rare earth magnetic separator Introduction

The rare earth magnetic separator raw materials with different magnetic rigidities. It works under the magnetic force and machine force. rare earth magnetic separator are designed to recover ferromagnetic materials. They are available in designs and sizes to provide solutions for all applications. The heart of each separator is the magnetic system with its unique design, which has a proven record of high efficiency. The rare earth magnetic separator are available in cyclic design with process vessel diameters smaller than 3mm.

Working principle of rare earth magnetic separator 

The 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 rare earth magnetic separator again and then the recycle rate can be increased much. The fine ore can pass through the 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.

rare earth magnetic separator features

1). Large angle of magnetic system

2). High BR and high HCB magnetic material

3). High magnet intensity with less than 5% demagnetization

4). Magnet blocks loosing down protection

5). Perfect waterproof ability for the drum 

The production line of rare earth magnetic separator 

rare earth magnetic separator application

rare earth magnetic separator is one kind of efficient equipment for processing fine, feebly magnetic minerals, such as hematite, limonite, wolfram, limonite, and tantalum—niobium, etc. In recent years, it is also more and more applied in purifying quartz, feldspar and nephrite. Its magnetic system is a ring-shape chain closed magnetic circuit with energizing coils made of copper tube and cooled internally by water. Grooved plates made of magnetic conductive stainless steel are used as magnetic matrix.
