利用数值模拟法对中速磨煤机内的一次风流场进行了模拟。
The flow fields in the HP medium speed mill were simulated by employing the numerical simulation meth-od.
介绍了根据几何和流动相似原理建立起的ZQM 41型试验中速磨煤机的试验系统。
Introduced the test system of ZQM 41 model test medium speed coal grinder which based on the geometry and flow similarity principle.
由于发电用煤种类多、杂质含量偏高，可磨性较差，造成中速磨煤机磨辊耐磨寿命缩短。
Because coal for power generation varies widely and has high foreign substance content and low grindability, the life time of the rollers in medium speed pulverizer is shortened.
而我国火电机组采用中速磨煤机和风扇磨煤机的历史不长，对其制粉系统的运行特性建立的仿真模型与实际运行工况还存在不小的差距。
But it has not been long to use the middle-speed mill and fan mill in thermoelectric generator units in China, and there are still big gaps between the simulation model and the actual behavior.
