Metso Outotec says it has signed an agreement to deliver its “industry-leading comminution equipment” to Norilsk Nickel’s refurbishment project at the Talnakh processing plant in Norilsk, Russia.

The contract includes delivery of one SAG mill and two ball mills with a total installed power of 36 MW, as well as two HP series pebble crushers. Metso Outotec will also supply spare parts and consumables, including metallic mill liners, and will supervise the installation of the equipment. The delivery is scheduled for 2022.

While the order value was not disclosed, Metso Outotec said the order has been booked in its December quarter 2020 orders received.

Sergey Dubovitsky, Senior Vice President, Strategy, Strategic Projects, Logistics & Procurement at Norilsk Nickel, said: “The modernisation of the Talnakh processing plant is one of the priority projects for Norilsk Nickel. Its implementation will significantly increase the volume and efficiency of production. To achieve this, we utilise the most modern technologies from Metso Outotec.”

Stephan Kirsch, President, Minerals business area, Metso Outotec, added: “We are pleased to continue our partnership with Norilsk Nickel. The supply of leading-edge equipment from Metso Outotec for the reconstruction of the comminution section at the Talnakh concentrator will enable an increase in the amount of ore processed. Our company has taken part in several projects with Norilsk Nickel to boost throughput rates of the processing facilities, and we are grateful for having been again selected to provide reliable solutions for a project as significant as Talnakh.”

Norilsk Nickel chooses Metso Megaliner for Talnakh concentrator

Norilsk Nickel has recently switched out the chrome and molybdenum alloy lining of a SAG mill at its Talnakh concentrator in Russia as the company looked to increase the life of these all-important wear parts.

Sever Minerals and Norilsknikelremont (a subsidiary of Norilsk) were contracted to complete the mill relining project, using liners supplied by Metso’s global team, which also used the OEM’s Megaliner™ concept.

The new lining is more durable, weighs less and ended up being safer to install than previous the previous lining, according to Norilsk.

A Norilsk spokesperson told IM that the mill lining was replaced with two elements, the Metso Poly-Met; a rubber-steel combination installed on the front-facing part of the mill; and the Metso Megaliner, which has large shell or head liners used to protect the drum.

The spokesperson added: “The cladding manufacturers guarantee that the mill can work for 5,600 hours uninterrupted (that is about eight months non-stop). The previous version required the SAG mill to be stopped for replacement every six months.”

By developing the technology, adopting better project management and using the specialised equipment, Norilsk said it was able to reduce the time taken to replace the mill lining by three days.

The Megaliner is, according to Metso, a new, innovative mill liner concept, dramatically improving worker safety and maximising mill availability. Each shell or head liner covers a large area, has few attachment components and an attachment system which gives a safer working environment for the installation crew, it said.

The weight of the mill lining also came down with the switch from pure metal to a metal-rubber compound, Norilsk said.

“The new mill liner weighs close to 130 t, which is 120 t less than the old mill liner. The average weight of one mill liner element is 1.8 t (elements have different configurations and respective mass),” the spokesperson said.

This reduced weight came with other benefits.

“Due to the lower weight of the capstan, the new mill liner is more wear resistant and better technologically-equipped to cope with an increased number of planned tasks,” the spokesperson explained.
