If you have a cone crusher, you must have encountered the problem of iron crushing, and you know the harm of iron and other indestructible objects to the crusher. The maintenance cost is small, but the expensive shutdown cost is a big problem. Although most mineral processing plants have installed filters on the conveyor belt, it is inevitable that there will be fish that slip through the net.

In order to solve this problem, sandvik has developed an electronically controlled release valve. This release valve control system can check the crusher 200 times per minute. Once the crusher encounters iron overload, the release valve will automatically open and immediately lower the spindle, providing instantaneous overload and iron overload release protection to reduce the damage caused by pressure at the peak value.
The automation system will constantly remove the iron problem, so that your production can continue. Currently sandvik.
CH660 and above crushers have this function.
