Africa Cement ball mill for sale

Cement mill known as cement mill, cement mill, cement ball mill. Cement mill in the course will be a variety of failures, wear problems which can not be ignored, if not enough attention will result in shortening the life of the ball mill, the wear mechanism of cement mill in the end what is it?

Africa Cement ball mill for sale

Cement mill main wear mechanisms:
1, deformation and wear: ball and sliding materials and impact each other, in addition to cutting and chipping to withstand wear and tear, as well as deformation and chipping furrow deformation along the edges of the grooves and pits, and metal pushed to the oppressed the outside, and repeated the role of metal under repeated deformation, strain due to fatigue crack, crack propagation, connected to form a sheet from the plow thinning balls fall off the table.
2, brittle flakes: ball in by the impact process, brittle phase cracking, crushing, peeling off from the surface, resulting in wear and tear.
3, fatigue wear: grinding in the mill by repeated movement of the rising phase of sliding and rolling, by repeated shocks in the falling stage, the constant impact of stress, contact stress, the role of shear stress in the ball surface fatigue The cracks parallel to the surface of the extension, and extending peeling layer formed on the surface. As nucleation on the surface of the casting defects, extended the lead to macroscopic fatigue spalling.
4, cutting and chipping wear: ball relative sliding movement in the rising phase of the mill with the material, the material is hard component cutting out deep groove ball softer material on the cutting relatively shallow, at a certain the angle of the contact material, the material of the ball resulting in local chiseling wear, chipping pit is formed.
