Feed Bin Capacity Estimator

Pick a common bin style and diameter, rings or wall height, hopper angle, and a bulk density from product texture or your own measured value — get an approximate product-specific capacity.

How it calculates

Body height = rings × ring height (default 32″ / 0.813 m; alternate 44″ / 1.118 m).
Hopper height = ((body diameter − typical outlet) / 2) × tan(hopper angle). Volume uses a truncated cone (frustum), not a point tip.
Roof uses a typical ~30° frustum to the hatch — included automatically (usually ~5–12% of volume).
Capacity (t) = (body + hopper + roof) m³ × bulk density (kg/m³) ÷ 1000.

Bin style

Legs

Hopper bins only. Does not change capacity — suggests common diameters for that frame.

Product texture

Pick a texture for a typical starting density, or enter your measured value.

Bulk density *kg/m³

Capacity

Choose style, diameter, rings or height, and bulk density.

Estimates only. Default ring height is 32″ (narrow corrugation); 44″ wide-corrugation is available. Capacity is body + hopper + a typical roof cone (≈30°). Leg count applies to hopper bins only. Texture densities are starting points — use measured density when you have it.
