1、摘要按照毕业设计任务书的要求，进行了8000t/d磁铁矿选矿厂设计，产品为铁精矿。在包钢巴润矿业有限公司进行了为期三周毕业实习，收集相关设计资料的基础上。确定了各车间的工作制度，对设计工艺流程进行了选择和论证，确定了设计的工艺流程，即：破碎采用三段一闭路流程，磨矿采用两段全闭路流程，并采用阶段磁选，精矿用一段脱水。对设计工艺流程进行了工艺指标计算，包括破碎、筛分、磨矿、磁选和脱水流程。对破碎、筛分、磨矿、分级、磁选及脱水设备进行了选择计算和方案比较，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
2、备配置。根据选厂房的地形条件，沿山坡地布置，其中，粗碎、中碎、细碎、筛分厂房分开布置，磨矿和磁选共厂房配置。过滤机与精矿仓配置在厂房内。完成了粗碎、中碎、细碎、筛分、磨磁、脱水车间平断面图、数质量及矿浆流程图和设备联系图共9张。关键词：选矿厂设计；磁铁矿；磁选8000t/dMagnetiteConcentratorDesignAbstractAccordingtotherequestoftheintructionofplantdesignforundergraduated,thedesignof8,000t/dm
