The invention provides a forced-oil-cooling vertical rotating ring induction type wet process pulse intensity magnetic separator which mainly comprises an excitation system, a separation system, a pulse system, a collecting system, a supporting system, a drive system and a protection system. The excitation system provides a working magnetic field. The separation system achieves a function of continuously separating concentrates and tailings. The pulse system provides a pulse effect for ore pulp to disperse ore in the ore pulp. The collecting system achieves the functions of feeding, flushing, concentrate and tailing collecting and liquid level observing and adjusting. The supporting system is fixedly connected with a field foundation and supports the forced-oil-cooling vertical rotating ring induction type wet process pulse intensity magnetic separator. The drive system provides power for a rotating ring and the pulse of the forced-oil-cooling vertical rotating ring induction type wet process pulse intensity magnetic separator. The protection system achieves the function of protecting personnel and equipment safety. According to the forced-oil-cooling vertical rotating ring induction type wet process pulse intensity magnetic separator, all the parts are organically combined, and good indexes can be achieved on occasions of iron ore separation, nonmetal impurity removing, colored ore separation, rare earth ore separation and the like.
