The impactor works by front end loading buckets of material into the hopper inlet of the machine and crushing the oversize material with an internal rotor.  As the internal rotor of the machine is spinning the undersize material sifts through the gaps of the rotors.  The rotor gaps are adjustable based on the lump sizes that need to be retained in the preliminary chamber for size reduction.  The oversize material is crushed through the preliminary breaker bar and moves to a secondary breaker bar with a closer clearance that continues the size reduction.   The machines rotors are available with breaker bar configurations in 2-row, 3-row, and 4-row, which are mounted on an oversized full-length shaft with taper lock elements between the shaft and the end discs.  The rotor construction is heavy-duty, open disc, welded, stress relieved, and statically balanced.  The 2” thick liners of the machine are interchangeable.  The interior of the machine can be accessed easily, when shut-off, through the hinged inspection doors.

  • The impactor can handle feed size material up to 40”.
  • Impactor  machines have proven to achieve reduction ratios up to 30:1.
  • Impactor models range in throughput capability of 5 to 1,200 TPH.
