Abstract

The invention provides a manufacture process and an application technical process of a high-gradient magnetic separating machine with an ultrastrong magnetic field. Set magnetic separating magnet materials comprise ferrite, alnico, SmFeN and a rare earth permanent magnet material. A magnetic separating chamber is made of non-magnet-conducting materials, a slurry outlet and a slurry inlet are respectively arranged on the upper part and the lower part of the magnetic separating chamber, and magnetic separating media put in the separating chamber are steel wool. An emission-reducing and energy-saving ball mill saves energy and reduces the emission of exhaust gas. Multiple times of fine separation are adopted in the technical process for improving iron content. After tailings are ground by using the ball mill to reduce the iron content in the tailings, the tailings enter a sorting machine, and a high-gradient magnetic separating technical process of stainless steel wool is adopted for treating waste water. The magnetic separation and mine sewage treatment technical indexes of the process provided by the invention reach an advanced level.

Description

Technical field: [0001] The invention relates to a magnetic separation equipment pole preparation process for magnetic separation and its application technology, in particular to an energy-saving emission reduction ultra-strong magnetic field high-gradient magnetic separation equipment technology and its application technology in a magnetic separator. Background technique: [0002] The new theory and application technology of strong magnetic field and high gradient magnetic separation is a new high-tech technology.
