Page 52 of 55 Crushing & Breaking October 2018 | 51 Products Kleemann High-performance and enhanced aggregates processing technol- ogy built into Kleemann products like the Tier 4 final-compliant Mo- birex MR 130 Zi EVO2 impact crusher and the smaller MR 110 Zi EVO2 are boosting productivity and product quality for operators. These mobile impactors can be equipped with an optional, high- ly productive secondary vibrating screen with extra-large screen- ing surface mounted on the discharge conveyor. This secondary screening unit can produce spec material, potentially eliminating the need for a separate screen. The feeding unit has hydraulically folding hopper walls and locking system, which speeds setup. A vibrating, independent double-deck prescreen between hopper and crusher eliminates fines from the product flow before they ever enter the crusher, reducing wear and cutting fuel costs. Inlet Geometry These crushers feature a new inlet geometry, which allows even better penetration of the material into the range of the rotor. Also, the wear behavior of the new C-form impact ledges has been im- proved to such an extent that the edges remain sharper longer, leading to improved material shape. The rotor ledges are held se- curely by a new and extremely user-friendly clamping system, which means that they can be changed even quicker, and thus contribute to greater plant uptime. Outstanding performance is made possible in part by the extremely efficient direct drive, with which the machines are equipped. A lat- est-generation diesel engine transmits its power almost loss-free directly to the flywheel of the crusher, via a robust fluid coupling and V-belts. This drive concept enables enormous versatility, as the rotor speed can be adjusted in four stages to suit different processing applications. The Kleemann Continuous Feed System (CFS) manages a more equal loading of the crushing area, in which the conveying frequen- cies of the feeder trough and the prescreen are adapted inde- pendently of each other to the level of the crusher, thus significantly boosting performance. For the optional version with secondary screen mounted, the over- size gradation return conveyor has been redesigned from the pre- decessor models, eliminating a vertical bend and integrating the transfer chute at the feed hopper. New SPECTIVE Control System The MR 130 Zi EVO2 is equipped with the new SPECTIVE con- trol system. SPECTIVE is simple to understand and supports the operator in his or her work. The use of clear symbols makes all plant functions recognizable at a glance. Similar in presentation to a smart phone, the operator is guided by the control system, re- ducing the potential for operating errors. In addition, data relating to the machine operation can be retrieved via the control system, and the levels of diesel and lube oil, for example, can be viewed in the plant cockpit. Hydraulic Gap Adjustment With these new Mobirex impact crushers, the fully hydraulic adjust- ment capability of the crushing gap permits greater plant uptime, while improving quality of end product. Not only can the crushing gap be completely adjusted via the touch- panel electronic control unit, but the calculation of the zero-point is possible while the rotor is running. This ability to accurately set the crusher aprons from the control panel with automatic detection of zero point and target value setting saves time, and improves the overall efficiency and handling of the crusher. KPI-JCI Kolberg-Pioneer Inc. (KPI) has made numerous updates to its FT3055 track-mounted jaw crusher plant. The jaw plant now features versatile and powerful, American-made hydraulic pumps for better support and reliability. In addition, the FT3055 also features a new feeder/hopper, which is commonly used on the FT4250, with greater spare parts availability and shop commonality, to better serve customers. The push-button or touchscreen display has been upgraded for increased memory and performance to ensure that producers are using the latest technology. In addition to hardware updates, the crushing plant showcases a new, functional industrial-style design. KPI designers have improved the overall appearance of the plant by moving hoses and other components inside the frame, which improves the overall equip- ment design and further protects those parts.
