The Crusher’s Arch Enemy – Tramp Metal

Tramp Metal Villain

Crushing quarried aggregate is a key process stage of most quarries and when recycling demolition waste.  Effectively protecting the crusher from rogue tramp metal damage prevents production losses and repair costs. The wide range of available crushing technology enables the production of optimally sized aggregate.  Whereas Jaw and Gyratory designs commonly feature as primary crushers,…

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…

Wet High Intensity Magnetic Separation Testing

Wet High Intensity Magnetic Separation Testing

The electromagnetic laboratory-scale Wet High Intensity Magnetic Separator (WHIMS) removes fine magnetics and para-magnetics from mineral slurries.  Handling minerals in a slurry or suspension is preferable for many processors, especially when beneficiation involves wet processing.  Additionally, a wet process often produces a better separation for very fine materials. In this educational video, Professor Neil Rowson…

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…

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…
