1) Constant magnetic field vertical roller mill. Using a permanent magnet material and a direct current electromagnet, a solenoid, or the like as a magnetic source, the magnitude and direction of the magnetic field strength do not change with time.

2) Alternating magnetic field vertical roller mill. An electromagnet that is connected to an alternating current is used as a magnetic source. The magnitude and direction of the magnetic field strength changes over time.

3) Pulsating magnetic field vertical roller mill. An electromagnet that simultaneously transmits direct current and alternating current is used as a magnetic source. The magnitude of the magnetic field varies with time, but the direction does not change. And pulse
