In the past, grinding mills were typically lined with cast metal linings of varying steel or iron alloys, and lining system selection was typically driven by level of wear protection and cost. As materials technology and design technique has advanced, today many superior alternatives exist to metal linings.
Rubber compounds have been developed to protect mill shells from wear, while new cast alloys and wear resistant plates can be bonded into rubber to withstand high impact abrasiveness. There is a greater understanding of how mill lining systems influence mill performance. Operators now select mill lining systems on more criteria including ability to deliver mill process performance, wear resistance, ease of installation and safety. Furthermore, return on investment and total cost of ownership models are important factors in the decision making process, rather than cost alone.
