Duralox mill lining last much longer than other lining materials such as steel, rubber, felsite, granite, porcelain, steatite and high alumina ceramic containing 85% to 90% Al₂O₃.

Duralox mill lining bricks feature tongue and groove design to produce an interlocking lining pattern, which holds the bricks inseparably tight and prevents them from falling apart.

Duralox bricks with controlled dimensions and sharp edges will require small amount of adhesive/cement for fixing and filling of narrow joints which prevent bricks from chipping and spalling of their edges.
