现阶段我国磨矿设备的研究进展及发展方向

Research Progress and Development Direction of Grinding Equipments in China at Present Stage

传统格子型球磨机,排矿速度快,能减少矿物的过粉碎,但对格子板要求严格,且检修不方便;而溢流型球磨机,生产能力较低,易发生粉碎现象。针对传统磨机的不足,从筒体形状、排矿方式和传动部件等方面介绍了目前采用的一些新型设备。立式搅拌磨可以提高破碎的精准度,有利于细磨和选择性磨矿;高效节能筒辊磨节约能量,运转可靠;周边排料磨能较少矿物的过粉碎率;静动压轴承球磨机和中心传动球磨机,传动比大,噪音小;离心自磨机,能处理较粗物料,且适用于细磨。并在此基础上对磨矿设备的发展趋势与方向进行了展望。

The traditional lattice type ball mill has the characteristics of good discharge speed, which can reduce the mineral crush, but it is strict to select the lattice board and not convenient to repair, while the production capacity of the overflow type ball mill is low and the phenomenon of crushing easily happens. According to the deficiency of the traditional grinding machine, some new type equipments were introduced from these aspects of cylinder shape, dis- charge methods and transmission parts. The vertical agitate mill can improve the precision of crushing in favor of the fine grinding and the selective grinding, the high-efficiency and energy-saving cylinder mill can save energy and op- crate reliably, the peripheral discharge grinding can reduce the over crushing rate of minerals, the static and dynam- ic pressure bearing of ball mill and center driving ball mill has the characteristics with large transmission ratio and small noise and the centrifugal mill can deal with the coarse material which is suitable for the fine grinding. On the basis, the development trend and direction of the grinding equipments are prospected.
