Abstract
Disclosed is a deflection distributor refitting kit for a roller crusher. According to the disclosure the deflection distributor refitting kit comprises a deflection distributing shaft, thrust rods each having first and second ends and mounts for attachment of the deflection distributing shaft at a 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 arranged to be attached to a movable bearing housing of the roller crusher. Also disclosed is a method for mounting the deflection distributor refitting kit, as well as a roller crusher comprising a deflection distributor.
Claims19
A deflection distributor refitting kit for a roller crusher which comprises a frame and a first crusher roll and a second crusher roll arranged axially in parallel with each other, said first crusher roll being rotatably arranged in and supported by bearing housings which are arranged in the frame, said second crusher roll being rotatably arranged in and supported by movable bearing housings which are arranged to be movable in relation to the frame for varying a gap width between the first and second crushing rolls, and a hydraulic system arranged between the frame and the movable bearing housings and configured to exert a pressure on the movable bearing housings for adjusting the position of the second crusher roll and a crushing pressure between the first and second crusher rolls, wherein the kit comprises:
- a deflection distributing shaft;
- a pair of thrust rods each having a first end and a second end;
- and
- mounts for rotatable attachment of the deflection distributing shaft at a first and a second side of a frame of the roller crusher, wherein the deflection distributing shaft is rotationally attached to the mounts and the mounts are stationary in relation to the frame, and
- a pair of levers each having a first end and a second end, the first end of each of the levers being rigidly attached to one end of the deflection distributing shaft:
- wherein the first end of each of the thrust rods is attached to the second end of a respective lever, and wherein the second end of each of the thrust rods is arranged to be attached to a respective one of the movable bearing housing of the roller crusher,
- wherein each of the thrust rods and the movable bearing housings of the roller crusher are constrained to move simultaneously on each side of said roller crusher in a substantially linear path.
A method for mounting a deflection distributor refitting kit to a roller crusher, the roller crusher comprising a frame;
- a first crusher roll and a second crusher roll arranged axially in parallel with each other, the first crusher roll being rotatably arranged in and supported by first bearing housings which are arranged in the frame, the second crusher roll being rotatably arranged in and supported by movable second bearing housings which are arranged to be movable in relation to the frame for varying a gap width between the first and second crushing roll;
- and a hydraulic system arranged between the frame and the movable bearing housings and configured to exert a pressure on the movable bearing housings for adjusting the position of the second crusher roll and a crushing pressure between the two crusher rolls, the method comprising:
- providing a deflection distributor including a deflection distributing shaft, mounts for rotatably attaching the deflection distributing shaft at the frame of the roller crusher, a pair of levers each having a first end and a second end, and thrust rods each having first and second ends, wherein the levers are rigidly attached to the deflection distributing shaft by their respective first ends and wherein a first end of each of the thrust rods is attached to a second end of a respective lever;
- attaching the second ends of the thrust rods to the movable bearing housings respectively;
- and
- attaching the deflection distributing shaft to the frame by means of the mounts such that the deflection distributing shaft is rotationally attached to the mounts and the mounts are stationary in relation to the frame, such that each of the attached thrust rods and the movable bearing housings of said roller crusher are constrained to move simultaneously on each side of said roller crusher in a substantially linear path.
A roller crusher, the roller crusher comprising;
- a frame;
- a first crusher roll and a second crusher roll arranged axially in parallel with each other, the first crusher roll being rotatably arranged in and supported by first bearing housings which are arranged in the frame, the second crusher roll being rotatably arranged in and supported by movable second bearing housings which are configured to be movable in relation to the frame for varying a gap width between the first and second crushing rolls;
- a hydraulic system arranged between the frame and the movable second bearing housings and configured to exert a pressure on the movable second bearing housing for adjusting the position of the second crusher roll and a crushing pressure between the two crusher rolls;
- and
- a deflection distributor, wherein the deflection distributor comprises a deflection distributing shaft, mounts for rotatably attaching the deflection distributing shaft at the frame of the roller crusher such that the deflection distributing shaft is rotationally attached to the mounts and the mounts are stationary in relation to the frame, levers each having a first end and a second end, and thrust rods each having a first end and a second end, wherein the levers are rigidly attached to the deflection distributing shaft by their respective first ends, wherein the first end of each of the thrust rods is attached to the second end of the respective lever, and wherein the second end of each of the thrust rods is attached to a respective one of the a movable bearing housings of the second crusher roll;
- and
- wherein each of the thrust rods and the movable bearing housings of said roller crusher are constrained to move simultaneously on each side of said roller crusher in a substantially linear path.
