Abstract: High gradient magnetic separator because of its high magnetic field strength and magnetic field strength changes in range and other factors, has been development and utilization in mineral resources widely, however, the problem of   media jam, low recovery rate and power consumption increased the election cost.SSS new high gradient magnetic separator taking high gradient magnetic separator in multi-graded media, air and water combined unloading ore and energy efficient technologies such as high frequency inverter power supply, effectively solute the media jam, and low recovery problems, more water-saving and electricity-saving than ever before.

Key words: High Gradient Magnetic Separator, Multi-gradient Magnetic Media, Unloading Ore Joint Gas and Water, High Frequency Inverter Type Power Saving
