Iron selection process
来源:本站 发布日期:2019-01-25 人气:44
Iron ore is a worldwide resource. Any economic construction is inseparable from iron ore. It is a technology for industrial development and technological advancement. The distribution of iron ore is relatively wide, with large reserves in all parts of the world, some areas are enriched, some areas are poor, and rivers and lakes contain a large amount of iron ore resources.
Iron ore is a magnetic mineral with different compositions and different magnetic properties. In the iron ore beneficiation, different strength magnetic separators are selected as needed. The main equipment used is: jaw crusher, ball mill, classifier, magnetic separator, dryer, tailings recovery machine, etc. The conditions vary from place to place. In the ore dressing, dry or wet magnetic separators and strong magnetic weak magnetic magnetic separators are selected as needed.
The mined iron ore that is mined is firstly crushed by a jaw crusher. After being crushed to a reasonable fineness, it is evenly fed into the ball mill through a hoist and a feeder, and the ore is ground by a ball mill. The ore fines ground by the ball mill enter the next process: classification. The spiral classifier cleans and classifies the ore mixture by the principle that the specific gravity of the solid particles is different and the rate of precipitation in the liquid is different. The washed and classified mineral mixture separates the magnetic substances in the mixture by magnetic force and mechanical force when passing through the magnetic separator. According to the nature of iron ore, the ore magnetic or weak magnetic separation is carried out. After the dryer is dried, the dried iron ore can be obtained. Generally, the fines after sorting can reach more than 95%.
