In mining, two of the harshest applications for cast components are in mill-linings and in chute-linings. Both are typically subject to extreme levels of erosive, corrosive and gouging wear. Over the decades, Mitak has developed a range of singularly effective HCWI alloys each suited to these specific mining applications.

The company has built the quality of its HCWI products on the expertise of its metallurgical and production teams. As such, the company specialises in abrasion-resistant alloys and possesses extensive expertise in the area of corrosion retardation. Castings are all through- hardened with their final hardness being from 550BHN to in excess of 713BHN, depending on the application.

The alloys conform to various international standards, the two most notable specifications being BS4844 Part 3 and ASTM A532 Class 3, and typically have a chromium content of 12% to 35% and a carbon content of 1.5% to 3.5%.

Mitak manufactures liners for use in wet or dry milling applications, and for ball, rod and fully autogenous grinding (FAG) mills. These manufacturing processes are supported by Mitak's considerable metallurgical and application knowledge. Over the past 45 years, Mitak has manufactured nearly 500 sets of mill liners and, in the process, has built up a vast reservoir of expertise about a wide range of comminution and materials handling applications and enabled the development of specialised alloys that meet the requirements for world-class mill liner standards.
