1 总则
随着水泥生产设备向大型化发展,特别是球磨机体积越来越大、生产能力越来越高,国内水泥生产厂家常用的球磨机一般有以下三种类型:
1 边缘传动、中心卸料,由中空轴支承磨筒体;
2 中心传动、中心卸料,由中空轴支承磨筒体;
3 中心传动、中心卸料,由滑履轴承支承磨筒体。
4 第一种类型的球磨机造价低,结构简单,不需要大型的减速机,但存在大小齿轮易磨损,寿命短的缺陷,在使用过程中,随着大小齿轮的磨损加剧,运行状态越来越差,一般情况下,该类型适用于中小型球磨机。
5 第二种类型的球磨机是国内前几年使用最多的球磨机,它克服了边缘传动球磨机的缺点,提高了使用寿命,但是,在球磨机大型化以后,球磨机的自重太大,若用中心轴支承、中空轴传动时,对球磨机的端盖和中空轴制造增加了难度.
6 第三种用滑履轴承支承的球磨机,该类型球磨机有如下优点:
1)滑动环焊接在球磨机筒体上,减轻了磨筒体端盖的制造难度;
2)不用中空轴支承磨筒体,缩短了磨机的整个长度;
3)支承间距较近,筒体的机械应力较小,可减少筒体钢板的厚度。
为了规范水泥生产线球磨机的施工,加快推广和应用球磨机的先进安装技术,确保球磨机安装质量和安全,降低施工成本,制定本标准。
球磨机的安装除应符合本标准、GB50231-2009 《机械设备安装工程施工及验收通用规范》、GB50276-2010《破碎、粉磨设备安装工程施工及验收规范》以及JCJ03-1990《水泥机械设备安装工程施工及验收规范》外,尚应符合国家现行有关标准的规定。
