Wet iron ore magnetic separator with Ball mill

Drum Magnetic Separator

Application:

Drum magnetic separator select materials with different magnetic rigidities. The machine works by using magnetic force and the machine force. are designed to recover ferromagnetic materials. The separators are available in designs and sizes to provide solutions for all applications.

Detailed Product Description:

The Magnetic Separatoris a ring-shaped chain closed magnetic circuit with energizing coils made of copper tubing and cooled internally by water. Grooved plates made of magnetic conductive stainless steel are used as a magnetic matrix. This separator features a short magnetic circuit, little magnetic flux leakage, high magnetic intensity, low energy consumption, a simple structure and easy maintenance.

The can separate the raw materials with different magnetic rigidities.The machine works under the magnetic force and machine force.Our Magnetic Separators are designed to recover ferromagnetic materials. The separators are availablein designs and sizes to provide solutions for all applications. The heartof each separator is the magnetic system with its unique design, which has aproven record of high efficiency. The Magnetic Separators are available in cyclic design with process vessel diameters from 220 mm to 3,050 mm. Magnetic Separator is one kind of efficient equipment for processing fine, feebly magnetic minerals, such as hematite, limonite, wolfram, ilmenite, and tantalum-niobium, etc. In recent years, it is also more and more applied in purifying quartz, feldspar and nephline. 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. It possesses the following advantages: short magnetic circuit, little magnetic flux leakage, high magnetic intensity, low energy consumption, fine beneficiating results, simple structure and easy to maintain. They have been found widely used in more than 20 mineral processing plants of China.The heart of each separator is the magnetic system. With a unique design it has a proven record of high efficiency. Available in a circular design with process vessel diameters smaller than 3mm, this magnetic separator is an efficient piece of equipment for processing fine magnetic minerals, such as hematite, limonite, wolfram, ilmenite and tantalum-niobium. Recently, this equipment has also been more and more frequently used in purifying quartz, feldspar and nepheline. Wet-type permanent magnetic separator mainly consists of such four parts as cylinder, magnetic system, cell and transmission parts. Cylinder is made of 2-3mm welded and bent stainless steel and the terminal cover is forged aluminum plate which is connected with stainless bolts. The motor drives the cylinder to go round and round through decelerated machine. The magnetic system is open and put in the cylinder. The magnetic piece is installed on the bottom plate with stainless bolt, the axis of magnetic yoke spreads out of cylinder, and there is cranks which are fixed on the end of axis. The angle of magnetic system can be adjusted by pulling the crank, and be fixed with push rod. The working area of cell is made of stainless steel plate, and the other parts of frame and cell adopt common welded steel.

Working Theory of Magnetic Separator:

The mineral slurry flows into the cell through box feeder, the mineral particle is loose under the function of water flow of feeder water pipe when they flow into the cell. Affected by magnetic field, the magnetic particle swarm together and form magnetic cluster or chain. With the magnetism of mineral slurry, the magnetic cluster or chain moves toward the magnetic pole, and is absorbed to the cylinder. Because of the polarity of magnetic pole, the revolving directions alternate constantly, and remain fixed when it is working. When the magnetic cluster and chain go round and round along with the cylinder, the mingled gangue and other non-magnetic ore fall down due to the mixing phenomena produced by alternation of magnetic poles, and it is concentrate that is absorbed to the cylinder surface. The concentrate moves to the end of magnetic system where the magnetism is weakest along with the revolving cylinder, and is discharged into concentrate tank by the current ejected by the discharging-ore pipe. The non-magnetic or weak magnetic remained are discharged along with the mineral slurry, and they are gangue.

Performance and Features of Magnetic Separator:

The magnetic system ofmagnetic separatorintegrates good-quality iron-oxide body materials with rare earth magnetic steel; the average magnetic induction intensity of cylinder surface is 100-600mT. According to the needs of customers, the magnetic separator can be co-current, half-countercurrent, countercurrent, and so on. The magnetic separator has the advantages of simple structure, big processing volume, convenient operation and easy maintenance, etc.

Purpose of Magnetic Separator:

The magnetic separator is applicable for wet mineral separation of such materials as magnetite, pyrrhotine, roasted ore and ilmenite, etc. and it is also applicable for iron removal working of such materials as coal, nonmetal and building materials, etc.
