本文以缅甸达贡山镍矿项目采矿厂筛分破碎及皮带输送系统为例,介绍红土型镍矿在破碎、管状皮带机运输过程中存在的重型板式给料机给料不均匀、双齿辊破碎机堵塞及齿板磨损快、皮带工作面粘料等问题,论述了在技改实践过程中遇到的难点和采取的方法。同时还介绍了管状皮带机运营过程中出现扭带的判定、原因和调整方法,同时还阐述了防治措施。
In this paper, a case study of the screening, crushing and belt conveyor system of the Dagongshan Nickel Project in Myanmar is introduced. The heavy plate feeder existing in the transportation of crushed and tubular belt conveyors is introduced. Crushing machine jamming and tooth plate wear fast, the belt surface adhesive and other issues, discusses the difficulties encountered in the process of technical innovation and the method taken. At the same time, it also introduced the judgment, reason and adjustment method of twisting band occurred during the operation of tubular belt conveyor. At the same time, the prevention and cure measures were also elaborated.
