摘要
简述高庄煤矿选煤厂技改前生产系统存在的主要问题,重点介绍用400余万元投资增设小时处理能力214 t原料煤的无压给料三产品重介旋流器生产系统技改工程的工艺流程,以及改造后在跳汰与重介并联运行中精煤指标的调整所取得的效益。
This paper introduces the problems of production system before technical innovation in Gaozhuang Preparation Plant;the technical process of technical innovation project of production system of pressureless feed three products dense-medium cyclone that consumed 4 millions yuan and processing power is 214 ton feed coal per hour,and the benefit achieved by adjusting clean coal index in jigging and dense-medium separation paralleled connection after technical innovation.
