煤立磨系统静态选粉机的升级改造措施

Upgrading and reforming measures of static classifier in coal vertical mill system

为了节约资金,满足新建石灰回转窑所用煅烧煤粉性能的要求,将旧有煤粉制备系统煤立磨静态选粉机改造升级为动态选粉机。结果表明,改造后煤立磨的生产能力和产品细度都达到了生产要求,为同类企业通过利旧改造来节约资金投入提供了参考和借鉴。

In order to save money and meet the performance requirements of calcined coal powder used in newly-built lime rotary kiln,the old coal vertical mill static classifier was upgraded to a dynamic classifier.The results show that the production capacity and product fineness of the reformed coal vertical mill can meet the production requirements,which provides a reference for similar enterprises to save the cost through the improvement to the old equipment.
