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.

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. The main shaft is fixed stationary to the frame such that the lower end of the main shaft extends outside the frame under the frame and that the lubricant supply is arranged from outside to the outside extending part of the main shaft and through the main shaft to the hollow space.

摘要:
A crusher and a method for controlling a crusher comprising a first crushing member and a second crushing member defining a crusher setting of a crushing cavity into which material to be crushed is being fed. The method comprises the step of: measuring continuously instantaneous load on the crusher; recording instantaneous load peaks exceeding a predetermined target level for the load peaks; keeping track of the number of the load peaks exceeding the predetermined target level during a predetermined period of time; and controlling loading of the crusher on the basis of the number of the load peaks experienced by the crusher during the predetermined period of time.
摘要:
Method and device for collecting objects pointing out of the bottom level of seas or corresponding water areas so that the objects are carried from the bottom by using waterflow through an intake opening of the collecting device moving on the bottom of the sea. The objects are removed from the bottom by a removing device. The lowermost part of the removing device moves at the same level with the bottom of the water area or above it. The most suitable way of removing the objects from the bottom is by using water spray, the flow power of which is controlled separately from the flow power of the water in the conveying channel.

摘要:
A crusher comprising at least a main shaft having an axial line and being mounted on the inner frame of the crusher, an eccentric comprising at least a first eccentric bushing and a second eccentric bushing, a first crushing blade, and a second crushing blade. The first crushing blade is fitted to move along an eccentric path, which path can be adjusted by changing the mutual position of the first eccentric bushing and the second eccentric bushing of the eccentric. The second eccentric bushing comprises a gear transmission for rotating the eccentric, and the crusher comprises adjusting means for changing the mutual position of the gear transmission of the first eccentric bushing and the gear transmission of the second eccentric bushing.
