Snyder Industries 58 Cubic Feet 60 Degree Plastic Flowmaster Dry Hopper Bin Tank

The Snyder Industries Flowmaster Dry Hopper Bin Tank holds 58 cubic feet (rated 434 gallons) in a steep 60-degree cone-bottom body built for gravity discharge of dry, free-flowing material. It stands 91 inches tall on a compact 48 x 48-inch envelope, is molded in white FDA-approved polyethylene, and ships empty at 352 pounds. This is a Snyder specialty bin, part of the dry hopper bin tank family, and its geometry is the whole point: the 60-degree cone angle is aggressive enough to keep granular product moving toward the 2-inch bottom outlet instead of bridging or rat-holing.

Will it work for your material?

Check the technical drawing on this page against your headroom and discharge height first. The 48 x 48-inch dimension is the tank envelope, not a free-standing base - a 60-degree cone cannot sit on the floor, so this bin requires a support stand or skirt, and the 2-inch outlet ends up elevated well above grade for gravity discharge into a bag, tote, or auger below. The resin is FDA-approved for direct food contact, which qualifies it for grain, feed, sugar, flour, and similar edible dry solids. The tank carries a specific gravity rating of 1.9, meaning the polyethylene wall is engineered to hold contents up to that density. In practice that gives a max rated contents weight of 6,877 pounds - far heavier than the 3,620 pounds this footprint would see full of water - which is why this bin suits dense dry solids where a standard 1.0 SG water tank would be under-rated. The 12-inch lid handles top loading and inspection, and the maximum service temperature is 120 F (48 C).

The mistake to avoid

Match the tank rating to your actual bulk density, not to volume alone. Because this is a 1.9 SG bin, the limit you plan around is the 6,877-pound contents rating, not the 434-gallon number - overfilling a dense material past that weight is the failure mode these dry hopper bins are specifically rated to prevent. Size the support structure for the loaded cone, not the empty shell; a 352-pound tank becomes a multi-thousand-pound load the moment it is filled, so the stand and pad have to carry the full 58 cubic feet of dense product. Our Tank Sizing Calculator and Tank Sizing Guide help you reconcile cubic-foot capacity against material weight, and the concrete pad sizing guide (ACI 360R-10) covers the foundation under a loaded above-ground poly tank.

Fittings and outlet

The bin comes with the 2-inch bottom outlet and 12-inch lid opening as molded. It does not arrive with a discharge valve or slide gate specced - call 866-418-1777 and we will match a valve or slide gate to your material and flow before it ships, so you are not guessing at the discharge hardware.
