The crushing teeth are evenly distributed on the tooth roller shaft. When crushing the lump sintered ore, they are in direct contact with the lump sintered ore, which causes rapid wear, poor crushing effect, and short service life; for metal surfacing treatment, the metal surface must be polished to see the metallic luster, and the surface oil, scale, mud, rust and other dirt must be removed.
