针对尖山铁矿铁精矿粒度存在的问题，通过强化内部管理，积极制定有力措施，保证了铁精矿粒度－325目≥70％、－200目≥92％、＋100目≤0．3％，为铁精矿长距离管道输送系统的正常运行创造了良好条件。
In view of the existing problems of the iron ore concentrate size in Jianshan Iron Mine, effective measures have been actively worked out by strengthening internal management to ensure the iron ore concentrate size of -325 mesh ≥70%, - 200 mesh ≥92%, +100 mesh ≤0.3% It has created good conditions for the normal operation of iron ore long distance pipeline transportation system.
