The Snyder Industries Flowmaster Dry Hopper Bin Tank holds 450 gallons — 60 cubic feet — of dry, free-flowing material and drops it out through a steep 45-degree cone bottom. It stands 86 inches tall on a 45 by 48 inch footprint, weighs 352 pounds empty, and is molded in white polyethylene by Snyder in Lincoln, Nebraska. If you have been searching "450 gallon" hopper or "Snyder Industries tank" options and need a bin that discharges cleanly by gravity, this is the Flowmaster built for exactly that job.
Will it carry your material?
Start with the design ceiling: Snyder rates this tank to a 1.9 specific gravity, which sets a maximum rated contents weight of 7,131 pounds. Turn that into a go/no-go check — 1.9 SG works out to roughly 118 pounds per cubic foot, so any dry material with a bulk density up to about that figure fills all 60 cubic feet within rating. Weigh a known volume of your product and compare before you order. The 3,753-pound figure some buyers ask about is only a full water load for cleanout or hydro-test, not your working limit. The tank is rated to a 120 F / 48 C maximum service temperature, so no hot-fill and no exothermic material without derating, and it carries molded design-standard marks 2285 and 2282.
Discharge, cone, and ports
The 45-degree cone is the whole point: it is steep enough to keep most dry granular and powdered materials moving toward the outlet without bridging or ratholing. The 2-inch outlet and 12-inch lid are the molded ports on this tank — outlet fittings, gaskets, and slide or butterfly discharge valves are quoted separately, so call 866-418-1777 and we will spec them to your equipment. Confirm your material's flow angle against the 45-degree cone before you order, and check the technical drawing on this page for the cone geometry, outlet, and lid placement.
Sizing and stand
Use the Tank Sizing Calculator and Tank Sizing Guide to match the 60 cubic foot volume to your batch or storage cycle. Because a loaded bin can approach 7,131 pounds on a compact 45 by 48 inch footprint, the support structure matters — a hopper bin is typically set on a stand or elevated frame so material discharges into equipment below, so size that structure for the full loaded weight. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the load framework if the stand lands on a slab.
