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 effect.Additionally, the sieving process in the simulation experiment is shown in Fig. 2.

How to determine required screening area. A separate calculation is required for each deck of a multiple deck screen, although the same formula is utilized for each calculation. Screening Area = U = Square Feet: A x B x C x D x E x ... Factor "A" - Basic Capacity :

11-04-2016· Or the screen may consist of concentric drums of increasing diameter to give various separations with one rotating screen unit. The effective area used to find the capacity of a revolving screen is usually taken to be one-third of the diameter of the drum times the length. The quantity of material that can be handled by a screen during a given time depends on the inclination of the axis and the speed of rotation. Frequently, the flat, vibratory screens …

Feeders are positioned after a hopper to control the discharge, dose the solid if necessary, or reach another unit operation while reducing the height of the installation (case of screw and vibrating feeders). 4 feeders are considered here and cover most of the cases in the industry : simple butterfly valves, pneumatic rotary valves or Airlock rotary Valves, screw feeders and vibrating tubes.
