高频谐波磁场磁选机的研究及应用

针对铁矿石磁选过程中出现的磁团聚夹杂脉石严重的现象,研制出了一种新型高频谐波磁场磁选机,此类设备利用高频交变磁场对磁性矿物产生的高频磁扰动来打破磁团聚,进而提高分选精度。本文重点介绍此类设备的关键技术及发展历程,以及在铁矿石磨前干式预选,磨后精选及冶金粉材提纯除杂等领域的应用进展,并对相关设备未来发展方向作了展望。

Analysis and Simulation of a Typical Opening Magnetic System

In view of the serious phenomenon of magnetic agglomeration and inclusion of gangue in the process of magnetic separation of iron ore in China, BGRIMM has developed a new type of high-frequency harmonic magnetic field magnetic separator. Such equipment uses high-frequency alternating magnetic fields to generate magnetic minerals. High frequency magnetic disturbance to break magnetic agglomeration, Then improve the sorting accuracy. This paper mainly introduces the technical development process of this kind of equipment, the key technologies and the application progress of iron ore pre-grinding pre-dry pr-selection, post-grinding selection and metallurgical powder purification, etc..The future development direction of the related equipment is also foretasted.
