Portable Plants Jaw cone crushers tout enhanced performance levels Kleemanns Mobicat MC 110 Ri EVO and MC 110 Zi EVO mobile jaw crushers feature EVO technology that helps productivity The MC 110 Ri EVO has a vibratory feeder with an integrated grizzly while the MC 110 Zi EVO has a vibrating feeder with an independent double deck heavy duty prescreen Both feature a crusher inlet of 28 in x 44 in Medium and smaller gradations bypass both jaw crushers causing wear in these systems to be reduced A bypass flap provides diversion of the material flow which eliminates the need for a blind deck Both machines have lighter transport weight to ease portability with the MC 110 Ri EVO weighing 85000 lbs and the MC 110 Zi EVO weighing 87100 lbs Kleemann integrated hopper walls in the chassis of both jaw crushers to increase the plants versatility Users can also benefit from the long articulated crusher jaws on both the MC 110 Ri EVO and MC 110 Zi EVO Additionally the mobile jaw crushers use direct drive crushers and electric drives for vibrating conveyors belts and prescreen to permit more efficient operation Kleemann also offers the Mobicone MCO 9i EVO and MCO 9i S EVO mobile cone crushers to the aggregates industry Both machines assist with secondary or tertiary crushing and are Tier 4 Final compliant The MCO 9i S EVO provides a discharge conveyor mounted final classifying screen with an oversized aggregate return conveyor to allow a closed material cycle and production of final particle sizes without a stand alone screen The oversize can be optionally discharged through the swivel mounted return conveyor at the side Both mobile cone crushers diesel electric drive provides low fuel consumption in a compact design Optional crusher anti spin and automatic lubrication functions create high crushing capacities and equipment durability To ensure power is delivered to where its needed the crusher housing design permits more than 287 hp of the total 332 hp drive to be continuously available to the crusher which ensures a maximum throughput of up to 287 tph Both mobile cone crushers come with a continuous feed system CFS where each step material goes through is wider than the width of the one before it eliminating choke and wear points CFS also manages a more equal loading of the crushing area in which conveying frequencies of the feeder trough and prescreen are adapted independently of each other to the level of the crusher to enhance performance www wirtgenamerica com 14 PIT QUARRY May 2015 www pitandquarry com
