Fertilizer Pelleting Systems

One of our fertilizer customers came to us with a straightforward need — a single pellet mill line with a reliable feeding system. Their recipe involved 8 ingredients with no existing way to blend them before the mill.

We started by installing a PSM XL feeder and got their single mill line running consistently. The system ran well, made great pellets, and the customer was satisfied.

That's when they came back.

They wanted to scale — a complete 10 bin batch blend line capable of handling their full recipe. The ingredients ranged widely in bulk density, flow characteristics, and moisture content, making consistent blending the central challenge of the project.

We designed a dual ribbon blender system to solve it. While one blender is being loaded and blended — allowing time for moisture equalization between ingredients — the other blender is feeding the pellet mill. Once the active blender empties, they alternate. The result is continuous production without sacrificing blending time or product consistency.

During commissioning we pushed the system to around 6,000 lbs/hr through the pellet mill. The actual limiting factor turned out to be the post-mill assembly which had been designed for 4,000 lbs/hr — so we dialed back to match the downstream capacity. That slower rate actually produced a better overall product for the customer and gave us longer blending cycles. A future upgrade to the post-mill assembly is a straightforward path to unlocking the full system capacity.

One of the most common situations 3MT works with is operators who have capable mechanical people already on the floor but need someone to design the system correctly from the start and make sure startup goes smoothly.

If that sounds like your operation 3MT offers consulting and system design services that give your team exactly what they need — a properly engineered layout, equipment specifications, and a clear plan to build from. You bring the labor and mechanical capability, 3MT brings the system design expertise and the feeding equipment.

Once the system is built 3MT's startup and commissioning services make sure everything runs the way it was designed to. Having the right person on site during first production runs catches problems early, gets your team up to speed faster, and protects the investment you've made in the system.

It's a practical and cost effective way for operations with strong internal teams to get a professionally designed system without paying for full turnkey installation.

Ingredient count, moisture variation, production rate targets, and plant layout all shape how a fertilizer pelleting system needs to be built. 3MT designs around your specific recipe and operation — not a standard template.
