1、 中文题目：选煤厂用磁选机总体结构设计 外文题目：THE DESIGN OF THE OVERALL STRUCTURE OF MACHINE WITH MAGNETIC COAL PREPARATION PLANT 摘要 磁选机是在产业界使用最广泛的、通用性高的机种之一，使用于再利用粉状粒体中的 除去铁粉等，磁选机广泛用于资源回收，木材业、矿业、窑业、化学、食品等其他工场。 选煤厂用磁选机的目的是除去洗煤后的泥浆中所含的大量磁铁粉，使有用物质从泥浆 中分离，并且得到重复利用。可见，磁选机对选煤厂回收再利用磁铁粉有着十分重要的作 用，降低了选煤厂的生产成本而且节约了资源。 磁选机是一种产生强大

2、磁场吸引力的设备，它能除将混杂在非磁性物料中的铁磁性杂 质分离，以节省成本，节约资源。近年来，为满足工业生产的多种需要，研制开发出了大 量的新型磁选机。 本文在已知的磁选机的基本结构的基础上，进行了选煤厂用磁选机的总体结构设计、 重要部件的分析设计计算及校核、传动方案的分析和设计计算；进行了驱动装置中的减速 器、电动机、弹性联轴器等的设计选用；同时对磁选机其他附件进行进一步的设计计算。 说明书中的部分设计计算过程和结果对本设计方案的确定提供了充足的理论计算数据。 关键词：磁选机；选煤厂；结构；传动方案；轴 Abstract Magnetic separator is the most wide
