良山铁矿选矿厂在着重抓好铁精矿生产的同时,抓设备管理和技术改造,1988年完成十几项小改小革项目,取得了显著成效。(一)碎矿老三段7号胶带机改造原碎矿老三段7号胶带宽800毫米,由于给矿量大,胶带不够宽,加之胶带时常跑偏,致使胶带机操作困难,时常出现“埋胶带,烧电机”现象。对此,于1988年8月,对原碎矿7号胶带进行改造,将胶带宽改为1000毫米,整体支架也重新制造和改装,从而确保了生产的顺利进行。(二)碎矿4号可逆胶带机行车轮的改进原碎矿筛分间4号可逆胶带机行走车轮轴瓦是用油杯加油;因筛分矿仓多(4～5个),行走车轮来回移
Liangshan Iron Ore Concentrator in focus on iron ore concentrate production at the same time, grasping equipment management and technological transformation, completed in 1988 a dozen small change small leather project, and achieved remarkable results. (A) the first paragraph of the crushing ore on the 7th section of the original transformation of the original crushing tape on the 7th section of the tape width of 800 mm, due to a large amount of ore, the tape is not wide enough, combined with the tape often deviation, resulting in difficult operation of the tape machine, often appear “Buried tape, burning motor” phenomenon. In response, in August 1988, the original crushing on the 7th tape transformation, the tape width to 1000 mm, the overall stent is also re-manufactured and modified to ensure the smooth production. (B) Crushing 4 reversible tape drive wheel improvements Crushing sieve room between the No. 4 reversible tape drive wheel bush is the use of oil cup refueling; (4 to 5) because of screening more ore, walking round the wheel shift
