This means that the benefits of both vibration types are combined in a horizontal screen. Horizontal screens have a stroke range of 14–20 mm and typically run at a stroke of 16–18 mm and a spinning speed of 750 rpm. Between 0.2 and 0.25 meters per second, materials move through the screening medium.Web

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.Web
