乌龙泉矿破碎车间生产流程,经过三期扩建后,在石灰石系统,缓冲矿仓下边采用1000×2000毫米中型板式给矿机,随着矿石含泥多,增加大洗矿机和产量逐年增长等生产条件的变化,使这台给矿机经常在泥水中超载运行。其缺点是:结构复杂,生产能力小,最大处理量185吨/时,维护和检修工作量大,每月就得中修一次,更换300余个加工零件。由于条件差,维护检修困难,事故多,影响生产时间多,几乎每班都得停产检修,成为当时生产流程的一个难关。在毛主席亲自批示的《鞍钢宪法》指引下,破碎车间维修工人发扬了自力更生的革命精神,参照兄弟单位 Wulongquan mine crushing plant production process, after three expansion, in the limestone system, the buffer ore below the use of 1000 × 2000 mm medium plate feeder, with ore containing more mud, increase the large washing machine and output growth year by year Changes in production conditions, so that this machine to the mine often overload operation. The disadvantage is: the structure is complex, the production capacity is small, the maximum capacity of 185 tons / hour, maintenance and overhaul workload, you have to repair in a month, to replace more than 300 processing parts. Due to poor conditions, maintenance and repair difficulties, accidents, affecting production time and more, almost every class have to stop production and maintenance, became the production flow of a difficult time. Guided by the “Anshan Iron and Steel Constitution,” which was personally authorized by Chairman Mao, the workers in the crushing workshop carried forward the revolutionary spirit of self-reliance.
