New Kleemann Jaw Crushers Introduced at Conexpo-Con/Agg

Two new Kleemann mobile jaw crushers featuring exclusive EVO technology were introduced to the North American market at Conexpo-Con/Agg 2014.

Two new crushers – the Mobicat MC 110 Ri EVO and MC 110 Zi EVO mobile jaw crushers – were among the 41 machines – most of them new i-series products – that Wirtgen America displayed at its 39,600-sq. ft. exhibit.

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. Both feature a crusher inlet of 28 X 44 in.

Either way, wear in the system is reduced because medium and smaller gradations bypass the crusher, with an increase in end product quality through discharge of fines via the side discharge conveyor. A bypass flap provides easy diversion of the material flow, eliminating the need for a blind deck.

Both machines have been completely redesigned with a lighter transport weight to ease portability, with the MC 110 Ri EVO weighing 85,000 lb., and the MC 110 Zi EVO weighing 87,100 lb.

The new Mobicat MC 110 Zi and MC 110 Ri expand Kleemann’s popular EVO Contractor Line of crushers. The new Mobicat EVO series has been redesigned from scratch, thus allowing the combination of new features such as the hopper walls integrated in the chassis – or a fully hydraulic crushing gap adjustment via touch panel – with tried-and-tested concepts like an independent double-deck prescreen (in the Z model), making the plants even more versatile and efficient.

Users will benefit from a newly designed crusher unit with extra-long, articulated crusher jaw. Like the EVO Mobirex mobile impact crushers, the new 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. Beneath the crusher a deflector plate keeps tramp metal from degrading the conveyor belt.

The Kleemann Continuous Feed System (CFS) manages a more equal loading of the crushing area, in which the conveying frequencies of the feeder trough and the prescreen are adapted independently of each other to the level of the crusher, thus significantly boosting performance.

The new Mobicat crushers incorporate a newly designed longer swing jaw, which prevents blocking of coarse material while moving all mounting elements of the crusher jaw from the wear area. In addition, the transfer from the prescreen or the feeder trough is designed so material simply tilts into the crushing jaw, providing an even material flow. With this property and other features the new Kleemann Mobicat MC 110 Ri and MC 110 Zi achieve outputs of up to 300 tons per hour.
