Organic granules, such as corn cobs or walnut shells, are used in vibratory dryers to dry metal products after vibratory grinding. Dried metal parts become more resistant to corrosion. The granules come in a variety of fraction sizes. The size of the fraction is chosen according to the shape and dimensions of the product. Organic granules do not leave dust particles on the treated surfaces.
Organic granules can also be mixed with a polishing paste and used to polish stainless steel, aluminium or other metals.
