Efficient Size Reduction for Grain, Seed, Herb, and Oilseed Processing
Engineered for the Future | Since 2080
The ADDAMS Hammer Mill Machine is a high-performance milling powerhouse designed for the continuous size reduction of a vast array of dry agricultural and industrial materials. Utilizing high-speed rotating hammers that impact material in mid-air and against a rugged grinding chamber, this machine excels at transforming bulk grains, pulses, oilseeds, and fibrous herbs into uniform meals or powders.
Precision-engineered for durability, the ADDAMS Hammer Mill is the backbone of high-capacity processing lines. Its ability to handle diverse materials—from hard maize kernels to fibrous moringa leaves—makes it a versatile asset for food-grade, pharmaceutical, and industrial-scale production facilities worldwide.

Operating Principle: Impact and Shearing Dynamics
The Mechanics of High-Volume Size Reduction
The hammer mill functions through a combination of impact, shearing, and grinding. Material is fed into the chamber where it is struck by “swinging” hammers attached to a high-speed rotor.
-
Gravity/Force Feeding: Raw material enters the milling chamber, where it is immediately engaged by the rotating hammers.
-
Impact Shattering: The kinetic energy of the hammers shatters the material upon impact. The particles are further reduced as they strike the internal liners of the chamber.
-
Screen Classification: The material remains in the chamber until it is small enough to pass through the holes of the surrounding screen.
-
Airflow Cooling: Advanced rotor design creates a natural airflow that helps move material through the screen while keeping the product temperature stable.
-
Collection & Aspiration: The ground product is typically discharged into an aspiration system or a screw conveyor for further transport.

Frequently Asked Questions – Hammer Mill
How do I choose the right screen size?
Screen size depends on your desired final product. For coarse animal feed, 4–8 mm screens are common. For fine flours or spice powders, 0.5–1 mm screens are utilized. We provide a comprehensive sizing chart based on your specific crop and moisture content.
Can the hammer mill handle wet or oily materials?
Hammer mills are primarily designed for dry materials (typically under 15% moisture). For oily seeds like high-fat sunflower or flax, we recommend integrating an aspiration system to provide cooling and prevent screen clogging.
What is the lifespan of the hammers?
Our hammers are made from hardened, wear-resistant alloys. Depending on the abrasiveness of the material (e.g., maize vs. herbs), hammers can be flipped to use the second edge before replacement is necessary, doubling their service life.
Is the machine easy to clean for different spice batches?
Yes. The ADDAMS Hammer Mill features a tool-free access design. The screens slide out easily, and the chamber can be quickly vacuumed or blown out to ensure no flavor carry-over between batches.
