文档介绍: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。

Abstract
According to the request of the intruction of plant design for undergraduated, the design of Jingshansi iron Mine ic separation with the capacity of 6000t/d, and the products is iron concentrate.
The Jingshansi iron Mine is located in Pingdingshan City in Henan provience, an important raw material for the the help of the teachers and the collection of data, The work institutions of each workshop were determined, The process of crushing is three sections with one close circuit, the grinding process is two sections with all closed circuit, Sorting by three-stage ic separation process of a sweeping election,the concentrates is direct filtration dehydration process.
Technological parameters of crushing ,screening, grinding , classificatio- n ,ic separation (include the circuit of pulp)and dewatering puted, respectively. Then the technological parameters of equipments and the auxiliary equipments pared ,and the optimal equipments were determined.
The general arrangement of concentrator plant and the allocation of equipments in diferent workshop were presented. According to the topography of plant site, plants were arranged along the contour line . The workshops of coarse crushing, middle and fine crushing (screening) were aloted independent. Arrangment with parallel contour line of coarse crushing workshop、middle and fine crushing ( screening) workshops were used. Grinding and ic separation of plant configuration, the grinding used vertical configuration, ic separator i
