美国原子能委员会与加拿大的Potash有限公司宣布,世界上体积最大和功率最强的采矿机—Orebiter业已制成,它重400吨,由4160伏、2600马力的空冷电动机驱动,目前在加拿大Lanigan碳酸钾矿使用。该机采高可达17英尺,与回转式联合采矿机相比,回收率高40%以上(因为后者采高只有11英尺,故在底部遗留下有用的矿石)。原子能委员会报导Orebiter每小能生产能力为1100吨。藉助Allan Braolley PLC-3计算机控制两个切割臂,为了区别矿石和废石的不
The Atomic Energy Commission and Canada’s Potash Ltd. announced that the world’s largest and most powerful mining machine, the Orbiter, has been manufactured. It weighs 400 tons and is powered by a 4160-volt, 2,600-hp air-cooled electric motor. At present, the Lanigan Potash Mine use. With a height of up to 17 feet, the recovery rate is more than 40% higher than that of the rotary joint miner (because the latter only measures 11 feet high, leaving valuable minerals on the bottom). The Atomic Energy Commission reports that Orebiter has a capacity of 1,100 tons per hour. With Allan Braolley PLC-3 computer control of two cutting arms, in order to distinguish between ore and waste rock
