mill liners Archives - International Mining

He notes that the traditional use of steel liners in large SAG mills presents a number of challenges. For instance, there may be bending stress inside the steel liner due to inexact fitting on the mill's curved surface, and the higher rigidity of steel, compared with rubber, makes it less than optimal for absorbing the energy of rock material ...

How an issue with SAG mill dischargers become a nine-year ...

At an open pit polymetallic mine in Mexico, there were problems afoot in the two 38 ft diameter SAG mills. At the heart of things: the design of the steel discharger linings. Adopted to reduce the number of lining pieces and thus shorten installation time, the design was having some unintended – and serious – consequences.
