SpanishSandvik QA240 (Extec S-4) Screen
Based upon the world leading QA340, the QA240 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 QA240 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 QA240 encompasses such features as:
- Spreader plate - this is of unique 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
Also available with optional:
- Remote Control
- Shredder Box
- Vibrating Grid
