Extracting the benefits of high power drive systems

摘要

when Midland Quarry Products (MQP) needed to recover the granite reserves from its Old Cliffe Hill Quarry, it had to overcome the problem that its processing equipment, crushers, screens and rail linked asphalt plant were in its existing New Cliffe Hill Quarry some miles away. And a village lay between the two quarries. Undaunted, MQP came up with a solution: a 720m long tunnel through the hillside to link the two quarries. Now, thousands of tons of rock are transported through the tunnel each day on an overhead conveyor, powered by specially manufactured drive packages comprising Sumitomo high strength Paramax gearboxes and WEG Premium Efficiency motors.
