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 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.

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.

摘要： 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.

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 control system, an arrangement for holding the operating speed of the at least one actuator substantially unchanged. The control system is configured to control the processing plant in such a way that a change of amount and/or quality of material arriving to be processed is recognized and in response to the recognized change of amount and/or quality of the material arriving to be processed, the load of a motor is recognized, and in response to the recognized load of the motor, the running speed of the motor or motors of the mineral material processing plant is increased or decreased so that the operating speed of at least one actuator is held substantially unchanged.

摘要： A vibratory screening apparatus including a support and at least two screen decks arranged one over the other as an assembly. Each screen deck includes a screen frame, a screen and a chamber underlaying the screen surface, an outlet duct for oversized material and an outlet duct for undersized material in communication with the chamber. Mountings are configured for mounting the assembly of the screen decks to the support. A drive support with a motor assembly is configured for vibrating the assembly of screen decks. A feed unit is configured to feed the material to be screened to each screen deck. The feed unit is arranged on the support and configured to be moved between a feed position and a maintenance position. The assembly of the at least two screen decks is resiliently arranged on the support, while the feed unit is non-resiliently arranged on the support.

摘要： A maintenance platform of a jaw crusher having an adapter part that engages a first wear part when in place in a jaw crusher cavity. The platform includes a support part that engages a second wear part when the maintenance platform is in the jaw crusher cavity. The platform further includes a platform part residing between the adapter part and the support part. The platform part has a face section that engages the adapter part and a central section that extends apart from the face section towards the support part. The platform part defines at least two grooves each extending from the central section to the face section. The adapter part joins to the platform part by hand screws or nuts through the grooves. The grooves are shaped such that the platform part is separable from the adapter part after untightening while maintaining in place the hand screws or nuts.

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.
