The solid-solid separation processes employed by modern coal preparation plants require large amounts of process water. After cleaning, the unwanted water must be removed from the surfaces of the particles using mechanical dewatering equipment such as filters or centrifuges. Unfortunately, the existing processes that are used to dewater fine particles are inefficient in terms of moisture reduction and=or solids recovery. In light of these problems, a new ultrafine dewatering process called the Centribaric TM technology has been developed. This novel device combines centrifugation and pressure filtration within one process to substantially reduce moistures over what can be achieved using conventional dewatering systems. This article discusses the evolution of the Centribaric TM technology from This article was presented at the
