Sandvikhas released the advanced electric dump valve system which is the quickest tramp iron protection system of any cone crusher available on the market.
With an astonishing sampling rate of 200 times per second of the hydraulic pressure, this state of the art control and hydraulic system reacts instantly to uncrushable objects, such as tramp iron, drill bits, mill balls, excavator teeth, pieces of steel or severe packing of fine material in the crushing chamber.
The design of the Sandvik HydrosetTM system coupled with the electric dump valve system allows for the quick detection and reaction to uncrushable objects thus decreasing the risk of internal damage to the crusher.
