[0017] The present invention will be further described below in conjunction with specific embodiments, and the advantages and features of the present invention will become clearer as the description proceeds. However, these embodiments are exemplary only and do not constitute any limitation to the scope of the present invention. It should be understood by those skilled in the art that the details and forms of the technical solution of the present invention may be modified or replaced without departing from the spirit and scope of the present invention, but these modifications and replacements all fall within the scope of protection of the present invention.

[0018] See also Figures 1 to 4 The present invention relates to a grinding wheel, comprising a wheel body 1, a sleeve 2 and a wear-resistant flange 3. The sleeve 2 is detachably installed on one side of the wheel body 1, and the wear-resistant flange 3 is detachably installed on the other side. The wheel body 1 comprises a sleeve 6, an inner ring flange 7 and an outer ring flange 8. An inner ring flange 7 is welded to the periphery near both ends of the sleeve 6, and an outer ring flange 8 is welded to the inner end face of each inner ring flange 7. A shroud 9 is installed between the two outer ring flanges 8. The shroud 9 is coaxially arranged with the sleeve 6 and surrounds the periphery of the sleeve 6. A rib plate 10 is installed between the shroud 9 and the sleeve 6.
