Esmil Screw Compacting Press

Features and advantages of Esmil Screw Compacting Press:

  • Enclosed design with easy access to operating mechanisms.
  • Installation and synchronization with existing equipment.
  • Different diameters screws, depending on the amount and content of screenings: 120 mm, 200 mm, 300 mm.
  • The perforation of the casing is made taking into account the optimal arrangement of the holes for draining the filtrate and wash water.
  • Possibility of reverse movement to eliminate possible jamming.
  • Use of high-strength steel inserts are installed in the housing to protect it from abrasion caused by the screw.
  • The manufacture of screws using a special technology of stretching and forming, which allows precisely maintain a variable pitch in the compacting zone and a constant pitch in the transportation zone.
  • High-precision turning edge processing ensures precise work and stationary movement of the screw.
  • Various types of washing depending on the Customer’s needs: washing of the housing in the compacting zone and in the screenings loading zone, organic matter washing out of screenings.
  • On Customer demand, the press may be equipped with an additional washing system of screenings in the screening loading zone.
  • In case when building area does not allow direct compacted screenings discharge to the container, a discharge pipe can be designed up to 5 m long.
  • For such cases, the discharge pipe can be installed at an angle of 10° to 90° to the horizontal plane and rotated 90° relative to the housing.
  • On demand, the press can be installed on telescopic supports.
  • Possibility for outdoor installation design.
