目前国产中速磨煤机的制造技术是引进、吸收、改造国外各相关系列中速磨煤机制造技术的结果，因而流派很多，各具特色。通过对国产HP、ZGM、MPS、MPS-HP-Ⅱ型4种中速磨煤机引进过程介绍和结构、运行效果的分析，指出了有利于磨煤机运行和维修的结构形式。在此基础上，提出了融合各型中速磨煤机优势结构的方案，为国产磨煤机的选型和发展提供参考。

At present, the manufacturing technology of domestic medium speed coal mill(MPCM) has different features by introducing, absorbing and reconstructing the overseas manufacturing technology for related series MPCM. The introducing processes for domestic HP, ZGM, MPS, MPS-HP-Ⅱ MPCM are introduced, and the corresponding structure and operation effect analyzed. Based on this, the structure beneficial to operation and maintenance of the mill is pointed out. Furthermore, an optimal structure by fusing the advantages of each MPCM is puts forward, providing references for the selection and development of domestic coal mill.
