Abstract:
In the present invention, a controller for a crushing system comprises a gyratory crushing machine and a feeding machine. The controller is provided with a processing circuit, wherein the processing circuit does the following: acquires a load index directly or indirectly representing a crushing load on the gyratory crushing machine; calculates a particle size ratio in which a production volume of a product that is within a prescribed particle size range as obtained from a crushed product which has been crushed by the gyratory crushing machine is represented as a ratio relative to a prescribed reference production volume; generates a load index target value on the basis of the acquired load index and a correlation between the load index and the particle size ratio; and generates a control command value from the load index and the load index target value.
