Crushing plant

A crusher plant, comprising:

• a jaw crusher including a crushing chamber having a crusher outlet by which crushed material may exit the crushing chamber;
• at least one actuator configured to adjust an opening size of the crusher outlet to allow faulty material to be discharged from the crushing chamber;
• a belt conveyor configured to convey the crushed material or the faulty material in a material conveying direction from the crusher outlet toward a transfer end of the belt conveyor;
• a load sensor configured to detect an overload of the jaw crusher and to generate an overload signal when an overload is detected;
• and
• a controller configured to receive the overload signal and at least in part in response to the overload signal to control the belt conveyor and/or to monitor a position of the faulty material on the belt conveyor;
• wherein the controller is configured such that following reception of the overload signal the crusher plant is switched to a manual operating state in which an operator of the crusher plant may control the belt conveyor with a manual operating unit;
• and
• wherein the controller and the manual operating unit are configured to provide a restart mode wherein following activation of the restart mode, first the belt conveyor is started up, and subsequently the jaw crusher and then a material feeder which feeds material to be crushed to the jaw crusher are reset.
