Ultrafine coal dewatering: Relationship between

2014-12-10  Dewatering process was done by means of a Buchner Vacuum process with a maximum vacuum pressure of 0.8 bar (80 kPa). Coal suspension was poured into a funnel of 110 mm in diameter which was attached to the filtrate flask. Another flask was also put in between the pump and filtrate tank in order to reduce the pump's oscillation effect on the process.

An investigation on dewatering kinetics of ultrafine coal

2003-6-1  Ultrafine coal dewatering is of great importance to the coal industry due to its impacts on the handling and utilization characteristics of coal products.
