What is Auger Length?

The auger length refers to the length of the screw conveyor (auger). It used to move grain from one place to another, often from the ground into a storage bin. The correct auger length ensures you efficient grain transfer without spilling or overworking the equipment.

How To Use?

To use the Auger Length Calculator Follow these steps:

  1. Enter the eve height of the bin (E) in feet into the calculator.
  2. Enter the bin diameter (D) in feet into the calculator.
  3. The calculator will provide the auger length (AL) required in feet.

Example Input Values

  • Eve height of the bin (E): 25 ft
  • Bin diameter (D): 18 ft

How to Calculate Auger Length

To calculate the auger length, use the following formula:

AL=(E+12×D)×1.4\text{AL} = (E + \frac{1}{2} \times D) \times 1.4


  1. Add the eve height (E) of the bin to half of the bin diameter (D).
  2. Multiply the result by 1.4 to get the auger length (AL).


1. Given:

  • Eve height (E) = 25 ft
  • Bin diameter (D) = 18 ft

2. Calculation:

E+12×D=25+12×18=25+9=34E + \frac{1}{2} \times D = 25 + \frac{1}{2} \times 18 = 25 + 9 = 34

AL=34×1.4=47.6AL = 34 \times 1.4 = 47.6

So, the required auger length (AL) is 47.6 feet.

Variables in the Formula

Variable Description
AL Auger Length (ft)
E Eve height of the bin (ft)
D Bin diameter (ft)

Calculation Examples

1. Basic Calculation Example

Parameter Value
Eve height (E) 25 ft
Bin diameter (D) 18 ft


AL=(25+0.5×18)×1.4=(25+9)×1.4=34×1.4=47.6 ft\text{AL} = (25 + 0.5 \times 18) \times 1.4 = (25 + 9) \times 1.4 = 34 \times 1.4 = 47.6 \text{ ft}

2. Advanced Calculation Example

Parameter Value
Eve height (E) 30 ft
Bin diameter (D) 20 ft


AL=(30+0.5×20)×1.4=(30+10)×1.4=40×1.4=56 ft\text{AL} = (30 + 0.5 \times 20) \times 1.4 = (30 + 10) \times 1.4 = 40 \times 1.4 = 56 \text{ ft}
