The field-proven, Stedman Grand Slam secondary impactor will give you years of dependable and profitable service. Innovative features make it superior in performance to any type any of its kind today. These are available in 12 low maintenance, minimum downtime models with interchangeable breaker bars, breaker plates and side liners for all models.

Design simplicity offers safe and easy access for breaker bar replacement and unexcelled access to all other areas of the crushing chamber. The front opening feature eliminates need for a crane. If preferred, Stedman also offers a rear opening housing on all models.

Unexcelled in throughput

The feed enters the primary crushing chamber and meets the breaker bars which impel the feed against the front breaker plate. This action and the collision of material against new feed results in impact reduction. Material is sufficiently reduced in the primary chamber and passed by the front breaker plate, entering the secondary chamber for final reduction. Breaker plates are shaft suspended at the front and from a spindle in the rear, allowing for continuous gap adjustment as wear progresses and assuring superior product control.

This impact crusher has a multi-turn breaker bar for extended life before change out and provides years of dependable service. The features of the Grand-Slam deliver unmatched throughput of any competitive machine on the market, making the Grand-Slam highly economical.
