Conveyor belts on installations, where the belt width is equal or larger than the conveying length, are increasingly difficult to guide. namely thin belts with little lateral stiffness, particularly at high speed, haveendency to buckle and potentially fold over when fitted on short conveying distances with cylindricalconical pulleys.
The standard speed for most unit handling conveyors is 65 fpm feet per minute which works out to the average speederson walks when carrying0pound box. this pace is ideal for manybut not allorder picking and assembly operations. there are always situations where transport through an area, intorocess, or towardacking operation can be accelerated.

Calculating conveyor speed the conveyor belt speed is calculated as the circumference of the drive roller times the rotations per minute rpm of the motor. if there is any gear reduction, dont forget to apply the ratio to the rpm before multiplying the circumference. conveyor belt speed drive roller circumference motor rpm.
5 conveyor speed for specialised situation, like space constraint in mines or boom conveyor of stackerreclaimer machines, etc. if you are not expert on belt conveyor design, then it is better to restrict your choice to conventionally used speeds which also havepeed range uptops for certain materials.
In the case ofonveyor going downhill where the load is overhauling and the job of the drive is to holdback, it is better to arrange the drive at the tail pulley. in general the speedtorque characteristics of a.c. motors up to 200 hp are defined in standards published by the national electrical manufacturers association n.e.m.a..
Conveyor belt system speedrated speed. belt conveyors are typically rated in terms of belt speed in ftmin. while powered roller conveyors described the linear velocity in similar units toackage, carton, etc. moving over the powered rollers. rated speed applies to apronslat conveyors and dragchaintow conveyors as well. throughput.
The model bsd israction action motion control that indicates whenonveyor belt has slowed or quit moving altogether. the unit can be adjusted as an overspeed, underspeed, or zero speed control. the output of the model bsd can be wired intolc or dcs, or to the optional rms controller or msd controller which haspdt relay to.
