Cone Crusher Handles 2,240 Tons/Hour

Claimed to be the world’s largest cone crusher, the new Raptor XL1100 from FLSmidth Excel can deliver throughput of up to 2,240 t/h (2,000 mt/h) at a 1-1/3-in. (35-mm) closed-side setting. Ideal for high-tonnage mining operations, the unit handles feed size up to 24 in. (620 mm) and allows a reduction ratio of up to 6:4. The XL1100 employs spiral-bevel gear technology for durability and reliability while minimizing gear noise. Available with shorthead or standard bowls, the XL1100 cone is suited for secondary, tertiary and quaternary applications.

The crusher incorporates a heavy-duty hydraulic design that improves the durability of the tramp release components, while greatly reducing the number of accumulators required. This hydraulic configuration reduces ongoing maintenance costs while delivering superior performance and reliability. A “fail safe” hydraulic protection system also provides an external relief that prevents severe structural overloads if an accumulator bladder should fail—protecting both the hydraulic system and the crusher. An additional safety feature standard on all Raptor models is the counterclockwise rotation crushing action that protects the machine if adjustment ring movement is excessive or if the ring gear brake fails.

Advanced overload sensing technology detects crushing force overload. A simple alarm is activated, or the system can be automated to take corrective action. This same advanced automation system can be used to optimize crusher performance, with feed control, setting adjustment and monitoring of all critical lubrication and hydraulic parameters. Powered by a 1,000 hp motor, FLSmidth Excel says the XL1100 cone is designed to operate and remain mechanically sound at a wide range of eccentric speeds. Because of this versatility, the eccentric speed can be selected to maximize throughput, size reduction and product yield.
