Vertical Shaft Impactors

The Stedman V-Slam™ is the vertical shaft impactor for all your coarse-to-fine crushing needs. It offers significant savings over higher-priced competitive crushers. The V-Slam, with its low horsepower per ton of throughput, minimizes operating costs. 

Our vertical shaft impactors feature multiple rotor configurations for various applications. From open and enclosed rotors to the Stedman Patented Tubular Rotor, each machine is configured to provide customers exactly what is needed for their unique application.

The V-Slam has a wide speed range as well as the highest rotor tip speed allowing a high degree of process control.

The new Patented Tubular Rotor provides many benefits over the standard shoe and anvil designs as well as rock-shelf applications. The easily replaceable and indexable rotor tubes, cut your total operating cost and maintenance time in half, making V-Slam the easiest VSI to maintain and one of the best impact crushers on the market.
