    See all results for this questionHow do you calculate screw pitch?How do you calculate screw pitch?Define if the screw conveyor is flat (which is always preferable) or has to be inclined. Determine the correction factor corresponding. Adjust the screw speed so that the capacity of the screw is higher than the requirement. No specific duty for the screw, the pitch is chosen standard, S=0.1 m The calculation gives 17 kg/h for 1 rpm.

  • screw conveyor calculation formula metric

    Oct 08, 2010· The easiest way I have found to derive this whenever I can't remember the formula is to think of it in terms of "distance / revolution" of the screw and convert to a rack and pinion. I do this kind of calc for various machine types as many as 3 or 4 times a week. 4 TPI = .25 inches / revolution.

  • Screw Conveyor Capacity | Engineering Guide

    The actual screw conveyor speed is calculated by dividing the Selection Capacity by the capacity at 1-rpm. 1,873/31.2 = 60-rpm 60-rpm is the correct speed for a 16-inch diameter screw conveyor with cut and folded flights and short pitch for conveying and mixing 333 cubic feet per hour.
