Metso expands successful Megaliner(TM) concept to include grinding mill heads

Metso Corporation's press release on October 27, 2015 at 1:00 p.m. EET

The new Metso Megaliner(TM) for grinding mill heads provides the same benefits as Metso's original Megaliner(TM): safe installation and maximized availability. Downtime is costly for grinding mills. With Metso Megaliner(TM) for grinding mill heads, installation time is much faster as the liner has much fewer attachment points and the number of liner components is reduced by up to 80 %.

Metso has expanded its light-weight Poly-Met Megaliners(TM), concept with the new Megaliner(TM) for mill heads. Like Metso's other Megaliners(TM), this newest offering increases productivity in mills and makes maintenance and installation work safer than it is with traditional liners. 

Suitable for AG, SAG and ball mills, the easy-to-install Megaliner(TM) for mill heads is larger than conventional liners - and yet still light enough to be handled by the same 7- to 8-axis liner handlers. The Megaliner(TM) is also less prone to cracking than other lining types commonly found in this kind of application.

The Megaliner(TM) for mill heads minimizes the number of components to be installed by integrating multiple lifter and shell plate rows and providing the option to include filling segments. Fewer installation points speed up the installation and change-out process, as well. The reference installation of the Megaliner(TM) for mill heads on a 38' AG mill shows that installation time was reduced by 30 %, and there is potential for even further improvements.

Safe and quick installation

Megaliner's(TM) innovative attachment system improves worker safety during installation and change-outs; there is no need for workers to be in the danger-zone of the liners since the liner bolts are attached from the outside of the mill. The Metso Liner Positioning System allows the liner handler operator to act alone and position liners without the guidance of others inside the mill. Bright guiding markers make positioning and alignment even easier.

Removal is also safer and quicker. The threaded portion of the standard hex-head liner bolt is protected from dust, corrosion and general mechanical damage. Once loosened, it is often possible to remove the liner bolts simply by hand-turning them. Pneumatic or recoilless hydraulic hammers are usually not needed for liner removal, as gravity helps to do the work.
