Description
Walnut Shell #7 is an extra-coarse natural abrasive material intended for industrial cleaning and maintenance operations requiring strong mechanical particle contact. Its large particle structure makes it suitable for applications where loose deposits and surface contamination need to be disturbed efficiently.
This grade is best considered for cleaning-focused applications rather than fine finishing. The lightweight nature of walnut shell provides an alternative abrasive medium for selected industrial processes where the characteristics of conventional mineral media are not preferred.
