proper belt tensioning - Bestorq

why does belt tension matter? Proper belt tension is a critical step when installing a belt. V-belts operate on friction; the friction is multiplied by the mechanical advantage of the wedging principle. Correct V-Belt tensioning is the single most important factor necessary for long, satisfactory operation. How you tension a belt at ...


Designing a system of belt conveyors of high capacity, speed and therefore large installed power to transport overburden in open pit lignite mines, is a very complex engineering task.

How to Select and Size Gearmotors for Conveyor ...

The calculation is actually quite simple. If the speed reduction of the chain or belt drive is N:1, then the gearmotor output speed should be N times the speed calculated for the conveyor roller and the torque output should be 1/N times the torque calculated for the conveyor roller.


5 CONVEYOR PULLEY SELECTION GUIDE Pulley/Core Diameter – The outside diameter of the cylindrical body of a conveyor pulley, without coating. Finish Diameter – The outside diameter of a coated pulley (core diameter + 2 times the coating/wrap thickness). Face Width – The length of a pulley's cylindrical body.This area is intended to act as the contact surface for the conveyor belt.

Simple Torque Calculation for Belt Conveyor

If I ever need to calculate approximate conveyor power, for example on simple in-plant inclined conveyors, I often do the following simple calculation. Power = t/h x lift x 2.72 x 1.3 kW From this you can easily calculate the torque, if you have the speed and pulley diameter from the following: Torque = 9.55 x power divided by pulley rpm kN-m

Belt Widths 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.
