SBM wet magnetic separator
SBM’s s wet magnetic separators are available in several sizes and tank designs in order to meet the varying requirements of the iron ore processing industry. SBM has always worked closely with the iron ore industries, which has led to some unique features in the magnetic separators that have resulted in outstanding operating performance.
Magnetic Separation Theory
The magnetic separation process is complex in many respects due to the varying magnetic susceptibility of the different ores, the amount of middlings, and the particle size distribution of the processed ore.
The magnetic force acting on a specific particle is dependent upon these factors as well as other properties such as magnetic flux and magnetic field gradient, which are created by the magnetic system in the separator.
The product of field time gradient, also called the magnetic force index, varies between different magnetic system designs and is a factor when selecting the most suitable magnetic system for a particular process.
As in all applications, the magnetic force is competing with other forces such as gravity and hydraulic drag; therefore, the feed volume and tonnage must be balanced to obtain a suitable level of performance.
Generally speaking, the smaller the particle size that is being processed results in a lower feed capacity of the equipment. By selecting a higher magnetic field strength (magnetic flux) the feed capacity can be increased considerably, in many cases the recovery of the fines increases significantly with the field strength.
