*Capacities for 6'-9' (1.83m - 2.7m) diameter tanks are calculated at 40 lbs. per cubic foot with no compaction and to full cubic foot capacities. Capacities for 12'-15' (3.66m - 4.57m) diameter tanks are calculated at 45 lbs. Per cubic foot with 5% compaction and a 27 degree angle of repose.

6', 7' and 9' (1.83m, 2.13m and 2.7m) diameter tanks are designed for the storage of free-flowing material having a density of no more than 40 lbs. Per cubic foot. 12' and 15' (3.66m and 4.57m) diameter tanks are designed for the storage of free-flowing material having a density of no more than 45 lbs. Per cubic foot.

Experience has proven that many bulk feed materials have unpredictable storage characteristics. It is absolutely necessary to install an appropriate agitator in feed tanks storing soybean meal, cotton seed meal, hot feeds and other products not considered as free-flowing materials.
