid-western and central eastern United States.  It has a variety of uses and is available in six primary sizes: 6/10, 8/12, 12/20, 20/30, 30/100, and -100.

Ground black walnut shell is used as an abrasive to polish and clean soft metals, fiberglass, wood, and stone.  Because it is resistant to breakdown, it can be recycled many times in a pressure blast application.  Walnut shell provides an excellent finish without scratching or pitting.

Corn Cob blasting

Crushed corn cob media are made from the woody ring portion of the corn cob.  This portion of the cob is separated, dried, ground, air-cleaned, and then classified over screens of various mesh sizes.  They are available in granules ranging from 1/4” to a fine powder.

Qualities of crushed corn cobs that make them ideal for pressure blasting include its mild abrasiveness, absorbency, and resilience to attrition.  Advantages of using corn cobs for blasting include the elimination of masking, elimination of solvents and pollution concerns, non-sparking and non-toxic operation, non-silica content, and the fact that it is organic and biodegradable.
