论述了粉碎机构学是由机构学衍生而来，与相关粉碎理论结合，应用于物料粉碎领域里的一门工程基础学科。随着矿产资源高效节能开发和诸多领域的粉碎作业增多，对粉碎机械的使用要求不断发生变化，粉碎机构学越来越成为重要的基础理论，并逐渐形成新的学科分支。随着现代机械设计理论的发展，粉碎机构学理论也将在实践中不断得到丰富、发展和完善。

Crushing mechanism is an engineering basic subject which is derived from mechanism, combined with interrelated crushing theory, and applied in crushing field. With the high efficiency and energy-saving development of mineral resources, and the change to crushing machine's application，crushing mechanism is becoming a more and more important subject, and forming a new mechanism branch. The modem development of crushing mechanism will accelerate theory's development of crushing mechanism in practice.
