HOW DOES AN IMPACT CRUSHER WORK?
High-Speed Impact Creates Efficient Size Reduction
An impact crusher breaks material by applying rapid, repeated force rather than squeezing it between compression surfaces. Feed enters the crushing chamber and meets a high-speed rotor. Breaker bars accelerate the material toward heavy-duty aprons or breaker plates, where additional impacts continue the reduction process until the material can exit at the required size.
This process can produce high reduction ratios and a well-shaped finished product, particularly when the feed is friable. Horizontal shaft impactors are commonly used for primary and secondary reduction, while vertical shaft impactors are frequently selected for fine crushing, manufactured sand, and product shaping.
Is Impact Crushing Right for the Material?
Impact crushing is most effective when the material fractures before it bends or deforms. Hardness alone does not determine suitability; abrasion, moisture, feed size, required gradation, and acceptable wear cost must also be considered. Highly abrasive materials may be better served by compression equipment even when they are technically friable.
IEG and MAB Equipment can coordinate application review and Stedman testing to help determine whether an impact crusher, cage mill, or another size reduction method is the best fit.
MEGA-SLAM™ PRIMARY HORIZONTAL SHAFT IMPACTOR
Heavy-Duty Primary Reduction for Large Feed

Flexible Rotor Configurations
The V-Slam can be configured around the material and the desired crushing action. Application review helps determine rotor style, speed, wear materials, feed size, and supporting equipment so the VSI produces the required product without unnecessary recirculation or wear.
STEDMAN CAGE MILLS
Controlled Impact Reduction for Wet, Sticky, or Dry Material
Stedman cage mills reduce material through repeated pin impact inside concentric rotating cages. Feed enters near the center of the machine, where successive rows of pins accelerate and fracture the particles. The number of cage rows, pin arrangement, rotational speed, and direction can be selected to achieve the required reduction and product consistency.Because cage mills rely on impact and can operate without the discharge screens used in many hammer mills, they are well suited to a range of agricultural, aggregate, mineral, fertilizer, coal, and industrial applications, including materials that may be wet or sticky.
Common Applications
- Agricultural limestone
- Coal and energy materials
- Fertilizer and soil amendments
- Industrial minerals
- Sand and gravel
- Aggregate fines and tertiary reduction
- Mixing and controlled pulverizing
Key Benefits
- High reduction potential in properly matched applications
- Two-, four-, and six-row cage configurations
- Consistent, controllable product sizing
- Ability to process many wet or sticky materials
- High-capacity production
- Reversible or adjustable configurations on selected series
- Rugged construction with replaceable wear components
Engineered Around the Material
No single cage configuration is right for every feed. Moisture, abrasiveness, bulk density, incoming top size, production rate, and target fineness influence the proper machine and cage arrangement. IEG works with Stedman to evaluate these factors and recommend a cage mill suited to the process.
CUSTOM PORTABLE CRUSHING PLANTS
Stedman Crushers Integrated with TCI Portable Chassis
IEG can combine Stedman impact crushing technology with TCI Manufacturing’s custom portable chassis and plant engineering. Mega-Slam, Grand-Slam, and V-Slam machines can be incorporated into a portable system with the structures, conveyors, access platforms, and material handling components required by the application.Instead of adapting production goals to an off-the-shelf frame, the portable plant can be planned around crusher size, feed method, discharge height, transport requirements, maintenance access, electrical needs, and downstream equipment. The result is a coordinated system supported by one experienced equipment team.

STEDMAN MACHINE COMPANY EQUIPMENT FAQ
Q1. What Stedman equipment does IEG offer?
IEG, through its MAB Equipment division, supplies and supports core Stedman size reduction equipment for aggregate, mining, recycling, and industrial applications. Featured equipment includes Mega-Slam primary HSIs, Grand-Slam secondary HSIs, V-Slam VSIs, and Stedman cage mills. IEG can also integrate selected Stedman crushers into custom TCI portable plants.
Q2. What is the difference between the Mega-Slam and Grand-Slam impactors?
The Mega-Slam is a primary horizontal shaft impactor designed to accept larger raw feed and perform the first stage of reduction. The Grand-Slam is a secondary HSI used to refine intermediate material, control gradation, and produce a cubical finished product. Feed size, capacity, and required output determine which machine and model is appropriate.
Q3. When should I consider a V-Slam VSI?
A V-Slam is commonly considered for fine crushing, manufactured sand, and applications where product shape or a tighter particle-size distribution is important. Rotor configuration, operating speed, wear materials, and feed preparation should be selected around the specific material and finished-product requirement.
Q4. What is the difference between a cage mill and an impact crusher?
Both use impact energy, but they apply it differently. An HSI or VSI uses a high-speed rotor to accelerate material against breaker surfaces or other material. A cage mill moves feed through concentric rows of rotating pins for repeated impact and controlled reduction. Cage mills are often used for finer products and can be effective on many wet or sticky materials.
Q5. Can Stedman equipment process wet or sticky feed?
Suitability depends on the machine and the material. Many cage mill configurations can process wet or sticky feed because they do not rely on a discharge screen. Impact crusher performance can be affected by excessive moisture or buildup, so the feed should be reviewed before equipment is selected. Testing may be recommended when material behavior is uncertain.
Q6. Can Stedman test my material before I purchase equipment?
Yes. Stedman operates a full-size testing facility and maintains more than 10,000 historical material test reports. Testing can help evaluate reduction performance, capacity, power requirements, wear considerations, and achievable finished product before a final equipment recommendation is made.
