0

The new SUPERIOR 60-110E primary gyratory crusher enhance today’s crushing needs, and use the latest in design and modeling software. Metso’s SUPERIOR 60-110E primary gyra­tory crusher provides a redesigned Spider, a one-piece bottom shell and a new rim liner retention system. These improvements and redesigned com­ponents are also interchangeable with existing 60-110 MK-ll crushers. The SUPERIOR 60-110E is FEA-analyzed to reduce stresses, increase reliability and enhance performance. Additional benefits include a 10% reduction in weight but with no reduction in capacity, an increase from 514 rpm up to 600 rpm, the option of being retrofit-table (with nominal modifications) and reduced installation and transportation costs.

SUPERIORprimary gyratory crushers are suitable for:

  • The most demanding crushing applications
  • Stationary and semi-mobile applications
  • The hardest rock and ores
  • Surface and underground operations

Main customer benefits and key features of the SUPERIOR 60-110E primary gyratory crusher:

  • Spider assembly. Using FEA and strain gauge data, the Spider was redesigned to remove stress risers and concentrations, producing a more reliable design. The Spider now features an arched opening to reduce material bridging. New arm shields and Spider cap provide improved protection to the Spider.
  • Bottom shell design. The redesigned single piece bottom shell reduces components and installation time. Using strain gauge data from gyratory crushers in use, newly created FEA models evaluated the bottom shell for high stress areas and new solutions were found, resulting in increased reliability.
  • Top shell design. The redesigned top shells were analyzed using FEA tools to eliminate vertical rib stress risers while utilizing horizontal bands to protect against concentrated loads. High strength banded construction provides trouble-free operation and the removal of vertical ribs has decreased stresses. Tapered flanges offer simplified construction.
  • Rim liner retention. The new rim liner retention system utilizes bars and clips welded in place. This arrangement connects all of the spider rim liners together, making for simple, easily installed components. No bolts are required, making the rim liners easily replaceable and are tied together to act as one piece.
  • Upgraded mainshaft assembly with a patented bearing ring that releases the pressure of the headnut for mantle change-out. This eliminates the potential for damage to the headnut or mantle and affords simple replacement of one less expensive component.
