漓渚铁矿是国内最早采用湿式自磨工艺的选厂之一。由于当时国内还没有湿式自磨厂投产,设计是按干式自磨试验结果并参照国外湿式自磨经验,估算选用一台φ5.5×1.65米湿式自磨年处理50万吨原矿。1973年下半年投产以来,由于原矿品位低、磁铁矿嵌布粒度细、矿石坚硬而具有韧性等主要原因,自磨机台时能力只能保持40～43吨。 The Lizhu Iron Mine is one of the earliest factories to adopt wet self-grinding process in China. Because at that time there was no wet self-mill factory in China, the design was based on the dry self-abrasion test results and with reference to the experience of wet self-abrasion in foreign countries. It was estimated that 500,000t of raw ore was processed using a φ5.5 × 1.65m wet self-grinding mill. Since the second half of 1973 put into operation, due to low ore grade, magnetite embedded fine grain size, toughness and toughness of the ore and other major reasons, since the grinding machine capacity can only maintain 40 to 43 tons.
