This Thyssen Krupp limestone stacking and reclaiming system can pile up as much as 7,500 metric tons of material per hour. Krupp Fordertechnik GmbH's bulk materials handling unit in St. Ingbert-Rohrbach, Germany, filled the bill by constructing a circular limestone stacking and reclaiming system about 125 meters in diameter, with a capacity of approximately 90,000 cubic meters. The core bulk handling components are produced partly in Germany and partly by Indonesian manufacturers. The stacking system arrived in February and will begin operating when the plant is commissioned in the near future. The entire stockpile is housed with-in a domed structure.
Limestone is conveyed from the middle of the stockpile to the system's stacker.
The Krupp engineers installed a bridge-type scraper to reclaim up to 750 metric tons per hour from the stockpile to feed the cement plant. Well, NASA scientists have come up with another application of Faraday's discovery which, as you might have guessed, is out in space. In an upcoming experiment, NASA will test an electromagnetic tether as a means of decreasing the altitude of an Earth-orbiting spacecraft. The whole string will pay out from the second stage of a Delta II rocket, to be launched from Cape Canaveral Air Station in August 2000. An electrodynamic tether generates a current in its wire as it moves through the magnetic field of the earth's ionosphere.
