## Vertical Screw Conveyors | Vertical Screw Pump | Vertical Screw Conveyor Design

Vertical screw conveyors: A vertical screw conveyor conveys material upward in a vertical path. It requires less space than some other types of elevating conveyors. Vertical screw conveyor can handle most of the bulk materials provided there is no large lump. The maximum height is usually limited to 30m. A vertical screw conveyor consists of a screw rotating in a

## Screw Conveyor Power Calculation | Screw Conveyor Capacity Calculation | Screw Conveyor Formulae

Power requirement of Screw Conveyors: The driving power of the loaded screw conveyor is given by: P = PH + PN + Pst Where, PH = Power necessary for the progress of the material PN = Driving power of the screw conveyor at no load Pst = Power requirement for the inclination of the conveyor Power necessary for the progress

## Design of Screw Conveyor | Size of Screw Conveyor | Screw Conveyor Capacity Calculation | Screw Conveyor Design Calculation

Design of Screw Conveyor: The size of screw conveyor depends on two factors 1. The capacity of the conveyor 2. The lump size of the material to be conveyed (Maximum dimensions of the particle) Usually there are three ranges of lump sizes which are considered for selection of screw size. These are: ยท A mixture of lumps and fines in

## Screw Conveyor Types | Helicoid Screw Flight | Ribbon Flight Conveyor Screws

Types of screw flight: The screw of the conveyor may be right hand or left hand, the right hand type being the usual design. The threads of the screw may be single, double or triple. The flight of the screws may be made in either of the two ways: 1. As Helicoids 2. As Sectional flight Helicoids Flight: They are
