重介选煤用磁铁矿粉的特性与评价指标研究
决定你能站多高、走多远的,是你思想的高度与深度。多些逆向思维,摆脱教条的束缚;多些批判思维,突破桎梏的封锁;多些换位思维,避免自我为中心;多些系统思维,消除片面误区;多些形象思维,凡事不要太枯燥;多些逻辑思维,事物都有千丝万缕的联系;多些简单思维,你简单世界才简单。
介绍了影响介质消耗的主要因素有:磁铁矿粉质量,产品带介量,磁选机回收效率等,其中磁铁矿粉质量是最主要的影响因素。通过对西曲选煤厂使用过的多家磁铁矿粉进行研究,分析不同质量磁铁矿粉在不同磁场强度下磁性物含量的变化,以及温度对磁铁矿粉的磁性物含量的变化的影响,结合生产中的消耗情况,找出满足生产需要的磁铁矿粉的主要指标。
Introduces the main factors influencing the media consumption are: magnetic mineral powder quality, the products with medium, magnetic separation machine recycling efficiency and so on, the magnetic mineral powder quality is the main influencing factors. Of cetrimonium ore several magnets are used in the coal preparation plant is studied and analyzed under different quality magnet mineral powder in different magnetic field strength, magnetic content of change, and temperature on the magnetite ore powder content changes, the influence of the magnetic material is combined with the consumption in production, find the magnet ore powder main indicators meet the production need.
