Enhanced for today’s crushing needs, and using the latest in design and modeling software, Metso’s SUPERIOR® 60-110E primary gyratory crusher provides a redesigned Spider, a one-piece bottomshell and a new rim liner retention system. These improvements and redesigned components are also interchangeable with existing 60-100 MK-ll crushers. The SUPERIOR® 60-110E is FEA-analyzed to reduce stresses, increase reliability and enhance performance.
Additional benefits include a 20% reduction in weight but with no reduction in capacity, an increase from 514 rpm up to 600 rpm, the option of being retrofitable (with nominal modifications) and reduced installation and transportation costs.
Four key design elements drive the SUPERIOR® 60-110E as a serious market addition:
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.
Bottomshell design
The redesigned single piece bottomshell reduces components and installation time. Using strain gauge data from gyratory crushers in use, newly created FEA models evaluated the bottomshell for high stress areas and new solutions were found, resulting in increased reliability.
Topshell design
The redesigned topshells 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.
Additional features
An additional feature of the SUPERIOR® 60-110E includes an 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.
As a bonus feature, the Spider, bottomshell and/or topshell can be adapted to fit on existing 60-110 MK-ll crushers.
