Conveyor tunnel links two quarries

摘要

WEG AND SUMITOMO HAVE COMBINED TO PROVIDE HIGH POWER DRIVE SYSTEMS FOR A UNIQUE 1.5KM TUNNEL CONVEYOR LINKING TWO LEICESTERSHIRE QUARRIES. When Midland Quarry Products (MQP) needed to recover the granite reserves from their Old Cliffe Hill Quarry, it had to overcome the problem that all of their processing equipment, crushers, screens and rail linked asphalt plant were in its existing New Cliff Quarry some miles away. Worse still, a village lay between the two quarries. Undaunted, MQP came up with a highly environmental 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, which was supplied and installed by Whitwick Engineering and powered by specially manufactured drive packages comprising Sumitomo high strength Paramax gearboxes and WEG Premium Efficiency motors.
