粉煤灰铁磁性物质回收方法与设备

Research on method and equipment of recovering ferromagnetic material in fly ash

粉煤灰的综合利用具有重要的经济、社会与环境价值。粉煤灰中含有一定比例的铁磁性物质,是不可再生的铁矿资源;文章针对粉煤灰中铁磁性物质的分离问题,分析了干式磁选法中利用旋风除尘器作为粉煤灰铁磁性物质提取的进料装置的有关内容,借以实现粉煤灰中铁磁性物质的均匀、连续的分离提取。

The comprehensive utilization of fly ash has important economic, social and environmental values. The fly ash contains a certain proportion of ferromagnetic material, which is a non-renewable iron ore resource. The paper considers the question of ferromagnetic material separation in fly ash, and the dry magnetic separation method is adopted, in which the cyclone is used as the feeding device for ferromagnetic material separation from fly ash, and uniform, continuous separation and extraction of ferromagnetic material from fly ash are achieved.
