  • Ceramic vs. Zirconia Abrasives Which is the best option

    Zirconia will have a much longer life than aluminum oxide, be more fiable, and provide a cooler sanding / grinding experience. Zirconia sanding discs and zirconia sanding belts are the most popular types of abrasives found in the marketplace. Although it is stronger than aluminum oxide, zirconia may have difficulties grinding mill scale.

    A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
