Current screen capacity calculations do not take into consideration enough of the factors affecting screen efficiency The old formulas were designed to keep calculations short and manageable for manual calculation The common use of computers in today s world makes it possible to do more complex screen capacity calculations in much shorter time
Water moves through a watershed as sheet flow shallow concentrated flow open channel flow or some combination of these The type that occurs is a function of the conveyance system and is best deter mined by field inspection Travel time T t is the ratio of flow length to flow velocity T L t V = 3600 [eq 3 1]
Figure 1 Double roll crusher geometry Thickness of the RollFigure 1 is the geometry of a double roll crusher with a spherical particle about to enter the crushing zone of a roll crusher and is about to be nipped [4] [5] For rolls that have equal radii and length tangents drawn at the point of contact of the particle
