34 AGGREGATES MANAGER / December 2016 ROLLOUTS MCLANAHAN CORP. SCREEN FEATURES INDEPENDENT CROSS MEMBERS McLanahan's MAX Series Vibrating Screen separates coarse feed materials from finer materials. Available in a range of sizes from 6- by 16-feet to 8- by 24-feet, the screens feature a low-headroom design to fit into existing structures and operations without re- work. The screens are built with maximum steel strength so they can withstand heavy loads. Sideplates are fully bolted construction to avoid crack propagation and feature cross beam inspection ports for easier operator inspection. Independent cross members allow for individual replacement of worn screen sections. A direct drive system elimi- nates the requirements for a pivoting motor base to keep belt tension at startup. McLanahan Corp. | www.mclanahan.com SANDVIK CONSTRUCTION JAW UPDATE ADDRESSES FINES Sandvik's QJ341+ portable jaw crusher incorporates a double-deck pre- screen as standard. Said to provide high amplitude for improved separa- tion, the unit can remove a large amount of fines to improve efficiency and productivity, while reducing wear. A new telescopic natural fines conveyor, with a discharge height of 10 feet, 3 inches, deals with the in- creased flow of pre-screened material. The dirt chute fea¬tures a steeper angle for faster transfer, as well as improved handling of sticky material. Its three positions allow material to pass the pre-screen grizzly to be di- verted onto either the main conveyor or natural fines conveyor, with the middle position able to feed either the main conveyor or natural fines conveyor. An improved self-locking hopper allows for quick setup from the ground level. Operators can choose between a Cat and Volvo engine. Sandvik Construction | www.sandvik.com MCLANAHAN CORP. ENHANCED CONE DESIGN The McLanahan Symons Principle (MSP) Cone Crusher is said to deliver minimal downtime processing optimal amounts of material, ultimately leading to a faster return on investment. Using improved factors of perfor- mance such as balanced eccentric, higher speeds, fulcrum point position, and stroke to enhance the Symons Principle, the MSP creates torque and resultant crushing forces that McLanahan says are as effective as any cone crusher on the market. The eccentric stroke is designed to work with the eccentric speed and fulcrum position to produce higher yields and minimize recirculating loads. McLanahan Corp. | www.mclanahan.com SANDVIK CONSTRUCTION CONE CRUSHER EVOLUTION Sandvik says its CH540 represents the next step in a new generation of cone crushers and is suitable for operators who want to increase production capacity, eliminate bottle- necks, reduce cost per ton, or improve product quality. The high-capacity crusher comes standard with Sandvik's new automation and control system — SanRemo for Crushers. A dump valve ensures quick, safe tramp relief while wear parts have been adapted for lon- ger life. Minimum welding is used on the crusher, which has also been designed for faster change out of manganese. With feed sizes ranging from 1.7 to 7.3 inches, the crusher's capacity is rated at up to 295 tons per hour. Sandvik Construction | www.construction.sandvik.com
