A very common problem. How do I figure my auger's RPM?
Use these formulas to figure auger RPM.
For straight pulley reduction:
Drive pulley x motor RPM = SUM ÷ driven pulley diameter = auger RPM
For auger with a reduction gearbox:
Drive pulley x motor RPM = SUM ÷ driven pulley diameter = SUM ÷ gearbox reduction ratio = auger RPM
To use the auger RPM you've figured to figure capacity, click here.
