Weir Minerals features the Enduron SP series cone crusher line as part of its expanding comminution product portfolio, which includes crushers, screens and high-pressure grinding rolls. Available in the SP 100, SP 200, SP 300 and SP 400 models, and ranging from 100 hp to 400 hp, the cone crushers deliver one of the highest production-capacity-per-feed ratios in the industry, according to Weir. Cone crusher adjustments and operations are fully automated, and a hydraulic adjustment and locking system allows adjustments under full load.
The power of a high eccentric speed—up to 375 RPM—with a larger crushing chamber results in more tons per hour produced, when compared to standard cone crushers. In fact, the SP series cone crushers deliver 30% to 40% more capacity per hour than spring-type cone crushers, according to data and operational analysis. Additionally, the Enduron SP series cone crushers have a high pivot point and increased mantle slope (50°) that result in a high-quality, cubical product.
Adjustments and operations are fully automated, and run from a simple-to-operate onboard control. A wireless remote control also is available. All Enduron SP series cone crushers are equipped with two adjust-on-the-run planetary gearbox hydraulic motors that allow the operator to unlock, adjust and relock the bowl under full production. This hydraulic adjustment and locking system also means that liner changes can be completed in less than two hours. The hydraulic tramp iron relief system provides automatic clearing for uncrushable material.
