Wet screening is when the feed is fed onto the screen along with water or washed across the screen by jets of water The risk with wet screening is that fine material may be lost as mud/paste on the screen surface or the fines may be suspended in water and carried over to the oversize launder Wet screening is generally preferred because it...
screening media Wirecloth maybe woven wire or other media such as urethane rubber or plating used for particle sizing B the Basic Capacity is the inherent ability of each square foot of wirecloth to sort rock It depends on the wirecloth opening size and design of the screen For example 2 wirecloth has a much higher basic...
