喷煤车间五系列中速磨系统制粉能力分析

Analysis on the Powder-making Capacity of the 5th Medium-speed Grinding System in the Pulverized Coal Workshop

分析影响五系列中速磨系统制粉能力的因素,确定中速磨旋转叶轮喷嘴上部截流环安装位置不当等影响因素,通过改变喷嘴环上部截流环位置,提高了磨盘边缘的风速与风量,改变了导向。降低废料排出量,实现制粉能力提高。

The paper analyses the influence factors of powder - making capacity of the 5th medium - speed grinding system, specifies the instaUation location of the stopping ring above the rotary vane nozzle is incorrect. The air speed and the air quantity of the grinding- disk＇s edge increase by changing the location,the guide changes,the discharge of the waste decreases,the capacity of powder - making is improved.
