## how to calculate the speed of a hammer mill

### Common Formulas for Milling Operations - Speed, Feed, SFM

Milling Formulas. Speed (RPM) = (SFM x 3.82) / D. Feed (IPM) = RPM x FPT x Z. SFM (Surface Feet per Minute) = (RPM x D) / 3.82. IPT (Inches per Tooth) = (IPM / RPM) / Z. MRR (Cubic Inches per Minute) = IPM * WOC * DOC. AFPT (@ less than 1/2 dia. WOC) = IPM x sqroot of (D / WOC) HP (Horsepower Consumption) = MRR x mf. mf - steel = 1.

Learn More### How to Calculate Speed Based on Wheel Speed & Tire

Calculate the speed per minute by dividing the wheel speed by the tire revolutions per mile. For example, if the wheel speed is 300 rpm, the example tire is moving at 0.446 miles per minute. Multiply the miles per minute speed times 60 to convert the speed to miles per hour (mph).
