Oct 17, 2010 Counterweight calculation. Hi There, I am trying to calculate the take up weight for one conveyor. As I understand, I should check two criterias against sizing the take up. 1- Minimum tension in order to build the determined sag in belt conveyor between idlers. 2- Minimum tension required in slack side T2 of the drive in order to prevent the ...
Selection and Calculation of Apron Feeder. Apron feeder can be divided into heavy, medium and light apron feeder, which featuring in large granularity bulk density and delivery capacity of conveying material, generally above 600U h. This also determines the sufficient strength of the heavy plate feeder itself including rack, chain plate ...
The gravimetric feeder compensates for the variation in bulk density and feeds a fixed weight of coal in response to a boiler fuel demand. This ability to accurately weigh the coal provides significant improvement over volumetric types in terms of matching the fuel delivered by the feeder to the actual process energy required on coal fired units.
