Electro Magnetic Filter
High Intensity Magnetic Separation at XVIII ECerS
The XVIIIth Conference of the European Ceramic Society takes place in Lyon, on 2-6 July 2023. On stand 19, Bunting is highlighting the necessity of using high-intensity magnetic separators to remove iron, iron-bearing and paramagnetic minerals to reduce defect rates and improve surface brightness. Paramagnetic Minerals and Fine Iron Contamination Materials used in the manufacture…
Read MoreBunting-Redditch 2022 Review
After a very optimistic start to 2022, the year presented the world with new challenges to overcome. Two years of negotiating the choppy waters of a pandemic was replaced by rising energy prices, material shortages and price rises, and increased interest rates; all sparked by the globally-condemned invasion of the Ukraine by Russia. Despite the…
Read MoreElectro Magnetic Filter for European Ceramics Producer
A leading German ceramic manufacturer is cleaning ceramic glaze with a high-intensity Electro Magnetic Filter designed and manufactured by Bunting. The successful removal of fine magnetics reduces finished product rejects and increases surface brightness. High-Intensity Electro Magnetic Filters The Electro Magnetic Filter provides one of the most effective methods of removing problematic fine iron and…
Read MoreHigh-Intensity Magnetic Separators at Ceramitec
High-intensity magnetic separators play a key role in the manufacture of ceramics and the processing of ceramic raw materials, as highlighted at Ceramitec 2022 on Bunting’s stand (on stand C1:511). Keeping Ceramics Iron-Free Fine iron and magnetic minerals cause defects in any ceramic product, whether that is tableware, sanitaryware, tiles or technical ceramics. The iron…
Read MoreElectromagnetic 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…
Read MoreMagnetic Properties of Ceramic Minerals
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…
Read MoreKeeping Ceramic Tiles Iron Free
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…
Read MoreKeeping Ceramic Tableware Iron Blemish Free
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…
Read MoreKeeping Ceramic Sanitaryware Iron Free
Sanitaryware is a commonly used term in the ceramics industry referring to sanitary appliances found in toilets and bathrooms. Traditionally, bathroom bowls, cisterns, bidets, urinals and washbasins are made from porcelain (a ceramic material made from clay that might be described as ‘vitreous china’ when coated with enamel). This might be referred to as ceramic,…
Read MoreIron Separation Technology at Ceramics UK Show
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…
