Abstract: An adjusting apparatus of a feed opening of a crushing chamber of a crusher includes one or more adjusting parts arranged in connection with the feed opening, which one or more adjusting parts is/are movable during crushing for adjusting a flow area of material which is to be crushed and is flowing through the feed opening to the crushing chamber. The front edges of the adjusting parts form a unitary flow opening, the flow area of which is adjustable by moving one or more adjusting parts. An adjusting system includes the adjusting apparatus for a feed opening of a crushing chamber of a crusher. A method for adjusting a pressing crusher or a crushing plant suitable for mineral material crushing. A method for avoiding a start peak of a crusher. A method for limiting power intake and/or crushing pressure of a crusher.

Abstract: A cone crusher having a frame, an outer blade adapted to be locked to the frame, an inner blade eccentrically and vertically movable relative to the outer blade, and the inner blade and the outer blade define there between a crushing chamber, a main shaft which is stationary relative to the frame, an eccentric bearing-mounted on the main shaft, a support cone on which the inner blade is arranged, and an adjustment shaft by means of which the support cone is vertically movable from below. A hollow space is arranged inside the main shaft, the adjustment shaft is arranged to the hollow space, a load cylinder is arranged to a lower end of the main shaft which load cylinder comprises an adjustment piston acting to a lower end of the adjustment shaft, a pressure medium supply is arranged to a pressure volume under the adjustment piston for moving vertically the adjustment shaft, and a lubricant supply is arranged above the adjustment piston for directing lubricant via the hollow space to targets to be lubricated.
