Metso's in-pit crushing solution reduces emissions and improves safety at major Russian iron ore mine - Seite 2

The Metso system consists of an AF10-84 apron feeder, a Nordberg^® C200(TM) jaw crusher, an RF2448 mining screen, a Nordberg^® HP800(TM) cone crusher, conveyors as well as custom-made electrics and automation systems, all feed and support structures, and maintenance equipment. Metso also provided installation supervision, startup support and commissioning.

Easier maintenance and reduced energy consumption

Clever engineering and attention to detail bring additional benefits. The conveyors, part of Metso's new Nordberg^® NCHD mining range, are maintenance friendly and provide superb protection against the freezing temperatures. The hopper design features a notable buffer that reduces wear lining consumption. In addition, all components are controlled by a highly sophisticated, Metso-designed control system, which keeps the flow rate constant and optimizes the load on the crusher. This enables improved energy consumption per ton compared with uncontrolled crushing stations of the former generation.

To maximize safety, the system includes a comprehensive set of access and maintenance platforms for all machinery. Metso also designed and installed guards and covers, mostly on the conveyors and crushing stations, which comply with the latest standards. Electrical features include a very safe maintenance mode with local control boxes, as well as lockable motor isolation switches that are appreciated in all industrial plants, providing increased safety for maintenance personnel.
