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.
