Operating company: ESSROC CEMENT CORP.
Description of the Plant
ESSROC CEMENT CORP. inNazarethPA,USA, which belongs to ITALCEMENTI, has ordered from HAZEMAG & EPR GmbH in Dülmen a primary crushing plant for limestone with an average output of 1,000 t/h. The plant replaces an existing system and consists of the apron feeder and the single rotor impact crusher AP-PMH 2022.
The apron feeder with underlying chain scraper conveyor for the spillage material has a variable-speed drive, so that the capacity can always be adapted to operational requirements.
The crusher with grinding path processes feed sizes with a maximum edge length of 1 m into a finished product with 97 % < 100 mm. Here the gap of the impact aprons and grinding path can be adjusted electrohydraulically. The crusher is fitted with a GSK rotor with a diameter of 2,000 mm and a width of 2,200 mm. These robust cast-iron welded rotors are characterised by a particularly high moment of inertia, with which throughput peaks can be processed without difficulty.
