The work examines improving the efficiency of the wet self-crushing mill by modernizing the face lining design. High wear of lining elements under the intensive influence of ore-spherical mixture leads to a reduction in service life and an increase in operating costs. Based on the analysis of the operation of the MMS 70×23 mill, a new lining with ribbed, cellular-shaped sectional plates has been developed, ensuring uniform load distribution, improved self-lining, and reduced abrasive wear.
