Thread: Instrumentation for Pipe Conveyors

  1. Instrumentation for Pipe Conveyors

    What are the correct instruments to consider for a pipe conveyors:

    Zero Speed Detector
    Pullcord
    Plugged chute detector
    Beacon
    Horn
    Belt Rip Detector??
    Monitoring System?(embedded sensors?)
    Others?

    Regards,

    In Addition, You Need:

    Plugged Pipe @ Load Station - Shutdown
    Seam Rotation - Warning & Shutdown - big problem if moving material in two directions on top & bottom strands - no spillage allowed
    Side Travel Monitor@ Head Discharge - Warning & Shutdown
    Take-up Overtravel - Warning & Shutdown - Too Long & Too Short

    All the standards:

    Motor Current Overload, Bearing Heating & Vibration
    Motor Load Sharing Imbalance - Warning - pulley material buildup or pulley lagging failure
    Reducer Oil Flow, Heating, Vibration
    Pulley Pillowblock Bearing Heating & Vibration

    Specials:

    Return Strand Spillage Control at Head Discharge - transitiioning back to pipe
    Pulley Cover Wear - outer belt cover wear due to mal-adjusted pulley alignment, mal-adjusted idler alignment

    Others can do more:

  4. Hi,
    You are right Mr. Lawrence. Here you can use plugged pipe, seam rotation, side travel monitor and some more important products. Expect of this there are no more instruments for pipe conveyors. As we all know Pipe conveyors are an environmental friendly solution for conveying bulk material with zero spillage and ability to cover terrain difficult to negotiate by conventional conveyors. So it’s necessary to use right instruments for this.

    Pipe conveyor problems

    Common problems in pipe conveyors are
    1.0 Not selecting proper belt and belt manufacturer.
    2.0 Motor is short of power
    3.0 Pipe conveyor pulley failure
    4.0 Pipe conveyor belt skewing
    5.0 Pipe not opening at head pulley
    Following precautions are to be considered while installing a New pipe conveyor
    1.0 Pipe conveyor expert should be involved in design of pipe conveyor
    2.0 Only experienced belt manufacturer to be selected for pipe conveyor belt
    3.0 Belt Selection is very very important. Most important is belt rigidity / Belt troughablity . If belt is not selected properly pipe formation will not be proper and conveyor may require abnormal power
    4.0 Motor shall have sufficient margin to cater for new Belt rigidity
    5.0 Belt profile should be very carefully selected considering proper horizontal and vertical curves considering pipe diameter, belt tension and belt rigidity
    6.0 Transition distances for pipe formation should be properly designed based on type of belt , tension rating and pipe diameter
    7.0 Idler diameter and spacing should be properly selected
    8.0 While selecting pulley shaft diameter higher shaft sizes to be selected to cater for higher tension rating due to stiff belts and higher motor ratings
    9.0 Fabrication and erection of conveyor Galleries and idler supporting structure should be very accurate particularly at curve portions.
    10.0 During commissioning alignment of idlers and pulleys is very important

    Instrumentation for Pipe Conveyors

    Most important sensor in pipe conveyor is providing a sensor before pipe formation which can detect overloading of material / bigger lumps and stop the conveyor before reaching the overloaded material to pipe formation zone .
    In pipe conveyor we cannot overload the conveyor as well as lumps bigger than recommended size can not be transported .
