Tracked screen added to Extec range

Extec has launched a new tracked screen - the E7, a heavy-duty track mounted self-propelled open flow screening and stockpiling system. It has been purpose -built for the recycling and quarrying markets.

The E-7 has been developed over the last 18 months through Extec’s R&D programme. Based on in-depth customer and market analysis, the E-7 has been developed in order to deal with customers’ real requirements, which traditional screening solutions are unable to adequately cater for. These include:

  • Screening heavy over-burden at the quarry face
  • Pre-screening/scalping prior to being fed into a crusher
  • Recycling construction and landfill waste
  • Separation of “sticky” aggregate
    Extec reports unprecedented demand for the E-7.
    Key features of this machine include:
  • Heavy-duty hopper adjustable for length and loading height. Capacity up to 10 m3
  • Double-plated apron plate feeder
  • Heavy-duty screen box with high throw and high vibration with an adjustable angle of incline ranging from 10 – 22 °
  • Punched plate, heavy duty mesh, rock fingers or grizzly bars can be fitted to the top deck while heavy duty mesh or fingers can be fitted to the bottom deck

  • Large free flow area from the hopper onto the screen box
  • Large open free flow area from the screen decks to the stockpiling conveyors
  • Rear conveyor which handles the larger sized products is supported by an impact bed which prevents roll-back or lateral movement of material
  • Heavy duty crusher-type chassis.
