In this paper the dewatering and screening process of vibrating dewatering screen is studied by the combination of simulation test and physical experiment
Parameter optimization and mechanism research of double layer variable screen surface vibrating screen In this paper a double deck variable screen surface screening method is proposed to optimize the design of the double deck screen surface
The structure of a real vibrating screen is particularly complicated and mainly comprises a screen box screen mesh and vibration exciters A simplified three dimensional model of the vibrating screen shown in Fig 1 is established to reduce the complexity but realize the actual screening the sieving process in the simulation experiment is
5 Industrial vibratory screeners are generally made of a single deck containing a mesh which is used for screening out oversize agglomerates and foreign bodies from liquids and powder The motor attached to the screen uses an out of balance force to create vibration which sends the materials through the mesh
Overall there is a horizontal trend in the passing percentage In screen 1 the passing percentage of strip particles in the Bin1 Bin4 region was % % % and % respectively In screen 2 the passing percentage of long stripe particles in Bin1 Bin4 region were % % % and % respectively
Working principle of linear vibrating screen The linear vibrating screen is driven by a double vibrating screen exciter When the two vibrating exciters are synchronously and counter rotated the excitation force generated by the eccentric mass cancels each other in the direction parallel to the motor axis and is perpendicular to the motor axis

Gyratory screen is then shaken vigorously in oscillatory manner which is achieved by eccentrics or counterweights Additional auxiliary vibration is caused by balls bouncing colliding against the lower surface of screen Feed rolls over the screen and falls under the influence of gravity and directional shifts The circular or near circular
Vibration mechanisms There are three main types of vibrating mechanisms in screens Long shaft mechanism The long shaft mechanism has masses that rotate at the ends of the shafts and a heavy piece along the shaft that connects the two sides of the screen The shafts are supported by large bearings covered by a flange
The discrete element method DEM is able to simulate the particle particle and particle screen surface collisions It is easier to realize the regulation of the motion form of the screen machine which is now widely used in the optimization study of vibrating screening process Elskamp & Kruggel Emden 2015; Elskamp Kruggel Emden Hennig & Teipel 2015
The displacement and velocity of the material over the screen involves a complex mechanism a function of the mechanical action and particle bed characteristics Harzanagh et al 2018 King 2001 In solid liquid separation using the vibrating screen operation the flow behavior of retained damp particulate matter is related to the cohesive
According to Iizuka [13] vibrating screens are equipment composed of a robust structure called screen box or vibrating part which is supported on springs or rubber cushions equipped with a drive mechanism and deck s surface single or multiple sieving In general there are many vibrating screen models that have been improved over the years as shown by
The SL screen series is designed for classification screening as well as for scalping ore ahead of a cone crusher SL screen SL screens have linear slightly elliptical screening motion and can be installed on horizontal level or on small inclination Mechanism separate from material flow avoiding risk of costly damage and downtime; High
