A method for operating a mineral material crusher, a system including a crusher, and a crushing plant. The mineral material crusher, includes a first crushing element and a second crushing element, defining a crusher gap therebetween. The crusher gap is maintained using at least one hydraulic cylinder, the hydraulic liquid pressure in at least one of the hydraulic cylinders is measured and hydraulic liquid is evacuated from the hydraulic cylinder when the hydraulic liquid pressure exceeds a set opening pressure limit. During the crushing process the following steps are repeated: generating, based on the hydraulic liquid pressure measurement, a representative value of a normal hydraulic liquid pressure in the at least one hydraulic cylinder caused by the crushable material in that crushing application; comparing the generated representative value and the set opening pressure limit; and selecting opening pressure limit which is higher than the measured normal hydraulic liquid pressure.
A method for operating a mineral material crusher, wherein the crusher comprises a first crushing element and a second crushing element, defining a crusher gap therebetween, and the crusher gap is maintained using at least one hydraulic cylinder, the hydraulic liquid pressure (PM) in at least one of the hydraulic cylinders is measured and hydraulic liquid is evacuated from the at least one hydraulic cylinder in case the hydraulic liquid pressure in at least one of the hydraulic cylinders exceeds a set opening pressure limit, characterized by repeating during the crushing process the steps:
