This type of feeders are generally located under the open stock-piles or under the bunkers to feed the primarily crushed and stocked material to the belt conveyors or crushers (tertiary or secondary). They are hung underneath of the bunkers with helicoid springs or stand on a steel construction frame.
Drive system consists of two vibromotors rotating conversely. By means of this system they have linear motion.
For abrasive material feeding trough is covered with abrasion – resistant steel plates.
