Magnetic separation is kaolin, potassium albinite and quartz and other non-metallic ore iron removal is the most widely used and the most effective method, widely used magnetic separation equipment mainly dry PTMS Electromagnetic Separator.
Dry PTMS Electromagnetic Separator has the advantages of simple structure, low operating cost, less investment and energy saving and environmental protection. The dry magnetic separation technology is especially suitable for the cold areas with abundant resources but serious water shortage in the west and north of China.
According to the different magnetic induction intensity, dry magnetic separator can be divided into: dry weak magnetic field PTMS Electromagnetic Separator, dry magnetic field in the PTMS Electromagnetic Separator, dry strong magnetic field PTMS Electromagnetic Separator, dry high gradient PTMS Electromagnetic Separator.
Dry strong magnetic field PTMS Electromagnetic Separator is mainly used for the separation of coarse minerals, can be divided into electromagnetic magnetic system and permanent magnetic system 2. Such as dry electromagnetic induction roll strong PTMS Electromagnetic Separator is suitable for fine non-ferrous metal minerals in addition to iron and non-metallic ore purification. Permanent magnet roller type PTMS Electromagnetic Separator is developed along with the development of rare earth permanent magnet materials. It has higher magnetic force, smaller quality and size, and lower technical cost than electromagnetic induction roller magnetic separator. Coarse-grained permanent magnet roller type strong PTMS Electromagnetic Separator is suitable for coarse-grained tailings and non-metallic ore purification.
Dry high gradient PTMS Electromagnetic Separator is suitable for non-metallic ore dry iron removal, such as under laboratory conditions using dry vibration high gradient PTMS Electromagnetic Separator 1 separation to obtain quartz concentrate Fe2O3 grade is only 0.04% of good indicators. The successful development of dry vibration high gradient PTMS Electromagnetic Separator has positive significance to improve the comprehensive level of non-metallic mineral processing and comprehensive economic benefits, and can meet the demand of iron removal in most medium and small non-metallic mines. Dry vibrating high gradient magnetic separator, the present study of dry magnetic separation equipment, do not take the other performance parameters of the magnetic material influence on magnetic field characteristics, separation technology is more extensive in the process of production, cannot achieve fine separation, metal loss rate is high, should be required to separate the material combined with the characteristics of the magnetic field characteristics and improve equipment adaptability. Micro-fine particle dry separation equipment will be an important development direction in the future, and it is the key to high efficiency and energy saving of dry magnetic separation equipment.
