Therefore, initially, you will need to estimate a belt tension for your system using Belt Drives in order to find the contact angles (α). From which you must determine the required belt tension, based upon the necessary output torque: t = T.μ.α / π.r and subsequently make a final calculation by applying the corrected belt tension (t).

The conveyor must occasionally be able to accelerate the mass at 0.5m/s^2. The width of the belt conveyor is 457mm. In this case our variables are 20kg for mass, 0.5m/s^2 for acceleration, 10 degrees for angle theta, and 120N for deformation force. These variables lead to a required driving force of 227.8N and 500mm/s.

History. Primitive conveyor belts were used since the 19th century. In 1892, Thomas Robins began a series of inventions which led to the development of a conveyor belt used for carrying coal, ores and other products. In 1901, invented and started the production of steel conveyor belts. In 1905 Richard Sutcliffe invented the first conveyor belts for use in coal mines which ...

Shifting idlers in this way should be spread over some length of the conveyor, or radial stacker, preceding the region of the trouble. It will be recognized that a belt might be made to run straight with half the idlers "knocked" one way and half the other, but this would be at the expense of increased rolling friction between belt and idlers.
