Method for controlling a crusher having a crushing tool and a vibratory conveyor

Abstract

A method for controlling a crusher having a crushing tool and a vibratory conveyor (1) having a drive (5), includes capturing bulk material (2) in a capture region (4) using a sensor (3). So that, in the case of grains with an inhomogeneous grain size distribution, even large grains can be crushed with a constant crushing result without a risk of the crusher being damaged, an effective diameter deff, which results from the largest diameter dmax and the direction (9) thereof, transverse to the conveying direction (8) of a grain of the bulk material (2) is determined as the controlled variable in the capture region (4). If the effective diameter deff exceeds a predefined power threshold value, the power of the crushing tool is increased and/or, if the effective diameter deff exceeds a predefined switch-off limit value, the drive (5) is switched off.

Dependencies are inferred from the claim text.
