摘要：当今的矿粉市场竞争激烈，利润下滑明显，矿粉企业急需提升生产管理，降低生产成本。作为一名生产管理人员，以本公司目前遇到的最棘手的问题为例，当磨机因设备故障跳停时，需要在二分钟内将磨机出口温度控制在120℃以下，才能保证3个主体设备不会连锁跳停，当前现有的降温阀门基本做不到，如想快速降温就需人员现场手动打开选粉机检修门，一般人员从休息室走到选粉机检修门大约需要5分钟，在时间上面就来不及;因此公司对选粉机的检修门进行了自动化改造，达到了预期的效果，缩短了开机时间，提高运转率和降低了人员的劳动强度。

Abstract： In today's mineral powder market， competition is fierce and profits are declining. Mineral powder companies urgently need to improve production management and reduce production costs. As a production manager， take the most difficult problem currently encountered by our company as an example. When the mill is tripped due to equipment failure， it is necessary to control the outlet temperature of the mill below 120°C within two minutes to ensure 3 The main equipment will not jump and stop in a chain， and the current cooling valve is basically unable to do it. If you want to cool down quickly， you need to manually open the powder separator inspection door on site. It takes about ordinary personnel to walk from the lounge to the powder separator inspection door. 5 minutes is too late for time; therefore， the company has automated the overhaul door of the powder separator， which achieved the expected effect， shortened the start-up time， increased the operation rate and reduced the labor intensity of the personnel.

武新公司是一家绿色环保企业，生产的产品原材料为粒化高炉矿渣，生产的过程不掺加任何添加剂，生产的主要产品为矿粉和超细粉。目前公司现有5台立磨生产线和两台超细粉生产线，立磨生产线最主要粉磨设备采用了德国菜歇公司生产的LM46.2+2S立式磨机，该磨机它能够高效综合地完成物料的粉磨、烘干、选粉和输送，自动化控制程度高，集多功能于一体，在国际得到广泛的推广和应用。由于当初在工艺设计上，只在热风炉及热风管道上面设计了三个降温阀（分别为冷风阀、入磨冷风阀、循环风阀），没有在磨机本体上安装降温的阀门，导致当磨机故障停……
