摘　　要：MPS型磨煤机在我国电力系统中越来越广泛地应用，但加载力恒定的传统磨辊加载方式存在着影响磨煤机运行经济性和可靠性的问题，本文详细介绍了磨辊加载力随给煤量变化而变化的磨辊自动加载系统的构成及原理，并对该系统进行了全面的分析，为国内MPS磨煤机制造厂家设计和电厂改造加载系统提供参考。MPS pulverizers have been more and more widely used in power system of China, but conventional roll wheel spring pressure system which is invariant has an impact on reliability and economics of pulverizer operation. This paper introduces the principle and structure of roll wheel automatic spring pressure adjusting system by which roll wheel spring pressure can change with coal feed. This system is fully analyzed and given for the design of MPS pulverizer makers and technical modification of power plant as reference.
