The utility model relates to an ore sieves broken all -in -one in advance, including the tup rotor, adjustable crushing shell, arrange the material double -edged fine -toothed comb, the tup rotor, adjustable crushing shell, it all installs on the casing to arrange the material double -edged fine -toothed comb, still install 3 piece at least screening conveying rollers side by side on the casing, the axis parallel coplanar that just all is located of each other of screening conveying roller, this plane is parallel or slope with the horizontal plane, the outward flange of cross section of screening conveying roller many big curvature radius curves and many the little curvature radius curves alternative closed pitch arc of connecting the full evagination that forms in proper order of serving as reasons, the big curved curvature radius of curvature radius is greater than the curved curvature radius of little curvature radius, and in big curvature radius curve and the curved junction of little curvature radius, the tangential direction of the two is unanimous. The advantage is: this patent improves work efficiency realizing can also realizing treating to smash material and the screening in order to smash the material when the material is carried.
