Grain Leg Capacity Calculator
A grain leg, also known as a bucket elevator, is a key part of grain handling systems. Knowing its capacity helps prevent overloads, reduce spillage, and improve efficiency. A Grain Leg Capacity Calculator makes this calculation quick and reliable.
The capacity of a grain leg depends on three main factors: bucket size, number of buckets moved per minute, and how full each bucket actually gets (fill efficiency). This calculator accounts for all these variables to give you accurate capacity estimates.
The calculator supports different grain types with their specific bulk densities, ensuring accurate calculations for corn, wheat, soybean, barley, oats, and rice. You can also input custom densities for other grains or special conditions.
Grain Capacity Calculation Formulas
Standard Agricultural Capacity Calculations
Basic Capacity Formula
Capacity = Bucket Volume × Buckets Per Minute × Fill Efficiency
Fundamental calculation using bucket volume, movement rate, and actual fill percentage to determine throughput.
Weight-Based Capacity
Weight Capacity = Volume Capacity × Grain Bulk Density
Converts volume capacity to weight by multiplying by the grain's specific bulk density (kg/m³ or lb/bu).
Speed-Based Calculation
Buckets Per Minute = (Belt Speed ÷ Bucket Spacing) × 60
Calculates bucket movement rate from belt speed and bucket spacing, then converts to per-minute rate.
These formulas provide accurate capacity predictions for various grain handling systems and elevator configurations.
Grain Capacity Calculation Examples
Common Grain Elevator Capacities
| Bucket Volume | Buckets/Min | Grain Type | Capacity (bu/hr) |
|---|---|---|---|
| 0.8 L | 120 | Corn | 1,370 |
| 1.2 L | 100 | Wheat | 1,450 |
| 1.5 L | 90 | Soybean | 1,520 |
| 1.0 L | 110 | Barley | 1,210 |
These examples assume 85% fill efficiency. Actual capacity may vary based on grain moisture, elevator condition, and operating parameters.
