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. The term “comminution” refers to the size reduction and sorting of mining, mineral and aggregate materials.
Available in the SP 100, SP 200, SP 300 and SP 400 models, and ranging from 100 to 400 hp, the Enduron SP series cone crushers deliver one of the highest production-capacity-per-feed ratios in the industry.
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 percent 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 degrees) 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.
A dust seal system, equipped with an auto greaser, protects the crusher’s lubrication oil from contamination, resulting in longer service life, fewer spare parts replacement and lower costs. The countershaft, which revolves at 800 rpm, provides excellent power transmission.
The spiral beveled gear assembly, aided by the steep mantle slope and longer mantle shaft, improves gearing over competitive models, resulting in better transmission efficiency.
