A screw feeder is primarily designed for handling very low-tonnage outputs, with a critical requirement for positive and controlled material discharge. This type of feeder offers the advantage of easy enclosure, making it effective at preventing the release of dust. Consequently, it allows for a sealed hopper and chute arrangement from the hopper to the delivery point. The basic structure of a screw feeder includes a helical screw that rotates below the hopper outlet and is driven by an external power source. The screw can have a fixed pitch or a variable pitch with smaller spacings in the rear and gradual increases in pitch towards the discharge end. This design ensures that the material moves efficiently within the rear portion of the hopper. Novelty Structures supplies various type of Feeders for Mineral Processing Plants. * Belt Feeders * Screw Feeders * Apron Feeders * Rotary Table Feeders
