球磨机控制系统的设计

球磨机是火电厂的一种重要设备,它将原煤破碎並研成粉末,为了生产的安全性和稳定性,需要有温度,压力与差压控制系统,由于系统的耦合影响,系统长期处手操状态,甚至被取消。本文介绍一种控制方案,该方案成功地应用于球磨机控制系统,经长期满负荷使用,证明具有显著的经济效益。

A Design of COntrol System for the Ball Mills

Being an important equipment in a fire powerplant, the ball mill is capable of breaking natural coals and milling them into coal powders. For the security and stability of production, a control system is needed for controlling over temperature, pressure and differential pressure. Owing to the coupling effect of systems, these systems are oporated manually and are lain aside over a long period of time. This paper presents a control scheme applicable to the control system of ball mill. It was suocessfully used under long time full load and proved to be a control scheme with significant economic benefit.
