High-Performance Finishing Screen
Sandvik QA451 Doublescreen
The Sandvik QA451, the fist evolution of the Sandvik QA Series products and Doublescreen technology. Sandvik QA451 offers you unrivaled throughput and control.
Exceptional Flexibility and Maximum Throughput
The Sandvik QA451 is a formidable solution with two inline 3 x 1.5 m (10 x 5 ft) screen boxes, which provide you with ultimate flexibility and control. The first screen performs as a fines extractor, whilst the second screen performs as a grader. Two processes combined on one plant, offering exceptional flexibility and massive throughput.
We have designed Sandvik QA451 to work in closed circuit with our tracked crushers, and you can optimize the feeding position to upstream units with the fourth hydraulic conveyor.
To provide ultimate flexibility Sandvik QA451 can also work as a stand-alone screening and stockpiling system. In this mode the unit can produce four sized products with fifth oversize material scalped off at the grid. Safety features like full radio remote-control, two-speed tracking and hydraulically folding walkways are included as standard.
Other models within this range of screens include Sandvik QA335 and QA441.
