Coal screening & preparations

Mechanical screening is the practice of taking granulated ore material and separating it into multiple grades by particle size. A screening machine consist of a drive that induces vibration, a screen media that causes particle separation, and a deck which holds the screen media and the drive and is the mode of transport for the vibration.


There are physical factors that makes screening practical. For example, vibration, g force, bed density, and material shape all facilitate the rate or cut. Electrostatic forces can also hinder screening efficiency in way of water attraction causing sticking or plugging, or very dry material generate a charge that causes it to attract to the screen itself.


As with any industrial process there is a group of terms that identify and define what screening is. Terms like blinding, contamination, frequency, amplitude, and others describe the basic characteristics of screening, and those characteristics in turn shape the overall method of dry or wet screening.


Dewatering is the removal of water from solid material or soil by wet classification, centrifugation, filtration or similar solid-liquid separation process such as removal of residual liquid from a filter cake by a filter press as part of various industrial processes.


Construction dewatering, unwatering or water control are common terms used to describe removal or draining groundwater or surface water from a riverbed, construction site, caisson or mine shaft by pumping or evaporation. On a construction site, this dewatering may be implemented before subsurface excavation for foundations, shoring or cellar space to lower the water table .


This frequently involves the use of submersible "dewatering" pumps, centrifugals (trash) pumps, eductors or application of vacuum to well points.
