Metso’s Megaliner Poly-Met shell liner

Metso’s new Megaliner Poly-Met shell liner is said to keep downtime in large mills to a minimum, utilising an innovative design that offers speedy replacement. “It also improves worker safety during maintenance, as the liners are bolted into position from the outside of the mill, so workers do not need to stand in the ‘drop-zone’ of the liners,” says Metso. Megaliner uses larger-than-average liners, and these can still be placed with the same 6- to 8-axis liner handlers used with many large autogenous mill

448 Metso’s new Megaliner Poly-Met shell liner is said to keep downtime in large mills to a minimum, utilising an innovative design that offers speedy replacement.

“It also improves worker safety during maintenance, as the liners are bolted into position from the outside of the mill, so workers do not need to stand in the ‘drop-zone’ of the liners,” says Metso.

Megaliner uses larger-than-average liners, and these can still be placed with the same 6- to 8-axis liner handlers used with many large autogenous mills.

“The Megaliner is suitable for large AG mills with large trunnions and where modern liner handlers are available. Each Megaliner element integrates multiple lifter and shell plate rows, and covers an area up to 4m2. The rubber/metal composite liner weighs between 30% and 60% less than metallic liners of a similar size,” says Metso.
