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.

A method for controlling the operation of a crusher, a mineral material processing plant and a control system. The method including measuring a quantity related to stress to which the crusher is exposed during the crushing of material, determining a deviation value of the quantity related to stress, comparing the determined deviation value to a reference deviation value, and in response to the deviation value differing from the reference deviation value, adjusting a default setting of the quantity related to stress.

A wear part for a mineral material processing apparatus includes an outer wear surface which includes an initial phase wear surface to be put in crushing contact with an opposite wear surface, and an end phase wear surface to be taken vertically into use in the crushing process from under the initial wear surface when the wear is progressing. The wear part includes an end phase wear surface with a protrusion to be put in use when the wear of the outer wear surface is progressing. As a result of the wear part including the protrusion working life of the wear part can be prolonged. A mineral material processing apparatus and a mineral material processing plant.
