Abstract
In an impact crusher, a rise of an advancing-retracting portion () of a gap adjuster () caused when a rebound plate () touches a rotor () or the rotation amount of the rotor () is detected to determine a zero-point position of the rebound plate () is determined based on the detected result, so that the zero-point position can be securely determined since it is not necessary to touch and vibrate the rebound plate with the rotor rotating at a high speed, and since the rebound plate () is not vibrated, the zero-point position can be securely determined without being influenced by the abrasion of the rebound plate () and the impact plate (), thereby accurately adjusting gap (C).
