New compact large-capacity primary crusher for above and underground applications

Metso Outotec is launching an extension to its primary gyratory crusher range: The SUPERIOR MKIII 6275UG. The new crusher, which can be used in different types of applications, provides large capacity with significant savings in CAPEX and operating costs.

The crusher was born out of a need for a high capacity underground primary crusher that did not require a primary feeder, scalper, and the associated infrastructure therein.  Additional requirements for an underground crusher were the ability to transport the components down shafts with spacial restrictions, assemble the crusher with minimal need for welding and hot works, and the ability to feed the crusher from 360 degrees around the feed opening; these were all met with the 6275UG MKIII.

The 6275UG crusher’s feed opening is 15 per cent larger than in similar crushers, while also reaching up to 30% more capacity than comparable crushers. Optimized production can be ensured with advanced automation. The up to 10 per cent reduction in station height translates into a remarkable reduction in the CAPEX costs, reaching even 20 per cent.

Some additional key design targets for this new crusher were less downtime and easy maintenance. In MKIII UG, downtime can be reduced by up to 70 per cent thanks to concave replacements with another Metso Outotec proprietary innovation, the Rotable Topshell.

Additional benefits with the SmartStation concept

The SUPERIOR MKIII 6275UG is designed to be part of a SmartStation, where productivity and availability are optimized with sophisticated automation in each phase of the process.

Incoming material analysis is done automatically with VisioTruck, and Metso Outotec Metrics provide analytical dashboards and condition monitoring to ensure optimal crusher performance. A consistent vault level is ensured with automatic crusher adjustments. VisioRock and control system is used for wear compensation.
