摘要： 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.

摘要： A method for lifting an inner wear part of a gyratory or cone crusher and an inner wear part lifting tool for use with the method. The gyratory or cone crusher has a frame, an outer wear part fixable to the frame and the inner wear part fixable to a support cone of the crusher which outer and inner wear part define a crushing chamber. The inner wear part has an inner surface including a first inner support surface arranged, in a crushing phase, to be supported by a first counter surface of the support cone. In a first phase, a lifting arm of a lifting tool is arranged inside the inner wear part and under the inner surface of the inner wear part. In a second phase, an upper second counter surface of the lifting arm is coupled with a second inner support surface of the inner wear part.

摘要： The disclosure relates to a cone crusher, including a supporting device being arranged inside a cavity of a main shaft of the crusher. The supporting device is arranged to support a crushing head, and to be vertically displaceable for adjusting the width of a crushing gap. The supporting device has an upper portion enclosed by the crushing head, the upper portion being arranged to provide support to the crushing head. A lower portion extends downwards within the cavity of the main shaft, wherein the upper portion and the lower portion have different outer dimensions as defined transverse to the shaft axis. A pressure-active surface is formed at a transition between the upper portion and the lower portion so as to form a variable-volume compression chamber within the cavity below said pressure-active surface.

摘要： A crusher is disclosed having a rotatable eccentric, a main shaft supported to the eccentric, a piston for adjusting the vertical position of the main shaft and an axial thrust bearing between the lower end of the main shaft and the piston. The thrust bearing has an upper bearing attached to the lower end of the main shaft, a lower bearing attached to the piston, and a pressure plate between the upper bearing and the lower bearing. A circular groove or expansion is formed onto the pressure plate. A releasing member is attached to a crusher structure outside of the pressure plate. The releasing member has a circular lip directed to the direction of the pressure plate. Part of the lip is in the groove or above the part of the extension. The releasing member is attached to the piston.
