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.
