ABSTRACT

ABSTRACT: Any wet applications in bulk material processes ultimately raise the question of dewatering. Usually the purpose of dewatering is to put the solid material into an either sellable or at least transport-ready state. A variety of machinery options exist for that purpose. Each of these come with there very own range of usage and there pros and cons. This paper will evaluate a range of processing equipment for its dewatering capabilities and operating parameters. Special focus will be set on environmental aspects as energy and water consumption and the effects the performance of dewatering equipment has on the entire process. Vibrating screens have been proven to be an economical means for a multitude of dewatering applications ranging from aggregates over coal to food. Operating conditions that affect the dewatering performance will be discussed. These parameters are not limited to the mechanical behavior of the screen but include material properties and overall process conditions. In detail the effect of the following parameters will be discussed:

• Feed material properties • Layer of material • Screen media, openings, arrangement • Overall screen dimensions and inclination • Operating parameters like speed and stroke.
