Ultramax® Impactors

The Eagle Crusher UltraMax® Impactors were developed for the recycling industry to process concrete with the toughest, high volume, steel rebar with ease. Other HSI impactors, many with open rotors, are designed for the aggregate industry and are unable to handle steel contaminates. UltraMax® impactors ensure versatility, reliability, and durability in aggregate, asphalt and all other applications.
