 Determining the Length of Auger Needed Click Here For Westfield Auger Calculators Formula for calculating the length of auger required to fill a bin: STEP #1: Determine distance (H) from ground to eave of bin. STEP #2: Add distance from Step #1 to 1/2 of bin diameter (D). STEP #3: Multiply total figure from step 2 by 1.4. STEP #4: The figure determined in Step 3 is the exact length of auger needed. Use the next longer length of Westfield Auger TOTAL FORMULA(H + 1/2D) x 1.4= Auger Length Determining the Flight Speed Needed Gas Motor RPM=3,000    Electric Motor RPM=1,750 TOTAL FORMULA(Top Sprocket/Bottom Sprocket) x (Motor Pulley/Auger Pulley) x Motor RPM = Flight Speed How to Calculate Pulley Size by Percentage STEP #1: Enter current pulley "Diameter". STEP #2: Multiply "Circumference" listed by percentage change, i.e. to lower speed by 20% mulitply circumference by .8. STEP #3: Enter new "Circumference" figure from Step #2, to find new pulley diameter. Circumference Calculator How to Calculate Ground Length Measurement Square the auger length (K) and the auger height (C). Subtract from the squared length (K). The ground length (L) is the square root of this number. TOTAL FORMULAL = √ (KxK) - (CxC) Approximate Auger Capacities (Bushels per hour) WR60 - 1600WR70 - 2400WR80 - 3000WR100 - 4200 to 5000W130 - 6700 to 8000 MK80 - 3900MK100 - 6000MKX100 - 6600MKX130 - 11,000MKX160 - 23,000MKXGULP130 - 11,000MKXGULP160 - 23,000
