AGGREGATE SCREENING OPERATIONS

Particulate emissions occur whenever sand, soil, and/or aggregate is mechanically separated by single or multiple deck screens. The following calculation procedure to estimate screening operation particulate emissions is based on Section 11.19.2 of AP-42 (1/95). Ea = Ua x EF x Ci x (1 e) Eh = Uh x EF x Ci x (1

Modeling screening efficiency with vibrational parameters

Jul 01, 2010 The efficiency of particle screening was studied over a range of vibrational parameters including amplitude, frequency and vibrational direction. The Discrete Element Method (DEM) was used to simulate the screening process. A functional relationship between efficiency and the parameters, both singly and combined, is established.
