Electromagnetic filters for European ceramics producer
A leading European manufacturer of luxury ceramic sanitaryware has placed an order for nine high-intensity Electromagnetic Wet Filters from Bunting Magnetics. The units will be deployed across production sites in Poland, Portugal, and Ukraine to enhance the purity of ceramic slips, glazes, and bodies.
Bunting’s Electromagnetic Wet Filters utilize powerful magnetic fields – up to 10,000 Gauss – to remove fine iron and paramagnetic minerals that cause defects such as spotting, discoloration, or cracking. These issues are especially problematic in high-end white and pale ceramics, where quality consistency is critical.
Each filter features a computer-designed electromagnetic coil surrounding a stainless-steel matrix. During operation, ceramic material is pumped through the filter, where magnetic particles are captured by the matrix. The system automatically cleans itself by shutting down the magnetic field and flushing out collected contaminants.
Seven of the filters ordered for this project operate at 2,500 Gauss and will be used for processing ceramic slip. The remaining two, rated at 5,000 Gauss, are designed for glaze treatment. The combination of oil-cooled coils and energy-efficient design ensures consistent thermal performance and low operating temperatures.
“By adopting this advanced magnetic separation technology, our client expects to significantly reduce product rejects and material waste,” said Bradley Greenwood, Head of International and European Sales at Bunting Magnetics.
The investment underscores the growing importance of precision filtration technologies in ceramic manufacturing, where maintaining product quality while minimizing rework and recycling costs is a key driver of operational efficiency.
