A New Choice for Iron Powder Granulation: Why Granulating Mixer Is Gaining Popularity

2026.7.27  |  CO-NELE

In iron powder granulation, users often struggle with two traditional methods: extrusion granulation requires a preliminary mixing stage, resulting in a lengthy process and a large equipment footprint; spray granulation suffers from high energy consumption and low efficiency, with limited suitability for metal powders. The emergence of the intensive mixer offers a superior solution—it excels at processing metal powders like iron, and its integrated design makes mixing and granulation efficient, precise, and cost-effective.

How Does a Granulating Mixer Granulate Iron Powder?

Using a granulating mixer for iron powder represents an advanced, game-changing process. Operation is remarkably simple:
All iron powder raw materials are loaded into the granulator at once, with the binder and solvent added simultaneously;
Once started, the material undergoes a complete transformation—from powder to slurry, then to solid, and finally into formed granules—driven by high-speed mixing and shearing forces;
The entire process takes only about 25 minutes to yield dry, uniform iron powder granules that are ready for immediate use, eliminating the need for secondary drying or screening (depending on the formulation).

The process integrates mixing, granulation, and even heating functions into a single unit, removing the need to link separate mixers and granulators and truly achieving a "one-step" solution.

Core Advantages: Why Are Iron Powder Companies Switching to Granulating Mixers?

Boosted Efficiency: No need for separate mixers or additional granulation steps; a single machine handles the entire job, significantly shortening production cycles.
Significantly Lower Energy Consumption: Unlike the high thermal energy demands of spray granulation, high-intensity mixers achieve gentle granulation through mechanical force and controlled heating (optional), resulting in lower energy costs.
Superior Granule Quality: The finished granules offer excellent flowability and high strength; they do not shed powder or generate dust, meeting the rigorous requirements of subsequent pressing or sintering processes.
Safety and Reliability: Given the flammable and explosive nature of metal powders, the equipment can be fitted with explosion-proof systems to ensure production safety.

Controllable Heating: Heating functions can be selected based on material characteristics to accelerate the granulation process—ideal for specific formulations requiring temperature control. 

Covering all application scenarios—from laboratory trials to mass production—with ease.

CO-NELE mixing granulators boast a wealth of proven applications in the field of iron powder granulation, serving industries such as soft magnetic materials for inductors and powder metallurgy. They demonstrate exceptional adaptability across the board, handling everything from high-precision, small-batch prototyping to large-scale, continuous production.
Comprehensive Model Range: A complete lineup spanning from 1-liter laboratory-scale units to massive 3,000-liter industrial-grade equipment.
Flexible Matching: Perfectly tailored to your needs—whether for bench-scale tests, pilot trials, or mass production, and regardless of whether your daily output is measured in kilograms or tons.
Say goodbye to the cumbersome processes of extrusion granulation and the inefficiency and high energy consumption of spray granulation. CO-NELE mixing granulators redefine industry standards for iron powder granulation through a combination of integrated processing, high efficiency, superior quality, and enhanced safety.

Working Principle & Core Technology

CO-NELE laboratory intensive mixer is a high-shear forced mixing system for laboratory R&D, batch testing and pilot scale-up. It delivers 3D circulating mixing to homogenize, knead, disperse and granulate dry, semi-dry, plastic and high-viscosity pasty materials with zero dead mixing zones.
As a reliable laboratory intensive mixer for scale up, it supports linear and repeatable data migration from lab trials to industrial production. All mixing parameters including speed, time and material ratio can be directly applied to mass production lines, minimizing R&D costs and shortening material iteration cycles. It serves as a professional pilot to production mixing machine for research institutes and manufacturing enterprises.
Equipped with precision paddles and high-torque drive, this high shear lab kneader eliminates material segregation and uneven granulation, ensuring consistent mixing quality for small-batch formula tests.
