A factorial experimental design using the response surface methodology was conducted to optimize the dewatering performance of the SBF prototype unit. The clean coal slurry sample used as the dewatering feed was a combined spiral and flotation product with a mean particle size of 400 micron and an ash content of 19.2%.

Dewatering Performance of Vibrating Screen

Dewatering rate optimization Fig. 5 is a schematic diagram to show the relationship between dewatering rate and pressure propagation. It is seen that low dewatering rate will cause gentle pressure funnel and long investigation distance, while high dewatering rate is companied with sharp pressure funnel and short investigation distance.
