The iScreen is a 1ft x 2ft (30cm x 60cm) mini vibrating screen designed to work with the iCON150. It can also be used for general small volume pilot plants or screening in small-scale mining. On the screen, press the green button on the VFD to start the vibration. Use the arrows to increase the vibration to the maximum. Try a small amount of sand in the sieve. If wet material appears to bounce downhill, change internal motor rotation.
