Sandvik QA451
Sandvik QA451 Doublescreen
The Sandvik QA451 is the world’s first triple deck Doublescreen which offers you unrivalled throughput and control. Through years of research, customer feedback, and Sandvik’s extensive experience in the field, we developed this innovative machine which provides you with massive stockpiling capabilities.
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.
Sandvik have designed the 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.
