The belt widths are as follows 18 24 30 36 42 48 54 60 72 84 and 96 inches The width of the narrower belts may be governed by the size of lumps to be handled Belts must be wide enough so that any combination of prevailing lumps and finer material does not load the lumps too close to the edge of the conveyor belt

Conveyor Tension and TakeUp Systems Page 3 1 PREAMBLE A conveyor belt is a very efficient machine for conveying bulk material over any distance Optimizing the design of a conveyor belt for throughput distance speed and reliability versus cost is an ongoing quest Tension in a conveyor belt is

2 heavy duty belt conveyor and chain conveyor can via increasing additional weight and eliminating mechanism jam to solve When adding the configuration of the tensioning device no slipping is ok And remember don’t add too much otherwise the belt conveyors will reduce service life because of bear unnecessary excessive tension

3 Belt conveyor scales provide a means of weighing bulk materials while in motion The obvious advantage over static weight systems is that the flow of material need not be interrupted

BELT CONVEYOR INSTALLATION AND MAINTENANCE Bulletin CAUTION Do not operate the conveyor without safety guards in place and properly adjusted WARNING LOCK OUT EQUIPMENT POWER PRIOR TO ANY MAINTENANCE A STORAGE HANDLING AND INSTALLATION New conveyor belt should be stored upright in the factory package until used

counterweight effect in a belt conveyor Problems Related to Excessive Counterweight on Heavy Duty Belting tension conveyor belt the one that brings the rock out

A belt conveyor scale is a device that measures the rate at which bulk material is being conveyed and delivered on a moving conveyor belt Further it can compute the total mass of material conveyed over a given period of time

FGH is the downhill force FG is the weight force Gravity acts straight down the weight of the conveyor belt and the support force acts away from the conveyor Since the conveyor is sloped there is a net force acting down the slope

Counterweight is a major component of the working tension of a belt In the case of our belt problem the increased weight to 25000 lbs raised the actual working tension for 680 lbs or 85 of the belt’s rated working strength to 907 lbs or 114 Increasing counterweight tension can seriously affect system performance
