S型风扇磨煤机的选型与应用

Selection and Application of S-type Fan Pulverizing Mills

众所周知，影响风扇磨煤机的性能参数主要有：煤质特性、风扇磨的结构特性和运行特性。传统的风扇磨的选型往往是根据煤的可磨度、煤粉细度和原煤水份等修正系数来确定风扇磨的性能参数。实践证阻，该选型方法是不完善的，其通用性较差。采用煤种的试磨方法是风扇磨选型和制粉系统设计较为可靠的方法。本文介绍了根据流动和几何相似原理建立起的Ｓｏ２．３００型风扇磨试验系统，通过对扎赉诺尔和霍林河褐煤的试验验证，把试磨的有关参数移植到大型风扇磨的选型设计中去。为设计院根据煤种合理选择风扇磨及其制粉系统设计提供依据。

It is well-known that the main factors influencing the performance parameters of fan pulverizing mills include coal quality characteristics, fan mill construction features and operating mode. In selecting traditional fan mills correction factors, such as coal grindability, coal fineness and raw coal moisture content, are taken into account to determine the Performance parameters of the fan mills. Practice has shown that such a selection method is not proper and lacks versatility.Trial grinding of coal types constitutes a relatively reliable method for the selection of fan mills and the design of coal pulverizing systems. The present paper deals with a so2.300 fan mill testing system set up on the basis of flow and geometry,similar theory, Through. the experimental verification of Zhalenor and Houlinghe mine ]ignites the relevant parameters of trial grinding have been implanted into a heavy-duty fan mill selection design, thus providing design institutes with a reliable basis for the rational selection of fan mills and related pulverhation systems.
