文档介绍：摘要
按照毕业设计任务书的要求,进行了洪范池铁矿年处理40万吨选矿厂设计,产品为铁精矿。
在老师带领下,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:破碎采用三端一闭路流程,磨矿采用阶段磨矿流程,磁选用阶段磁选流程。
对设计工艺流程进行了工艺指标计算,包括破碎、筛分、磨矿、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。根据选厂房的地形条件,沿山坡地布置,其中,粗碎、中细碎、筛分厂房共厂房布置。磨矿磁选共厂房配置,其中磨矿采用纵向配置,磁选机采用横向配置。过滤机与精矿仓配置在厂房内。完成了粗碎、中细碎、筛分、磨选、脱水车间平断面图、数质量及矿浆流程图和设备联系图等。

Abstract
According to the requirements of graduation design, the HongFanChi 400,000 tons of iron ore processing, product design for the concentrator iron concentrate.
In the teacher led to collect information on the basis of design. Various workshop working system, the design process of the selection and argumentation, the design process, namely: the broken ends by grinding process, a circuit using a ic circuit flow, and by filtration dehydration concentrate.
The design process of the calculation process, including the crushing, screening, grinding, ic separation (including pulp flow) and dehydration process. For crushing, screening, grinding, classification, ic separation and dewatering equipment and the choice is needed, the process of process equipment.
The plant layout, and the workshop equipment configuration. According to the topography condition, choose workshop layout, including the hillside, crushing, screening of finely, factory workshop layout. The grinding of plant configuration, including ic grinding adopts vertical configuration, the flotation machine adopts horizontal configuration. Filters and concentrate on plant configuration storehouse. Finish the crushing, screening, finely, float, dehydration workshop section, the quality and the number of flat pulp flow and equipment including contact.
