Vibratory Screens come in a variety of sizes. They can range from 4' to 12' wide and 6' to 32' long. The width of the screen determines the carrying capacity of the screen deck, while the length of the screen determines the overall efficiency of the screen. Typically, the length of the screen is 2.5 to 3 times the size of the width.

What are vibrating screens and which are its main applications for use. 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.
For the traditional large vibrating screen, the method to reduce the blinding is to improve the vibration intensity of screen body. The vibration intensity (k = Aω 2 /cosα/9.8) depends on the vibration direction angle (α), amplitude (A) and frequency (ω) of the screen body [24]. During the whole screening process, a large amplitude at the ...
