  • torque calculation on a conveyor Mechanical engineering

    May 27, 2008 · I agree with other respondents comments and notes but 30 years experience tells me that total load x 10% friction factor (for roller conveyor only) x line speed gives an accurate enough result for sizing a conveyor drive. One always goes to the next size up anyway!! Consider soft start equipment to take shock load out of chain, sprockets, drive etc
