Metso launches new grinding mill discharge system solution

Metso has launched a new solution for discharge systems that simplifies and speeds up grinding mill relines by 50 per cent and dramatically improves safety for mining operations.

It is an expansion of the company’s Megaliner concept, which was first launched in 2012.

The Megaliner for discharge systems has up to 70 per cent fewer parts, integrating dischargers, grates, lifter bars ad filling segments into one unit.

It also has a minimal number of attachment points, and he bolts used to attach the liners are inserted from the outside of the mill. This means no workers are needed in the danger zone inside the mill and works can instead be performed on steady platforms.

Liner bolts are much shorter and well protected from dust, corrosion and general mechanical damage, helping to make then longer lasting and easier to remove. This helps make knocking out the bolts up to 70 per cent faster and eliminates the risk for risky or expensive recoilless hammers.

Metso Vice President, Mill Lining Solutions, Anssi Poutanen said the discharge system of a grinding mill is the most complex and time-consuming part of the mill to reline.

“There are also significant risks involved when changing out heavy liners in a tough environment under time pressure,” Poutanen said.

“We are therefore thrilled to be able to offer a faster, but at the same time much safer solution that will reduce risks and increase uptime for our customers.”

The Megaliner has been installed in more than 30 mills and has helped mining customers increase uptime and safety. The latest release means Metso can now offer Megaliner for all sections of horizontal mills – the head, the shell and the discharge system. Megaliner is suitable for large AG, SAG and ball mills where modern liner handlers are available.
