investigation in stressing of conveyor belt drums

The deflection drum is automatically brought to the perfect position to keep belt tension constant and ensure straight belt tracking In case an incorrect belt tracking line arises the tensioning and tracking system immediately corrects its position ensuring a longer belt lifetime

Jul 01 1970 Experimental investigation of the stress condition in belt conveyor drums Conclusions 1 The tensiometric method of investigation shows that the agreement between theoretical and experimental data is satisfactory

An elastic analysis showed that high cyclic bending stresses were produced at the plateboss welds when the drums were loaded by the tension in the conveyor belt The stress ranges in the failed

mechanical drive for belt conveyor So friction is the driving force In order to raise transportation efficiency of belt conveyor driving force of drum must be increased Energy saving efficiency friction fire safety maintenance and inspection are the other key factors of belt conveyor design

from Newtonian rigid body dynamics which yields the belt stress With this belt stress the maximum extension of the belt can be calculated This way of determining the elastic response of the belt is called the quasistatic design approach For low capacity and small beltconveyor

Dec 05 2016 PurposeLargescale beltconveyor systems are extensively used in open mines to continuously transport bulk material Conveyor pulleys are critical components and failures have significant financial consequences due to extended downtime Aiming at increasing their durability two critical spots are identified the drum and the welds between endplates and drum Alternative

Abstract The shaft of a conveyor belt drive pulley failed in service An investigation was performed in order to determine the failure root cause and contribution factors Investigation methods included visual examination optical and scanning electron microscope analysis chemical analysis of the material and mechanical tests

CONVEYOR PULLEY SELECTION GUIDE STEP 2 Determine the Anticipated Belt Tension of the Conveyor System Belt tension measures the degree to which the conveyor belt is stretched or held taut and is typically measured in pounds per inch width PIW Conveyor pulleys and shafts of a larger diameter are better equipped to handle

Fig 3 Stress distribution in conveyor belt plies along the splice Maximum stress values in the belt occur at step contacts and are 4 where z number of plies in the belt k stress concentration ratio in plies at step contacts dimensionless m Fb stress in the belt outside the splice area in

This paper uses the KelvinVoigt viscoelastic model to establish the continuous dynamic equations for tail hammer tension belt conveyors The viscoelastic continuity equations are solved using the generalized coordinate method We analyze various factors influencing longitudinal vibration of the belt conveyor by simulation and propose a control strategy to limit the vibration

The deflection drum is automatically brought to the perfect position to keep belt tension constant and ensure straight belt tracking In case an incorrect belt tracking line arises the tensioning and tracking system immediately corrects its position ensuring a longer belt lifetime

A more favourable case of conveyor belt operation is in the usual mode of operation which starts approximately 30 s after starting the drive while the bucket wheel excav ator is near the conveyor belt drive position II II Fig 2 In this mode loads are up to 25 times smaller During exploitations in pits the conveyor belt is moved
