Problems solved by technology
At present, water washing ball milling process and rod milling process are widely used in China to recover ferrite, but the fine powder grade of the recovered products is 40%-45%, the tailings grade is 20%-25%, and the product quality is low. " The phenomenon of "running tail" is obvious; and the commonly used magnetic separation devices in China are not equipped with environmental protection devices, and the secondary dust in the magnetic separation process brings greater environmental pollution and environmental protection risks

Description
technical field [0001] The invention belongs to the technical field of metallurgical steel slag treatment, and in particular relates to a magnetic separation device for selecting iron and steel slag from iron-containing materials. Background technique [0002] At present, the main method to realize the resource utilization of iron and steel slag is crushing and magnetic separation, so as to recover and reuse the magnetic ferrite in the iron and steel slag. At present, water washing ball milling process and rod milling process are widely used in China to recover ferrite, but the fine powder grade of the recovered products is 40%-45%, the tailings grade is 20%-25%, and the product quality is low. " The phenomenon of "running tail" is obvious; and the commonly used magnetic separation devices in China are not equipped with environmental protection devices, and the secondary dust in the magnetic separation process brings greater environmental pollution and environmental protecti...
