Stainless Hopper Bottom Bins

Hopper bins are designed for dry fertilizer storage with convenient gravity-flow discharge.

Perfect for:

• Dry fertilizer storage: Store bulk dry blends, urea, MAP, DAP, etc.
• Gravity discharge: No augers needed—product flows naturally to discharge
• Blending operations: Multiple bins allow custom dry blend creation
• Protected storage: Keep product dry and contamination-free
• Efficient loading: Fill from top, discharge from bottom

Scale hopper bins are precision weighing systems for dry fertilizer blending operations. They're essential for:

• Custom dry blend creation: Weigh exact amounts of each component
• Batch consistency: Replicate blends perfectly every time
• Inventory management: Track exactly how much product you're using
• Quality control: Ensure precise nutrient ratios
• Regulatory compliance: Document exact blend formulations

They're the heart of professional dry fertilizer blending operations 

We offer hopper bins in:

• 12' diameter (scale hoppers): 65–68 long tons (59–62 metric tonnes) 
• 14' diameter: 89–68 long tons (81-153 metric tonnes)
• 16' diameter: 119–224 long tons (108-203 metric tonnes)
• 18' diameter: 154–289 long tons (140–262 metric tonnes)

Capacity varies based on cone angle (40, 45, or 55 degrees) and overall height configuration.

The wind shelter (optional) protects the scale hopper from wind pressure that could affect weighing accuracy. When you're measuring in increments of pounds for precision blends, even moderate wind can throw off your measurements. The wind shelter eliminates this variable, ensuring consistent, accurate weights regardless of outdoor conditions.

If you're running a commercial blending operation where precision matters, the wind shelter is a smart investment.

The cone angle affects how easily the product flows out:

• 55-degree cone: Steepest angle, best flow for most products, requires most vertical space
• 45-degree cone: Good flow for most products, moderate height
• 40-degree cone: Lowest profile, works for free-flowing materials.

Your product's flow characteristics and site height constraints will determine the best choice. Our team can help you select the right angle, give us a shout.

It depends on the size—see "How do I stand my tank?" in the main FAQ.

Tipping works for most 14', 16' and 18' diameter bins with moderate height Crane required for any bins with a sidewall over 30'. 

Both are excellent grades of stainless steel, but they're formulated for different applications:

304L Stainless Steel is our standard grade and handles the vast majority of fertilizers beautifully. It offers excellent corrosion resistance for common agricultural products like 28-0-0, 10-34-0, and most fertilizer blends. For most farming and ag retail operations, 304L is the perfect choice.

316L Stainless Steel contains molybdenum, which gives it superior performance. It's the right choice if you're storing products with higher salt content, or are near coastal environments where salt air is a factor. The "L" in both grades means "low carbon," which provides additional corrosion resistance in welded areas—especially important for hoppers that have been welded.

Bottom line: If you're storing standard dry fertilizers, 304L is great. If you're working with more corrosive products or harsher conditions, upgrade to 316L. Not sure which you need? Our sales team can help you match the right grade to your products—give us a call at 1-877-956-6843.
