Calculating Screen Efficiency Example. 3/2/2016 8 Particle Size The closer the particle size to the aperture, the harder to pass it. “Half Size” and smaller go fairly easily. −¼” particle, ½” aperture, e.g. “Near Size” takes a lot more time. 3/8” Particle 3/8” / 1/2” = 0.75 7/16” / 1/2” = 0.875 7/16” Particle

MoreDouble Deck Vibrating Screen is mainly used in desulphurization system of power plant, in flux screening system of steel plant, in the gravel aggregate system of construction industry, etc.. The Double Deck Vibrating Screen research and developed is basing on our high frequency screen, and it is with the character of a low-amplitude but a high-frequency.

More11/09/2012· Screen efficiency is obtained using different equations, depending on whether your product is the oversize or undersize fraction from the screen. The following information is required to calculate the two screen efficiencies;- Qms (f) = Mass flow rate of solid feed. Qms (o) = Mass flow rate of solid in the screen overflow.

MoreWhat is Screen Efficiency? Efficiency = TPH of undersize in feed which actually passes TPH of undersize in feed (should pass) How many TPH should go through? 93.8% passes 1”, so: TPH (-1”) = 0.938 x 500 TPH TPH (-1”) = 469 TPH How many TPH didn’tgo through? 41.1% of the deck overs passes 1”, so: TPH (-1”) Overs = 0.411 x 53 TPH

More01/01/2016· For screening conditions where both crowded and separated screening occur, the overall oversize efficiency is given by (12.56) E iOL = E iO L (C) E iO (L − L (C)) where E iOL, E iOL(C), E iO(L − L(C)) = oversize efficiency for screen lengths L, L C and L − L C,

MoreScreening Theory and Practice 1 Part 1. Theory of Screening The purpose of screening is to separate from a granular substance particles that are smaller than the screen opening from those that are larger. This is not as simple as it sounds, and the difficulties compound as the opening becomes smaller. For example, if a sample of a crushed

More11/10/2019· In other words, the vibration of the screen deck agitates the material causing it to stratify, allowing the larger particles to remain on the top deck and the smaller particles to fall through the openings of the screening surface. Screening efficiency is calculated as the percentage of the undersize materials passing through the openings divided by the percentage of undersize in the feed.

MoreMechanical screening, often just called screening, is the practice of taking granulated ore material and separating it into multiple grades by particle size.. This practice occurs in a variety of industries such as mining and mineral processing, agriculture, pharmaceutical, food, plastics, and recycling.. A method of separating solid particles according to size alone is called screening.
