摘要:
A method is described for adjusting the tightness of a wear part fastened to a fixed jaw and/or a moving jaw of a jaw crusher with a tightening device that has a screw fastened at its first end in connection with a wear part located on a first side of the jaw; and a tightening member fastened to a second end of the screw on a second side of the jaw; and a spring arranged between the jaw and the tightening member. The spring is compressed or decompressed with the tightening member; the spring is influenced by at least two moving screws supported by a frame of the tightening member. The length of the spring is changed by rotating the at least two moving screws.

摘要:
A mineral material processing plant and a method for controlling thereof The mineral material processing plant includes at least one motor, at least one actuator, a feeder device, a control system, and an arrangement for recognizing a need to switch off a standby-mode. The control system is configured to control the processing plant in such a way that the need to switch off a standby mode is automatically recognized. In response to the recognized need to switch off the standby mode the running speed of a motor or motors of the mineral material processing plant is raised from a stand-by speed (Rsb) to a process speed (Rf); and the feeding of mineral material into the processing plant is enabled.
