The deck position factor K5 Screens that are lower down in the deck receive undersize from the screen above and can handle less material than a screen that takes fresh feed. The capacity decreases with position according to capacity factor K5 K 5 1.1 0.1S (4-10) where S represents the deck position; 1 for top deck, 2 for 2nd deck and so on.
Oct 21, 2004 Dear all, How do we calculate the efficiency of screening? For a PU deck Vibro screen for 30 mm separation ( cap 62.5 TPH, Bulk Density 0.55 T/m3), if undersize fraction contains 8 %,+30 mm fraction and Oversize contains 5%,30 mm fraction, what shall be screening efficiency? What is the industry standard for screen efficiency?
The high frequency vibrating screens achieves a high efficiency of separation and differs from its counterparts since it breaks down the surface tension between particles. Also the high level of RPMs contributes to increasing the stratification of material so they separate at a much higher rate.
Vibratory Screens. Screening is an important part of processing and is used to separate material according to its size. Material is typically fed to a single-, double- or triple-deck screen
OF THE SAME VIBRATING SCREEN BODY. Efficiency gets less as the transfer to decks below has the material passing landing further down each LOWER DECK POSITION. Efficiency of Vibrating Screens mining application. High Efficiency Vibrating Screen for Sale Dear all, How do we calculate the efficiency of screening?

A circle-throw vibrating machine is a screening machine employed in processes involving particle separation. In particle processes screening refers to separation of larger from smaller particles in a given feed, using only the materials' physical properties. Circle throw machines have simple structure with high screening efficiency and volume.
Jun 30, 2018 Vibrating screen calculation part-4 Actual capacity of the screen F = Fa x R x W Where R = Efficiency factor W = screen width (m) Fa = Basic feed rate (ton/m/hour) The basic feed rate to a screen is calculated by the formula Fa = (73.14 x La x pb) /C Where Fa = 
How to determine required screening area. A separate calculation is required for each deck of a multiple deck screen, although the same formula is utilized for each calculation. Screening Area = U = Square Feet: A x B x C x D x E x F x G x H x J Applies for multiple deck screens. Total screening area is available for top deck separation.
