Grand-Slam Secondary Impact Crushers

Stedman’s Grand-Slam line of impact crushers are built to handle thousands of materials in wet and dry applications. The crushing action of the Grand-Slam delivers properly sized material the first time through.

The field-proven Grand-Slam secondary impact crusher are available in 14 high-performing, low-maintenance models with interchangeable breaker bars, breaker plates and side liners.

  • High reduction ratios up to 30:1
  • Interchangeable parts
  • Capacities from 5 to 1,600 tons per hour
  • Feed sizes up to 16 inches
  • Allows for one-man switch of breaker bars
  • CE and TUV compliant

Vertical Shaft Impactors

Stedman’s vertical shaft impactors can be used for all your coarse-to-fine crushing needs. VSI crushers offer significant savings over higher-priced competitive crushers. With its low horsepower per ton of throughput, the vertical shaft impactor minimizes operating costs.

Stedman’s vertical shaft impactors feature multiple rotor configurations for various applications, have a wide speed range, and a high rotor tip speed that allows a high degree of process control.

  • Tighter particle size distribution
  • Reversible wear parts reduces downtime by more than 50%
  • Raw feed sizes up to 5"
  • No screens or grates
  • Wide speed range for excellent process control
  • CE and TUV compliant

H-Series Cage Mill

The Stedman H-Series Multi Cage Mill pulverizes, grinds, and crushes abrasive and non-abrasive materials – wet, sticky or dry. The H-Series model works more efficiently than other types of pulverizers and provides a finer, more uniform grind.

Use the H-Series cage mill to crush animal feed, corn, fertilizer and agricultural gypsum.

  • Reliable: Can handle up to 240 tons per hour
  • Durable: Reversible for extended wear and operates at or near-peak efficiency longer
  • Versatile: Can produce various gradations by changing operating parameters
  • Practical: Hydraulically-operated, quick-opening housing allows for easy access for inspection and to service.
  • CE and TUV compliant

F-Series Cage Mill

The F-Series Cage Mill Crusher features a unique flared discharge opening, efficiently reducing the wettest and stickiest of materials without clogging and decreasing downtime for cleaning.

Use the F-Series cage mill crusher to process animal renderings and grains.

  • Flared housing eliminates corners that trap material, reducing clogging
  • Capable of multi-stage reduction
  • Variable mill speed
  • CE and TUV compliant

Full Circle Hammer Mill

In a hammer mill, rectangular pieces of hardened steel are attached to a shaft and rotate at high speed inside the milling chamber. The grain then encounters a changeable screen with a “close tolerance” gap between it and the rotating hammers. Finally, the grain passes through a screen before exiting the mill.

Hammer configuration, rotation speed and screen sizes can be varied to process different grains, and each component can be changed individually.

Use Stedman’s full circle hammer mill to grind corn, wheat, and malted barley.

  • Capacities up to 35 tons per hour
  • Higher throughput due to the greater screen area
  • Compact size means small footprint
  • Easily accessible doors
  • Quick release screens
  • Reversible
  • Externally adjustable intake
