calibration of Belt weigher system for inclined coal conveyor
We have installed inclined belt weigher in coal handling system. supplier gave us one calibration rod (weight 4.462 kg) for calibration purpose. now when we put this rod on load cell indicator shows 23 kg. ,supplier does not provide any details about how this weight come. based on our knowledge we found following result how 23 kg come.
my question is below formula is right or wrong? in wrong what is correct formula to determine belt weight
is there any significant of inclination angle or troughing angle in weigh measurement?
*technical details
material-coal
design capacity-100 TPH
troughing angle- 35 deg
belt inclination -10.5 deg
belt width-800mm
spedd1 m/s
weighr measuring span- 1.60 mtr
also we have 2 weighing idler & one pre idler & one post idler for one load cell
Formula
Std. weight= Y
=Y * 4(inclined belt weigher designed such a way actual weight transfer is 1/4 of the weight)
=(Y * 4 )/cos 35calibration factor For inclined Belt Weigher
In our case
Std. weight=Y4.642(calibration rod weight)
=Y *418.568
=(Y*4)/cos 35
=23Kg
Flow rate (TPH)=(weight/mtr)*(mtr/sec)
=(kg/mtr)*(mtr/sec)
=kg/sec
=(kg/sec)*3600 (we convert sec into hour)
=kg/hr
=(kg/hr)/1000 (we convert kg into tph)TPH formula for inclined belt weigher
=TPH
in measurement we are used one load cell & 2 idler
=(Kg/mtr)14.375( Distance between 2 measuring idler & half of the pre idler & post idler is 1.60 mtr )
=23/1.6
=(kg/mtr) *3.651.75( We convert kg into tph)
=TPH51.75

I would think the operating manual provided for your conveyor belt scale should tell
you that the rod represents the tare weight of the representative belt length being
belt length corresponding to the rods actual length. ■
