For example if a 10 foot long conveyor moves five 50 pound boxes simultaneously at a belt speed of 50 feet per minute on a conveyor belt with a weight of 3 lbsft on a slider bed with a frictional coefficient of 05 then the belt pull is calculated as follows first calculate total weight
Coal conveyor drive unit calculation screw conveyor speed calculation for horizontal conveyors coal conveyor drive unit calculation some people use one 20 degree idler at each end of a 35 degree conveyor and 20 degree and 35 degree idlers on each end of a 45 degree conveyor the object of this approach is to have the rolls sloped to suit the belt contour between the last regular or impact
The wrap factor can be as small as 008 for dual drive systems with rubberlagged drive pulleys an automatic takeup and 420 of wrap angle or as large as 12 for a single drive system an unlagged pulley manual takeup and 180 of belt wrap next it is important to calculate t2 sag slack side tension required to prevent belt sag sag
Belt speed expressed in feet per minute fpm sd x rpm x 2618 x 1021 belt load at one time when the load is known per square foot p g 1 x cin feetx w in feet at one time when load is known by pounds per hour pg 2 s x 60 x cin feet horsepower level conveyors hpf x s x pm33000 inclined conveyors hpp x bpmx f
The calculated speed is too high the calculation must be done by changing a parameter we can select a diameter larger d015 m the calculation is run again and this time a speed of 62 rpm is calculated it is less than the max recommended speed the screw design can be selected
Conveyors maximum inclination maximum conveyor slopes for various materials efficiency of small machine elements friction and efficiency in bearings and roller chains fan affinity laws affinity laws can be used to calculate volume capacity head or power consumption when speed and wheel diameters are changed
Apr 10 2009 we need most of the information i mentioned in my earlier post ie gearbox conveyor roller and coupling inertia gearbox ratio and output speed and power conveyor roller diameter etc basically whatever you have given to the conveyor manufacturer in order for him to tell you a 400kw motor is required
Mar 22 2017 i have to drive a conveyor at a speed of 760mmmin to drive this i am using a drive system which consists of a small sprocket mounted on the output shaft of the gearbox this sprocket is connected to a larger sprocket by means of a chain a shaft from the larger driven sprocket is connected to the main conveyor sprocket on which the conveyor
Calculating chain speed higher chain speeds with attendant power usually create faster cutting speeds at the same time there is an inverse relationship between faster cutting speed and the service life of saw chain guide bars and drive sprockets formula for chain speed calculation take chain pitch and multiply x two
Apr 09 2015 the drive does not know what the linear speed of the conveyor is ut only knows what frequency it is sending to the motor you will need to correlate the motor rpm at 60 hz presumably it is a 60 hz motor with the gear ratio of the conveyor system to figure out what the linear speed is
This article will discuss the methodology for the calculations of belt conveyor design parameters with one practical example of the calculations and selection criteria for a belt conveyor system calculations include conveyor capacity belt speed conveyor height and length mass of idlers and idler spacing belt tension load due to belt inclination angle of the conveyor coefficient of
With that input the controller can monitor any speed differential between the primary conveyor belt and the secondary conveyor belt any time that difference exceeds tolerance the controller can command the drive to speed up the motor until the speed of the primary belt
How to calculate conveyor drive speed categoryhobbies release time20141225 views130 with a little ingenuity you can perform a short experiment to determine the linear speed in feet per second of the motor that drives a conveyor belt the trick is in the fact that the linear speed on the edge of a bicycle tire or motor wheel touching
Enter any 3 known values to calculate the 4th if you know any 3 values pulley sizes or rpm and need to calculate the 4th enter the 3 known values and hit calculate to find the missing value for example if your small pulley is 80mm diameter and spins at 1000 rpm and you need to find the second pulley size to spin it at 400 rpm enter pulley1 80 pulley 1 rpm 1000 pulley 2 rpm 400 and
Conveyor application formulas today many of these formulas are incorporated in available software that allows for the immediate analysis and generates a complete list of components either for a new conveyor or for problem resolution on existing conveyor systems the following formulas may be helpful for quick analysis of limited applications

Note the actual motor horsepower required to drive the loaded conveyor system is dependent on the method used to reduce the speed the motor to the required speed of the conveyor drive losses must be taken into consideration when selecting the motor and drive equipment
How to calculate the speed of the conveyor belts quora aug 02 2018 answer wiki 2 answers hii measure the diameter of the rollers around which the conveyor belt is wrapped multiply the diameter of the roller by pi 314159 this calculation yields the circumference of the rollers every time the roller spins one revolution the conveyor is moved a linear distance equivalent to the circumference
Horsepower ratings are calculated according to the standard speed listed for that conveyor when increasing the speed more horsepower may be needed to drive the load as a rule of thumb it takes twice as much horsepower to move a given package at 130 fpm than at 65 fpm the formula below may help to determine the approximate power

Calculate the speed of each pulley by dividing the drive speed by the pulley ratio for example given a drive speed of 750 rpm the speed of the first pulley 7502 375 rpm and the speed of the second pulley 750127 591 rpm
