permanent rare earth magnetic separator Introduction

The permanent rare earth magnetic separator is generally a low cost method of recovery, unless high intensity separators are required. The electro-magnetic high intensity separators that produce 20,000 gauss; the rare earth permanent rare earth magnetic separator is relatively inexpensive and can produce magnetic fields around 6,000 gauss. To different kinds of mineral ores, the application of permanent rare earth magnetic separator is quite different.

Working principle of permanent rare earth magnetic separator

The permanent rare earth magnetic separator is mainly composed of cylinder, magneti system, trough and transmission part.After the ore slurry running into the trough through ore box an effected by the feeding ore water pipe, the ore particles can enter into the ore feeding area in trough. The magnetic ore particles can form ‘magnet group’ or ‘magnet chain’ by magnetic field’s affect. All the ‘magnet group’ or ‘magnet chain’ moves to magnetic poles because of magnetic force in the ore slurry and then they can be attached to the cylinder. Since the polarity of magnetic poles are arrayed alternately and fixed tightly when working, when ‘magnet group’ or ‘magnet chain’ turning with the cylinder, the non magnetic materials, such as matrix which are mixed with ‘magnet group’ or ‘magnet chain’ will drop down during the rolling process. Eventually, the ‘magnet group’ or ‘magnet chain’ attached to the cylinder surface are fine ore. When the fine ore turn to the weakest place of magnetic system in the cylinder, it will be pushed to the fine ore trough by the water coming from unloadore pipe. Non magnetic or weak magnetic ore are left in the ore slurry and then discharged out of the trough, these ore are the gangue. Some magnetic ore can be recycled by putting the gangue in permanent rare earth magnetic separator again and then the recycle rate can be increased much. The fine ore can pass through the permanent rare earth magnetic separator again and the matrix which mixing with the fine ore can be wiped out to upgrade the purity of fine ore.

The production line of  permanent rare earth magnetic separator

permanent rare earth magnetic separator application

permanent rare earth magnetic separator is suitable for the wet magnetic separation of the materials whose granularity is below 3mm such as magnetite, pyrrhotite, calcined ore and ilmenite and can also be used for emoving iron from the materials such as coal, nonmetal ore and building material. permanent rare earth magnetic separator can be divided into three types according to trough’s different structure; they are downstream type, semi-reflux type and reflux-type.
