Multiply the "Bed Depth" factor times the calculated tons per hour the deck is capable of screening and comparing it to the desired production will tell if the deck is sized correctly. and width of the screen the thoeretical depth of material can be calculated.
The superior performance of vibratory processing with GK's unique FINGER-SCREEN™ deck delivers highly efficient separation and classification. The vibratory action spreads material across the deck thereby lowering the bed depth for maximum utilization of the screen area.

VIBRATING SCREEN – CAPACITY CALCULATIONS Throughput per square foot of screen area is the name of the screen game, and no design engineer wants to be considered short in the area of capacity and efficiency. It behooves the buyer/operator to examine and evaluate the data available before committing to any screen type or system.
Screening of Materials and Types of Screens. ... These are (i) gyratory screen, (ii) shaking screen, (iii) inclined vibrating screen and (iv) horizontal vibrating screen. ... there is an optimum retention time beyond which capacity at constant efficiency is governed only by bed depth.
ELRUS inclined vibrating screens maximize flow and coverage for increased production with minimal maintenance and downtime. By focusing on the three essential factors of shaft design – speed, throw and location – ELRUS has developed a screen system that provides efficiency, capacity and gradation control while minimizing vibration transfer to surrounding structures.
Optimization of vacuum vs. vibrating screen for SRT separation. The vacuum and vibrating screen studied in this experiment applied different forces onto the granules. The vacuum screen focused on the application of normal forces.
If the grainbed gets too shallow, i.e., from lautering too little grain in too large a tun, then an adequate filter bed won't form, the wort will not clear, and you will probably get hazy beer. A minimum useful depth is probably about 4 inches but a depth of between 8-18 inches is preferable.

width of screen or 2-3 m3/tonne for coal. Multistage washing is also recommended for a higher efficiency. Bed depth The allowable load C in t/h per m-screen width for the drain and rinse screen is: C = 8 √d2 a x ɣ 2 pr t/h/m (2)
A higher bed of material will reduce the screening efficiency. Feeding capacity for each mesh size depends on the width of the screen. To get efficient screening results the depth of material bed must be at least 2 times the mesh hole diameter on the end side of the surface. Then volume of oversize will determine the width of the screen.
capacity of the vibrating screen. • The vibrating screen capacity is determined: • Using a standard sizing formula (9 variables). • Basic capacity of each deck opening. • Unique factors of that application. • Maximum bed depth allowed for the openings and particle size.
the test sieve1, which determines the depth of the static material bed before the shaking starts. The most commonly used measure of screen efficiency is the cumulative weight of material that has passed the screen in any time interval, compared to the total weight of …
The depth of the bed at the discharge end of the screen indicated the effectiveness of the bed stratification and the ability of particles to have an opportunity to pass through the screen. The bed depth, D, in inches at the discharge end should be limited to limit to 4 times the screening opening for solid density > 100lbs/ft 3 or 3 times for ...
Horizontal screens provide high g-forces to vibrate and move the material down the length of the screen. Horizontal screens typically offer better efficiency (accurate particle sizing) than inclined screens because the material is retained on the screen longer, with a slower travel rate to the end of the screen.
The curves suggest that this depth effect may disappear at depths of about 1.0 to 1.5 ft. The flume width influenced the bed-form characteristics in various ways. Bed forms in wide channels can have heights and travel rates quite different from those observed in narrow chan nels. Except for runs at the 0.1-ft depth, bed forms did not be
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.
Modular Welded-Wire Screen Panels Boost Open Area and Wear Life. By Carol Wasson. Screening efficiency is measured by the percentage of material that passes through the screen deck when compared to the total amount of the same-size material in the product stream.
The aspect ratio of the screen (length/width ratio) must be determined by considering the depth of the bed of particles on the screen. An approximate guide is the restriction of the bed depth at the discharge end to no more than 4 times the mesh size.
