Dewatering (Too Slow, Too Fast) ... One can envision an initial layer of fibers forming adjacent to the forming screen and the rest of the dilute furnish being filtered by this initial layer, which then becomes thicker. Any fines in the furnish will tend to be trapped at "choke points" in the structure of the fiber mat.

mechanical behavior of the screen but include material properties and overall process conditions. 2 Background Dewatering is the process to separate a mixture of solids and liquids. During this process none of the components will be altered. If the target of the process is the solids we speak about dewatering.
In addition, the water content of concentrate and the utilization ratio of tailings recycling water will directly influence the transportation cost and investment cost. That means dewatering machine is an essential link in ore dressing process.
Dewatering / d iː ˈ w ɔː t ər ɪ ŋ / is the removal of water from solid material or soil by wet classification, centrifugation, filtration, or similar solid-liquid separation processes, such as removal of residual liquid from a filter cake by a filter press as part of various industrial processes.
