Five Magnetic Separator Myths

five Magnetic Separator Myths

Often ascertaining the best Magnetic Separator for any given application is not straightforward.  To complicate the decision-making process further, many companies supplying magnetic separators provide a wealth of information such as Gauss levels and the amount of metal that the Magnetic Separator can actually capture. Such details are often difficult to verify and may even be meaningless. In this…

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

Keeping 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…

Measuring Magnetic Separator Power

Bunting Magnetics Pull Test Kit

A Magnetic Separator attracts, captures and holds magnetic particles.  The magnetic strength needed to successfully separate such problematic ferrous metal contamination is commonly stated in a magnetic separator supplier’s quotation or specified in the tender.  This ‘Magnetic Strength’ is usually referenced in terms of ‘Gauss’, a unit of measurement.  However, as it is difficult to accurately measure…

Keeping Ceramic Tableware Iron Blemish Free

Keeping 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…
