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 …

Also called simply screens, a vibrating screen is formed by a vibrant chassis that supports in its interior one or several surfaces or elements of screening. The screens serve to classify the different particles by size, starting from a bulk product in a continuous process. The inlet material (the raw product) advances from the part where the ...
