Roller for high pressure roller grinder, roller grinder, and method for assembling a roller for a roller grinder
A roller for a roller grinder, the roller including a shaft and a grinding shell in the form of a tubular sleeve and having an inner face to be retained around the shaft. The roller grinder is characterized in that the shaft includes two shaft parts, each shaft part having a respective inner end portion, wherein the inner end portions are arranged to be positioned facing each other and include coupling portions arranged to couple the inner end portions of the respective shaft parts to each other, thereby forming the shaft. The disclosure further relates to a method for assembling a roller for a roller grinder, the roller including a shaft and a grinding shell in the form of a tubular sleeve and having an inner face to be retained around the shaft.
The present invention relates to a roller crusher having two generally parallel rotatable rollers separated by a gap, and a feeding arrangement for feeding material to the rollers. The roller crusher includes a base frame and a first and a second roller frame section, each of the first and second roller frames sections being pivotably connected to the base frame and arranged for carrying one of the rollers in bearings arranged at opposed ends of each roller. The roller crusher also includes at least one balancing cylinder extending between one of the roller frame sections and the base frame such that when the at least one balancing cylinder is activated, the interconnected roller frame sections will pivot relative to the base frame, thus adjusting the position of the rollers relative to the base frame.

The present invention relates to a roller crusher having a base frame and a roller frame movably connected to the base frame. Two generally parallel rotatable rollers separated from each other by a gap are arranged in the roller frame. The roller crusher further includes a feeding arrangement mounted to the base frame for feeding material to the rollers and at least one balancing cylinder is provided which are connected to and arranged to manipulate the roller frame relative to the base frame such that the position of the rollers relative to the feeding arrangement can be adjusted. Front and rear cheek plates are provided at the roller frame partially covering front and rear end surfaces of one of the rollers and at least partially covering an opening between the feeding arrangement and the two rollers, the cheek plates being fixedly mounted to the roller frame.

Roller crusher, and method of protecting a roller crusher from uncrushable objects
opening the in-feed to the gap, such that material is fed to the gap at an operational in-feed rate. A roller crusher having a protective system for protecting the roller crusher from uncrushable objects is also disclosed.
A bearing arrangement for a roller crusher having a pair of crushing rollers (R), each one including a shaft having end portions, mounted in respective bearing housings carried on a base structure (S) of the crusher, and a median hub portion. The bearing housings of each roller (R) are affixed to a structural frame disposed externally to each roller (R), along one side of the respective roller (R), the structural frame maintaining the bearing housings of each roller (R) rigidly connected to each other. Each bearing housing includes: a base portion affixed to the structural frame and a cover portion turned to the other roller (R) and removably affixed to the base portion.
A stress monitoring system for use in a vibrating unit having first and second opposed sidewall plates includes at least one motion sensor disposed at at least one corresponding monitoring point on each of the first and second plates. The motion sensors are connected to a processor such that simultaneous monitoring data of the monitoring points is provided to the processor for comparing real-time movement of the corresponding monitoring points of the opposed plates.
G01H 17/00 - Mesure des vibrations mécaniques ou des ondes ultrasonores, sonores ou infrasonores non prévue dans les autres groupes de la présente sous-classe
An apparatus includes a shell connection mechanism configured to be actuated between a connected state in which a mechanism is connected to a shell and a disconnected state and an actuator configured to move the first mechanism while the first mechanism is in the connected state to move the shell.
An apparatus includes a mill, a rotary actuator configured to apply torque to the mill, a sensor configured to sense a parameter corresponding to rotation of the mill and a controller configured to generate control signals based upon acceleration of the mill. Rotation of the mill is modified as a result of the control signals.
