Electromagnetic Filters for Ceramics

Electromagnetic Filters for Ceramics

Since the first ceramics were produced, iron and iron-bearing minerals have caused defects.  The problematic minerals occur naturally in the raw materials, with additional fine iron accidentally introduced during transportation, storage or processing. Effective removal often involves several stages of magnetic separation.  However, the introduction of High-Intensity Electromagnetic Filters proved ground-breaking in terms of removing…

Magnetic Properties of Ceramic Minerals

Bunting Magnetics Bauma

Magnetic minerals and fine iron have plagued ceramic producers since the first glazed pot was produced many thousands of years ago.  Early ceramicists adopted elaborate and colourful patterns to cover any imperfections caused by such contamination.  Over time, the demand for white or single coloured ceramic products increased, making disguising any imperfection increasingly difficult. Ceramic…

Keeping Ceramic Tiles Iron Free

Ceramic Tiles

When fine iron and iron-bearing minerals contaminate the raw material used to produce ceramic tiles, the consequences are costly. Such iron contamination causes visual and structural defects as well as affecting the surface finish in terms of brightness and whiteness.  Tiles failing final quality checks are commonly returned for recycling. Those passing the initial quality…

Keeping Ceramic Tableware Iron Blemish Free

Iron-Specked_Ceramic_Tableware-0537

Fine iron and iron-bearing minerals cause visual and structural defects in ceramic tableware.  Such contamination appears as small dark spots on the surface or is hidden within the body and causes premature cracking of the ceramic.  The cup, saucer or plate is then either rejected or reworked. Iron contamination The problem of iron contamination is…

Iron Separation Technology at Ceramics UK Show

Electro magnetic filter

Successfully removing fine iron from ceramic slips and glazes is vitally important in any ceramics plant.  Such iron contamination is removed using high intensity magnetic separators like those on display on the Bunting and Master Magnets stand 1517 at the Ceramics UK show (10-11 July 2019, Telford, United Kingdom). Iron contamination causes surface defects (black…
