  Screw Conveyor Bulk Material Characteristics

  Recommended trough loadings of 15 30 and 45 percent were developed based on the characteristics of bulk materials. The recommended trough loading for a screw conveyor is a function of the density abrasiveness and flowability of a bulk material. For a given capacity screw conveyor size and speed is determined by trough loading percentage.
