Two new Kleemann mobile jaw crushers featuring exclusive EVO technology were introduced to the North American market at Conexpo-Con/AGG 2014 in March. The Mobicat MC 110 Ri EVO and MC 110 Zi EVO mobile jaw crushers feature a crusher inlet of 28- x 44 inches, and will achieve outputs of up to 300 tons per hour. Mobicat EVO mobile jaw crushers utilize direct drive crushers and electric drives for the vibrating conveyors, belts and the prescreen. This permits extremely efficient operation with low fuel consumption, and allows optimal loading of the crusher.
The MC 110 Ri EVO has a vibratory feeder with integrated grizzly, while the MC 110 Zi EVO incorporates a vibrating feeder with an independent, double-deck, heavy-duty prescreen. Wirtgen says wear in these plants is reduced because medium and smaller gradations bypass the crusher, and an increase in end product quality is achieved through discharge of fines via side discharge conveyor. Also, a bypass flap provides easy diversion of the material flow, eliminating the need for a blind deck.
Both new models in the Mobicat EVO series have been redesigned from scratch, thus allowing the combination of features. New features such as hopper walls integrated in the chassis, and a fully hydraulic crushing gap adjustment via touch panel, coupled with tried-and-tested concepts like an independent double-deck prescreen (in the Z model), make these plants even more versatile and efficient than their predecessors. Both machines also feature a lighter transport weight to ease portability, with the MC 110 Ri EVO weighing 85,000 pounds, and the MC 110 Zi EVO weighing 87,100 pounds.
