Roller crusher, a method for monitoring physical conditions thereof, and a refitting kit

A deflection distributor refitting kit for a roller crusher including a frame and movable bearing housings that support a movable roller on the frame, the deflection distributor refitting kit comprising:

• a deflection distributing shaft;
• thrust rods each having first and second ends and mounts for attachment of said deflection distributing shaft at a first side and a second side of the frame of the roller crusher, wherein a first end of each of the thrust rods is attached to the deflection distributing shaft via a lever, and wherein a second end of each of the thrust rods is configured to be attached to one of the movable bearing housings of the roller crusher, wherein the deflection distributor refitting kit further comprises:
• at least one load sensor configured to detect material load in the deflection distributor refitting kit;
• and
• at least one positioning sensor configured, when mounted on the roller crusher, to detect a parameter pertaining to a distance between a first point and a second point of the roller crusher wherein at least the first point is defined on the deflection distributor refitting kit or on one of the movable bearing housings.
