subject: Feature And Application Of Dry Magnetic Separator [print this page] It is a common sense that the magnetic separator is useful equipment in mining machinery, just like impact crusher, ball mill, rotary kiln and so on.
Features of the dry Magnetic separator
1. This dry Magnetic separator is suitable for processing various bulk materials and will not blocked for its compact structure
2. Low power
3. Also has disaggregating function for sticky and poor-fluidity powders
4. Stainless steel machine and full-closed operation enable an easy clean
5. This high gradient magnetic separator has optimized magnetic circuit, which offers high intensity magnetic field for better separating effect
6. Dry Magnetic Separator working under high temperature
The Performance of Dry Magnetic Separator
The magnetic separator has the performance of simple structure, big processing volume, convenient operation and easy maintenance, etc.
Application of Dry Magnetic Separator
Permanent cylindrical dry powder magnetic separator is available from one cylinder to four cylinders. It is a magnetic separator that is used to continuously remove iron from dry powder materials. This magnetic separator adopts ND-Fe-B as the magnetic source and is of strong magnetic force, strong suction, high efficiency, free maintenance, good energy efficiency, safe operation, and more characteristics. The charging speed is controllable for different granular requirements.
Working Theory of Dry 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.
