Open the CIPO recordAbstract From the Canadian patent
A high-intensity-field magnetic drum separator having a stationary, open magnet system in an interior thereof. In addition to low capacity, known high-intensity-field magnetic drum separators are also unsuitable for separating ores in which the size of some of the grains is far below 100 µm. The present invention provides an economically acceptable uncomplicated, type of separator of considerably greater power and range than known similar separators, making it possible to separate even very weakly magnetic substances. The magnetic drum separator according to the present invention has a magnet system consisting of an arrangement of super-conductive conductors.
