Metso’s Nordberg MP1250 cone crusher is claimed to provide up to 25% more capacity with an increase in power to 1,250 hp, while maintaining the same physical footprint as the company's MP1000 model. According to Metso, the MP1250 offers nearly a dozen key features and benefits that include: a more robust bearing design that allows a wider range of application and maximizes bearing life; a redesigned mainframe for improved durability; a new eccentric design provides improved surface finish and protects the eccentric in the event of overload; and a new head bushing and socket design reduces head spin during no-load operation without the need for a mechanical clutch assembly.

Design improvements have been made to the mantle locknut, hydraulic tramp protection system and bowl adjustment and bowl removal, along with faster hydraulic re-pressurization times. Many of the upgrade features are also available as individual components. Metso also has developed an MP1000 retrofit kit, which includes a new sleeved, high-throw eccentric; large counterweight with bolt-on guard; upper head bushing; head ball; and socket liner.
