Selection of vibratory conveyor: The oscillating motion of the trough is achieved via specially designed inclined arms and an eccentric shaft driven by a motor through V-belts. The eccentric shaft is mounted on anti friction bearings and has V-pulleys at both ends with weights on them to counteract the unbalancing force. The rotation of the eccentric shaft provides a forward
Vibratory conveyor / Oscillating Conveyor A vibratory conveyor essentially consists of an open or closed trough or pipe, generally horizontal but not always so, and which is elastically supported on a base structure or suspended from an overhead structure by springs. The trough or pipe is caused to oscillate at high frequency and small amplitude by an appropriate drive mechanism.
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
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: 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: · A mixture of lumps and fines in
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
