首钢矿山公司大石河选矿厂,采用矿山公司技术交流站组织研制的螺纹密封取代8PSJ型胶泵高压水封,在尾矿砂泵站试验成功,获得了可喜经济效果。本文拟以生产现状、试验考查以及结论等三部分评述。 (一) 生产现状大石河选厂坚持老厂挖潜,生产规模不断扩大,目前已由原设计7个生产系列扩建到11个生产系列,矿石处理能力由原设计的400(万吨/年)增至650(万吨/年)。排尾量为
Shisco Steel Corporation Dashihe beneficiation plant, using the company’s technology exchange station organized by the mine thread seal instead of 8PSJ-type high-pressure pump seal, the tailings sand pumping station test was successful, gratifying economic benefits. This article intends to review the production status quo, test and conclusion and other three parts. (I) Status of Production Dashihe Dressing Plant Insist on tapping the potential of its old factory and expanding its production scale. At present, it has expanded from 7 production lines to 11 production lines. The ore processing capacity is increased from 400 (10,000 tons / year) originally designed To 650 (million tons / year).
