我矿五家子选厂原设计采用干式自磨机,自1977年试车投产以来,暴露出不少问题。如磨矿效率低、粒度粗、磨机常被“糊死”、风路易堵塞、管路严重磨损、操作复杂、管理困难及粉尘大等。针对此问题,我们于1978年进行了分析研究并外出考查,决定将干式自磨机改为湿式自磨机。同年年底改成一台,1979年又改造 My mine five sub-plant original design using dry self-grinding machine, put into trial operation since 1977, exposed a lot of problems. Such as low efficiency of grinding, coarse particle size, the mill is often “muddle”, easy to plug the air duct, pipe serious wear and tear, complicated operation, management difficulties and dust and so on. In response to this problem, we conducted an analytical study in 1978 and went out to test, decided to dry from the mill to wet self-mill. The same year into a Taiwan at the end of 1979 and transformation
