高压辊磨-干式分级-弱磁选集成系统工艺技术概述

摘要

Summarized the working principle and characteristics of typical high pressure roller mill,grading equipment, powder ore dry magnetic separator. Introduces the structure and possible process of high pressure roller mill-dry classification-low intensity magnetic separation integration system. Characteristics of the technological process and suitable types of iron ore was analyzed. After using high pressure roller mill-dry classification-low intensity magnetic separation integration system in Hami Zhongtian Iron Mine,good sorting index were obtained. High pressure roller mill-dry classification-magnetic separation integration system has advantages of no dressing production water, small occupation, low power consumption, simple process flow,etc.%总结了有代表性的高压辊磨机、分级设备、粉矿干式磁选机的工作原理和特点。介绍了高压辊磨—干式分级—干式弱磁选集成系统的构成及可能的工艺流程，分析了各工艺流程的特点及适合处理的铁矿石类型。高压辊磨—干式分级—弱磁选集成系统在哈密中天铁矿山应用后，取得了较好的选别指标。高压辊磨—干式分级—弱磁选集成系统具有无需选矿生产用水、占地面积小、能耗低、工艺流程简单等优点。
