Efficient and High-Capacity Size Reduction for Every Material from Coarse to Fine
Our advanced Hammer Mills are engineered to reduce an exceptionally wide range of materials from coarse pieces down to fine particles (up to 200 mesh) quickly and efficiently. Whether you process friable, non-friable, or fibrous materials, this heavy-duty mill delivers maximum output with minimum energy consumption, per kilowatt/horsepower.
Material enters through a large, obstruction-free feed opening at the top. Inside, heavy-duty hammers rotate at speeds up to 270 MPH (3,600 to 24,000 ft/min). The extreme centrifugal force shatters materials in mid-air and smashes them against hardened breaker plates until they are small enough to pass through the perforated bed screen. Finished particles cleanly exit through the lower outlet via gravity or vacuum collection.
Key Technical Features
Robust & Vibration-Free:
- Built with a heavy-gauge, welded steel housing to maintain perfect alignment.

Dust-Tight Operation:
- Precision-machined mating surfaces ensure a completely dust-tight seal during operation.
Maximum Versatility:
- The hammer arrangements and screen sizes (from 0.8 to 76 mm) can be fully customized to optimize performance for your specific material.
- You can easily swap a section of the breaker plate for an extra bed screen, increasing the total screen area to 270° for maximum production rates.
Flexible Options:
- Choose between carbon steel or stainless steel construction.
- Power ranges from 50 to 250 HP to match your production scale.
- From variable speed drives and rotational automated sensors to pre-crushers and integrated blower assemblies, it tailors the system to your automated production line.
Easy Maintenance & Safety:
- Features a large, easily opened safety-interlocked door and a recessed removable pin system within a hardened steel guard, giving you quick and unhindered access to secondary shafts, hammers, spacers, change screens or breaker plates and allowing your team to replace them in minutes.
- Proprietary “stepped-end” hammers offers 3x more cutting edges than standard square tips. Plus, the 4-way reversible design lets you use all four edges before needing a replacement, drastically lowering your maintenance costs.
Built to Last:
- Designed for heavy-duty, continuous, 24/7 industrial use with extreme impact resistance and structural stiffness. Thanks to the reversible hammer design and hardened steel materials, you get significantly longer service life with less downtime. The rigid housing maintains precise internal alignment even under maximum stress.
Higher Output, Lower Energy Costs:
- Delivers a higher volume of material processed per horsepower/kilowatt than conventional mills, dramatically reducing your operational energy costs.
Optional Features
Material Choices:
- Available in premium Carbon Steel or Stainless Steel with various industrial finishes to meet hygienic or corrosive standards.
High-Velocity Impact:
- Inside the chamber, a high-horsepower motor (ranging from 50 to 250 HP) drives the shaft assembly at speeds between 1,800 and 3,600 RPM.
- Centrifugal force forces the pivoting hammers to stand at a perfect 90° angle.
Multi-Stage Reduction:
- Rotating at tip speeds up to 270 MPH (1,100 to 7,300 m/min), the hammers strike the material in mid-air, shattering it instantly.
- The material is then smashed against hardened breaker plate ridges until it is small enough to pass through the bed screen.
Adjustable Output:
- Interchangable bed screen perforations range from 1/32 to 3 inches (0.8 to 76 mm) to easily control your target particle size.
- For easily reduced materials, a 90° section of the upper breaker plate can be replaced with an additional bed screen, expanding the total screen area to 270° for maximum output.
Custom Hammer Arrangements:
- The type, quantity, and layout of light and heavy hammers can be completely customized to optimize performance based on your specific material.
Detailed Technical Features
Material Infeed:
- Raw material enters through a large, obstruction-free top hopper, ensuring a smooth, continuous feed without clogging.
Patented “Stepped-End” Hammers:
- Equipped with proprietary hardened steel hammers featuring stepped corners. This design provides three times more cutting edges than standard square-cut tips, significantly increasing grinding efficiency.
Dust-Tight Operation:
- Machined mating surfaces between the door and the mill case prevent dust leakage, ensuring a cleaner and safer workspace.
- Finished particles exit through a lower flanged outlet, designed for seamless integration with gravity-fed systems or dilute-phase vacuum collection.
4-Way Reversible Design:
- To minimize downtime and replacement costs, the hammers can be reversed end-to-end and side-to-side, allowing you to fully utilize all four cutting edges before replacement.
Heavy-Duty Construction:
- Built with a heavy-gauge welded steel housing that withstands extreme impacts and high structural loads.
- The dynamically balanced rotor assembly rides on sealed flange-block bearings, ensuring a completely vibration-free operation.
Quick-Access Maintenance:
- Features a large, safety-interlocked door providing unobstructed access to the mill interior.
- The cylindrical breaker plates and lower bed screens slide smoothly within precision-machined channels, held securely in place by the door when closed. This allows for rapid, tool-free screen changes.

The hammers are shown at a 90° angle to demonstrate the high-impact cutting position achieved during operation.
HammerHead™ Model-HM-141-MS, Closed Access Door
Secure mill case door holds the cylindrical breaker plates and bed screens firmly in place. Featuring a full-width top inlet for maximum feed rates and a specialized bottom transition designed for efficient pneumatic material removal.
High-Speed Pulverization
High-speed rotation generates powerful centrifugal force, allowing the free-swiveling hammers to effectively pulverize friable materials into fine particles. Precision bed screens (positioned beneath the rotor) ensure consistent sizing before discharge.

The core assembly features a high-strength alloy steel primary shaft, durable shaft discs, and six quick-disconnect mounting bars. For maximum efficiency, the system utilizes “stepped-tip” hammers that reach a 90° vertical position through centrifugal force during operation (Components are shown in the open position for demonstration only. Integrated safety interlocks ensure the unit never operates while the access door is open).
Customizable Hammer Configurations
Each of the six secondary shafts can be customized with heavy, light, or alternating hammer configurations to perfectly match your specific material characteristics. While high-efficiency stepped hammers are standard, optional square-tip hammers (shown) are also available to meet specialized processing requirements.
