s2, placing the grinding roller sleeve in the grinding roller sleeve cavity, and arranging the roller shaft of the grinding roller sleeve opposite to the movable shaft of the hydraulic jack;
s3, mounting a limiting rod on a limiting piece, and matching the limiting rod with the grinding roller sleeve to limit the axial displacement of the grinding roller sleeve;
and S4, controlling a hydraulic jack to drive the movable shaft to move forwards, stopping the movable shaft against the roll shaft and driving the roll shaft to generate axial relative displacement relative to the grinding roller sleeve until the roll shaft is separated from the grinding roller sleeve.
10. The method for controlling a disassembly and assembly tool for a Raymond mill roll sleeve of claim 9, wherein the movable shaft is coaxially arranged with the roll shaft.
