1、内蒙古科技大学毕业设计说明书摘要按照毕业设计任务书的要求,进行了经山寺铁矿磁选6000t/d的选矿厂设计,产品为铁精矿。经山寺铁矿位于河南省平顶山市境内,为舞钢重要的原料基地。在老师的帮助下,经过一段时间的资料收集,确定了其工艺流程:破碎采用三段一闭路流程,磨矿采用两段全闭路的流程,选别采用三段磁选一段扫选的流程,精矿采用直接过滤的脱水流程。对设计工艺流程进行了工艺指标计算,包括破碎、筛分、磨矿、分级、磁选(包括矿浆流程)和脱水流程。对破碎、筛分、磨矿、分级、磁选及脱水设备进行了选择和计算以及辅助设备的选择和计算,确定了工艺所需的工艺设备。进行了厂房总体布置,并进行了厂房内的设备配置。根
2、据选矿厂的地形条件,进行等高线布置。其中,粗碎、中细碎(筛分)厂房分开布置,粗碎车间、中细碎(筛分)车间平行等高线配置。磨矿和磁选共厂房配置,其中磨矿采用纵向配置,磁选机也采用纵向配置。过滤机与精矿仓配置在精矿厂房内。完成了粗碎、中转站、中细碎(筛分)、磨矿分级磁选、脱水车间的三视图、数质量及矿浆流程图和设备联系图以及建筑物联系图共8张。关键词:选矿厂设计铁矿磁选经山寺89内蒙古科技大学毕业设计说明书AbstractAccordingtotherequestoftheintructionofplantdesignforundergraduated,thedesignofJingshans
