Sandvik introduce new CS550 cone crusher

Sandvik CS550 cone crusher

Latest secondary-stage machine offers advanced automation and maintenance features

LAUNCHED this week at the Conexpo-Con/Agg show in Las Vegas, the new Sandvik CS550 cone crusher is a powerful secondary-stage machine, designed for 700–750-tonnes/h applications, that offers advanced automation and maintenance features for maximum productivity and uptime.

A key goal in any crushing operation is to accomplish more work – essentially the sum of crusher capacity and reduction ratio – in each crushing stage while never losing sight of overall efficiency, and according to Sandvik, the CS550 does just that.

Complementing the first two Sandvik 500-series crushers, the CH550 and CH540, the new CS550 has been designed primarily as a reliable, high-capacity and high-reduction workhorse for the secondary crushing stage in aggregate production applications.

The Sandvik CS550 is said to achieve up to 25% higher reduction ratios compared with similar types of crushers, ensuring a more efficient process in the secondary stage and relieving the tertiary stage of some of its size reduction load, thereby allowing a sharper quality focus.

Furthermore, the recirculating load is reduced by up to 50% with no decrease in the output of high-value product, ie less material goes back into the crusher to be reprocessed. This extends the service life of the wear parts, especially the costly manganese steel used in the crushing chamber.

‘The Sandvik CS550 has a big intake to match the jaw crusher in the primary stage, with the ability to produce large volumes, deliver a high reduction ratio and an excellent end-product shape,’ said Martin Johansson, life-cycle manager for cones and gyratory crushers with Sandvik Mining and Rock Technology.

‘The wide range when it comes to closed-side settings, together with more and bigger throws, gives you extreme flexibility, as the Sandvik CS550 can be set to fit a huge variety of application needs.’

A major competitiveness factor for the Sandvik CS550 is the complete elimination of plastic backing materials in the crushing chamber and substantial improvements in the maintenance ergonomics, including extensive commonalities with other Sandvik cone crushers.

The automatic setting regulation system, which comes as standard with the crusher, optimizes crusher operation for maximum efficiency and adapts to variations in feed conditions by means of continuous liner wear measurement and compensation.

Moreover, Sandvik’s Hydroset system provides automatic hydraulically powered mainshaft positioning and overload protection to permit the passage of uncrushables, whilst the automation and control system offered as standard for Sandvik 500-series crushers ensures optimal capacity and reduction settings for the high-powered equipment.
