Abstract: A vertical ring high gradient magnetic separator comprises an exciting winding coil and a coil casing, wherein the winding coil is immerged in coolant in the coil casing, the winding coil is of a multi-layer structure, and an insulating member is provided between each layer or a plurality of layers of the winding coil to form gaps through which the coolant passes. The winding coil of the vertical ring high gradient magnetic separator has a rapid heat dissipation capability in the coolant, which can ensure the winding coil maintaining a lower temperature during operation, thereby obtaining a higher magnetic field strength.

Abstract: This is an evaporative cooling electromagnetic separator. It includes a shell and an iron core installed inside the shell. A set of wire coil is winded around the iron core. Inside the shell is cooling medium, which is evaporative cooling medium or mixture of evaporative cooling medium and transformer oil. A condenser is installed on the top of the shell. On one side of the condenser is a steam gathering pipe, which joints with the shell from its top, and on the other side of the condenser is a liquid gathering pipe, which connects with the shell from its flank. The present invention will help to enhance the security, reliability and cooling capability of the electromagnetic separator, and possesses broad application perspective.
