Impact size reduction incorporates striking to pulverize material. The primary types of impact crushers include -- horizontal shaft impactors (HSI), cage mill pulverizers, and vertical shaft impactors (VSI). Each impactor can be further designated as primary and secondary rotor crusher as well as tertiary and quaternary crushers. This particular designation is dependent on which processing stage the equipment is being utilized. Crusher Throughput ProductionFeed enters the crushing chamber and meets the breaker bars or plates propelling feed against the breaker plates resulting in impact reduction. There are no screens or grates holding material inside impact crushers, so material is efficiently processed at high rates for low costs.Secondary Impact Crush ApplicationsLimestoneGravelClay & ShaleFrac SandCoalSlag (Aluminum Dross, Copper, Steel, etc…)Fired ClaysRAP – Asphalt recyclingConcrete without RebarFloor Tile GlassConcrete BlockStone CrusherResidential, Commercial & Paving BricksGranite

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 crusherson the market.Vertical Shaft Impactor ApplicationsLimestoneSand & GravelGlassFerro Silicon & Silicon CarbideAluminum Dross & Other SlagsBurnt MagnesiteTungsten CarbideTrona SulfateBariteBakery WasteZeoliteand much more...Click here for information on retrofitting your existing VSI to the NEW Stedman Tubular RotorGive Your Materials a Spin in our Test Facility VSIThe Stedman Testing & Toll Processing Facility is the place to test your material in our full size VSI.

H-Series™ Impact MillsThe Stedman H-Series multi cage mill is best at pulverizing, grinding, crushing and mixing abrasive and non-abrasive materials – wet, sticky or dry. The H-Series works more efficiently than other types of pulverizer machines and provides a finer, more uniform grind.H-Series cage mills can handle up to 240 tons per hour and are reversible for extended wear life. The H-Series cage mill is engineered and constructed to operate at or near-peak efficiency longer, providing a greater return on capital investment over its life than competing equipment.H-Series Features and BenefitsCapable of producing a variety of product gradations, easily altered by changing the impact mill speedQuick-opening housing for inspection and maintenance allows for minimum downtime for wear part replacement and inspectionInspections typically require only 5 minutes and complete change out of wear components in as little as one hour or less versus 4 hours or more with other millsCompact, unitized construction, occupies up to 45% less floor spaceReversible DesignProvides optimum utilization of crushing componentsImpact Mill Applications:AglimeAgricultural GypsumRoof & Floor TileClay & ShaleCoalFertilizerSaltsBreak Into Your New Cage MillThe Stedman Testing & Toll Processing Facility is the place to test your material in our full size equipment.
