<p>A vertical ring high gradient magnetic separator, including an excitation winding coil (11) and a coil housing (12), wherein the winding coil (11) is submerged in the cooling liquid of the coil housing (12), the winding coil (11) is of a multi-layer structure, and a gap through which the cooling liquid can pass is formed among each layer or a plurality of layers of the winding coil (11). The winding coil (11) of the vertical ring high gradient magnetic separator has rapid heat dissipation capability in the cooling liquid and can ensure that the winding coil (11) keeps a relatively low temperature during operation so as to obtain a relatively high magnetic field strength.</p>
