01-01-2016· The oversize from a 12.5 mm aperture screen was fed to a crusher. The efficiency of the screen was 80%. The product size from the crusher was 80% minus 12.5 mm at a close set of 12.5 mm and was returned to the screen for sizing. The initial feed to the screen was 120 t/h and the screen undersize was also 120 t/h at steady state.

01-05-2011· Screening efficiency versus screen length: varied amplitude and screen inclination Vibration amplitude mainly influences the kinetic energy of the particles. Large amplitudes contribute to energy transportation and stratification and also make the particles bounce higher and further [13] .

In terms of sieving efficiency fitting, Grozubinsky et al. and Chen and Tong have, respectively, established formulas between the sieving efficiency and sieving parameters such as amplitude, vibration frequency, vibration direction angle, particle size, and screen mesh size based on a probabilistic model and a discrete element model, but these formulas only reflect the relationship between the ...

Chromatography - Chromatography - Efficiency and resolution: There are two features of the concentration profile important in determining the efficiency of a column and its subsequent ability to separate or resolve solute zones. Peak maximum, the first, refers to the location of the maximum concentration of a peak. To achieve satisfactory resolution, the maxima of two adjacent peaks must be ...

This establishes the “safe hanging weight” of the screen. This is accomplished with the formula shown here: Where: Y cs = Yield point of continuous slot screen (lbs) S = Yield strength (mild steel = 35,000 psi) r = Radius of rods or diameter/2 (inches) n = Number of rods. j = Joint efficiency of connection between screen and weld. ring ...
