L & J Industries Charles City Iowa Free-Flow Supports have approximately 1/3 more steel than other floor supports.

Estimated Capacities of Level Full Cylindrical Bins. Based on 0.8 bu = 1 cu. ft. Weight of bin contents varies by actual material density, packing and bin surface configuration.

TO ESTIMATE BIN CAPACTY: DEPTH X DIAMETER X DIAMETER X 0.628
Example of 27' bin with 16' grain depth: 16 X 27 X 27 X 0.628 = 7325 Bu.

TO ESTIMATE BIN PEAK FILL CAPACITY: DIAMETER X DIAMETER X DIAMETER X 0.056
Example of 27' bin: 27' X 27' X 27' X 0.056 = 1102 Bu.

Free-Flow Floor Supports are stronger!

TO ESTIMATE BUSHELS REMAINING IN BIN AFTER GRAVITY UNLOAD: DIAMETER X DIAMETER X DIAMETER X 0.11
Example of 27' bin: 27 X 27 X 27 X 0.11 = 2165 Bu.

Free-Flow Floor Supports have approximately 1/3 more steel than other floor supports!

TO ESTIMATE BUSHELS IN A PILE: DIAMETER X DIAMETER X DEPTH X 0.21

Farmers report after changing to Free-Flow Floor Supports, dryer capacity was increased by 15 to 20%!
