A vibrating screen machine is a screening technology that allows for the classification of solid materials based on their size and shape. As the name suggests, this machine operates by applying vibrations to the screen to loosen and fractionate the material. A typical vibrating screen machine consists of a frame that holds the screen, a ...

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.

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 ...
