ACARP Abstract

In some plants water carry over on the drain and rinse screens can cause detrimental effects to the medium as the non-mags within the medium are diluted which can lead to an unstable medium. The presence of slimes in the medium will increase its stability by virtue of the particle size and low mineral density, and on operating plants the level of build up of these slimes is

Selection Tips for Vibrating Screens Coal Age

In coal preparation, screening machines serve two purposes: sizing and media recovery. Oftentimes, the initial screening is performed by a scalping screen located outside the plant. This prevents the screens inside the plant from becoming overloaded. The deslime screens make the next cut and most prep plants size to minus 1 mm. The media, or magnetite, is recovered by drain-and-rinse
