THE BRAND NEW INSPIRATIONAL TRIPLE DECK S-7 SCREENER
Extec have launched the ultimate large production screen; the totally brand new - S-7.
The S-7 is based around the revolutionary Doublescreen concept that has taken the screening world by storm. Designed for the aggregate producer who requires large throughput, true mobility and clean gradings, the new S-7 Possesses such features as:
* Screening area consists of two individual 10x5 screen boxes incorporating 3 decks in each screen box, allowing for a more concentrated screen.
* Each Screen box possesses its own separate drive, and each being independently angled to aid the screening process.
* The screen box arrangement presents a massive screening area, yet allows for an incredibly clean product through the independent set up of the two screen boxes.
* An extra side conveyor that enables the S-7 it to produce up to a massive total of 5 product materials.
* Longer, chevron belted side conveyors, in order to feed directly into a cone crusher, and/or possess vast stockpiling capacities.
* Longest tail conveyor in its class for even greater stock piling capacity.
* Faster running belts in order to facilitate high rates of production.
* Patented screen box lift mechanism to ease mesh change.
* New stronger chassis design for the most demanding of environments.
* Longer tracks in order to produce a stable screening platform.

Robotrac
In a worldwide context this is the definitive track mounted scalping screen which employs such a highly efficient screening process it doubles as a grading screen in many applications.
Designed to scalp heaviest of material yet its ability to screen finer sizes is phenomenal for a scalper. Its sheer manoeuvrability on the ledge of a mountain quarry or on the demolition site of a Tokyo 'pencil' building has earned it the reputation of being one of the world's most versatile screens in terms of production and mobility. Key features include:
* Fitted with the world-renowned Extec double deck vibrating grid
* High speed scalping of sticky clay and fines from heavy rock and concrete
* Heavy-duty impact feeder absorbs shock loads and maintains smooth flow of material to the stockpiling conveyor
* Self-propelled and highly manoeuvrable on site
* Remote control operation by excavator operator

E-7
Extec have announced a brand new tracked screen – the E7, a heavy-duty track mounted self-propelled open flow screening and stockpiling system. This revolutionary machine has been purpose built for the recycling and quarrying markets.
The E-7 has been developed over the last 18 months through Extec’s acclaimed 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

S-3
The newest member of the S-Series is a single screen-box screener that uses the same state of the art design technology to construct a screener for today’s requirements.
Perfect for the quarry or recycling operation where durability, production and mobility are paramount. The S-3 encompasses such features as:
* Spreader plate - this is of unique Extec design to spread material across the full width of the screening facility while maintaining the velocity of the material particles
* Chassis - this is of the most modern computer assisted design capable of withstanding the stresses generated by high speed highway towing or track slewing over the roughest of terrain
* Extec's unrivalled high frequency screen-box designed for easy change of screen meshes and unsurpassed screening efficiency

S-4
The Extec Double Screen
Based upon the world leading S-5, the S-4 is designed for operation where the massive throughput of its larger sibling is not required, but there still exists a requirement for precision screening only available from a Doublescreen.
The S-4 produces a huge screening area (at least equivalent to a traditional 16’X5’ (4.8m x 1.5m) screening system) but with to independently adjustable screen boxes for precision screening and massive production.
The S-4 encompasses such features as:
* Spreader plate - this is of unique Extec design to spread material across the full width of the screening facility while maintaining the velocity of the material particles
* Screening facility consists of two individual screening units, each having its own separate drive and each being independently angled
* The split screening facility enables the first screen box to be used as fines extractor even of the most difficult sticky material while the second box operates as a grader. The net result is that the Doublescreen produces grades of material of the most precise specification that we have ever seen from a mobile screening system
* Chassis - this is of the most modern computer assisted design capable of withstanding the stresses generated by high speed highway towing or track slewing over the roughest of terrain

S-5
The Extec Double Screen
The ultimate mobile screening system designed for the truly serious contractor or quarry operator.
The S-5 represents the greatest innovation in mobile screening systems as the S-5 resolves the conflicting principles previously associated with providing larger screening areas on mobile plant.
Massive throughput, mobility and a class leading screening area results in the ultimate profit generator.
The S-5 encompasses such features as:
* Heavy duty tipping grid activated by remote control - this will accept feed from a wheeled loader or excavator. Large hopper with variable speed belt-feeder, which has heavy-duty roller bed and heavy-duty belting
* Two individual screening units, each having its own separate drive and each being independently angled. The throughput of this screening facility parallels that of a conventional screen box of 7.62m long
* Chassis - This is of the most modern computer assisted design capable of withstanding the stresses generated by high speed highway towing or track slewing over the roughest of terrain
