Tooth roller of titanium sponge crusher and crushing method

The invention provides a tooth roller of a titanium sponge crusher and a crushing method. According to the invention, a plurality of tooth rings of the tooth roller are distributed on a shaft in a staggered manner, and circumferentially positioned through keys, and transmit torques, one sides of the plurality of tooth rings are axially positioned through check rings, and the check rings are fixedly connected on the shaft through lock bolts. The crushing method comprises the following steps: (a) arranging the tooth rollers of two titanium sponge crushers in a staggered manner, wherein the plurality of tooth rings of the tooth rollers adopt the rectangular pyramid form; (b) arranging the tooth rollers of the two titanium sponge crushers in a staggered manner, wherein the plurality of tooth rings of the tooth rollers adopt the pyramid form; and (c) arranging the tooth rollers of the two titanium sponge crushers in a staggered manner, wherein the plurality of tooth rings of the tooth rollers adopt the pyramid form. The tooth roller of the titanium sponge crusher can be used for crushing all hard plastic materials, and solves the temperature rise problem and the material adhesion problem of the material, so that the crushing efficiency is greatly improved, and the tooth roller is particularly suitable for replacing existing components for crushing the hard plastic materials.
