Electromagnetic Filter Usage in Ceramic Sector
Iron minerals causes major quality problems for the ceramics industry . These minerals can be mixed naturally in the ore or into raw materials made by during processing. Permanent magnetic bar separators and electromagnetic filters are used for separation iron minerals from ceramic raw materials. Electromagnetic filters are preferred mostly because of the adjustable electromagnetic field intensity, higher magnetic field strength, controllability and automatic cleaning.
In the sector, magnetic intensity could enough between 5,000 to 6,500 gauss, for higher quality demands needed to be exceeding to 1.0 Tesla.
The matrix in the Electromagnetic Filters can be adjusted according to the grain size and the number of stages is optimized with the coil as desired. Depending on the amount of metal empurites in the raw material, the separation time and washing times can be adjusted. While the separation time can be short for dirty raw materials conditions, the separation time can be longer for cleaner raw materials as the matrix will work more easily. The separation circuit is controlled via PLC with fully automatic valves and electromagnetic group that is automatically activated and allows remote monitoring.
In order to keep the density in the cleaned ceramic glaze under control, the filter is dried in each new cycle and the system is made ready for the next separation cycle.
Electromagnetic filters can be preferred for raw materials of feldspar and quartz producers working for the same operation as they are used for industrial raw materials.
