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.
