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
