在毛主席无产阶级革命路线指引下,1958年我国开始了干式自磨机的研制工作,于1959年试制成功φ4.0×1.2米干式自磨机,并于1960年1月在鞍钢烧结总厂进行了单机试验。1964年对湿式自磨机也开展了研制工作。无产阶级文化大革命以来,广大工人、干部、技术人员批判了“洋奴哲学”“爬行主义”等修正主义路线,使自磨矿的研制应用工作得到了迅速发展。1966年以后在鞍钢烧结总厂试验厂进行了大量的干式自磨试验,不到两年的时间取得了丰富的实践资料;410厂和长沙黑色金属矿
Under the guidance of Chairman Mao’s proletarian revolutionary line, in 1958, China started the research and manufacture of dry self-grinding mills. In 1959, it successfully experimented with φ4.0 × 1.2 m dry self-grinding mills and sintered in Anshan Iron and Steel Co., Ltd. in January 1960 Plant conducted a single test. In 1964 wet self-mill also carried out research and development work. Since the Great Proletarian Cultural Revolution, the majority of workers, cadres and technicians have criticized the revisionist line such as “Western Slavery Philosophy” and “Creepism,” so that the research and application of self-grinding has been rapidly developed. Since 1966, a large number of dry self-abrasion tests have been carried out in the pilot plant of the Ansteel Sinter Plant. In less than two years, a wealth of practical data has been obtained. The 410 plant and the Changsha ferrous metal mine
