REGENERATED CUTTING BLADE AND SHEARING CRUSHER

摘要

The present invention efficiently regenerates a cutting blade by reducing the cost and labor therefor. A cutting blade (105) is provided with a fixing part (125) and a blade part (127) that projects outward from the fixing part (125). The blade part (127) has a distal end edge part (109) pointing in the rotation direction, and side edge parts (110) on a side-surface outer edge part that includes the blade part (127). The distal-end edge part (109) and the side edge parts (110) are regenerated by build-up welding, and have three build-up welds (111, 112, 113) formed on the side surfaces by regeneration. The build-up welds (111, 112, 113), which extend from the side edge parts (110) toward the center of rotation or toward the central direction, prevent crushed material from slipping through.
