The invention relates to a method for determining the layer height of a feed material, which is supplied to a crushing and/or screening plant of a material processing device, wherein a conveyor device is used to convey the feed material in a conveying direction, wherein a sensor array comprising a plurality of sensors is used to determine the layer height of the feed material. A reliable method that can be performed with little effort and without impairing the operation of the material processing device is achieved by the longitudinal axes of the detection volumes of the sensors extending at least partially in and/or counter to the conveying direction.

The invention relates to a crusher plant, in particular a jaw crusher, including a crushing unit for crushing mineral material, the crushing unit comprising a crushing chamber, to which a crusher outlet is assigned, via which crushed material exits the crushing chamber, at least one actuator being provided, by which the opening size of the crusher outlet is adjustable in the event of an overload situation in the crushing unit, in order to discharge faulty material from the crushing chamber, a belt conveyor being provided after the crusher outlet in the material conveying direction, faulty material being transportable by the belt conveyor from the crusher outlet, following an overload situation, toward a transfer end of the belt conveyor, a detection device being provided, by which the overload situation of the crushing unit or an operating change of the crushing unit brought about as a consequence of the overload situation is detected and an overload signal is then generated, and a control device controlling the belt conveyor and/or monitoring the faulty material transported on the belt conveyor by taking into account the overload signal. According to the invention, it is thus possible to restore the operational readiness of the crushing plant quickly and in a simple manner following the occurrence of an overload situation.
