2. Description of the Related Art Conventionally, the tooth plate of this type of rotary crusher is
In order to improve the biting of the processed material, for example, as shown in FIG. 12 showing a mantle of a cone crusher, a cone cone 11 having a cylindrical inverted cone shape and a crushing chamber 12 having a wedge-shaped cross section are used to form a crushing chamber. A grooved tooth plate is provided with a large number of grooves 14 in the same direction as the generatrix on the outer peripheral surface of the mantle 13.

However, the tooth plate of the conventional rotary crusher, particularly the mantle, has a frusto-conical shape, and the upper portion is thick and the pitch is large in accordance with the basic conditions described above. It is impossible in terms of shape to make the coarse tooth of the tooth, the tooth of which the lower part is fine and the tooth has a fine pitch (drafting angle, strength of molding sand, seizure, etc.), and rather it goes against the basic conditions. That is, the upper part is fine and the lower part is coarse pitch, and a sufficient effect cannot be obtained.

In addition, the conventional grooved tooth plate has the following problems because it is difficult to cast thin and deep grooves in the middle and lower portions. The crushed material 18 is shown in FIG.
As shown in FIG. 17, the object to be pierced (fitted) in the groove 17 is prevented from flowing downward, which leads to a decrease in the processing amount. Since the groove width is wide, the tooth width is relatively small, the crushing surface area is small, the processing capacity sometimes decreases, and the life is short when abrasion is preceded. When the feed size is small, as shown in FIG. 18, the corner portions of the teeth 16 are worn, and if the corners are rounded, it becomes impossible to crush. When crushing high-strength rock, the teeth 16 may fall down. When mud or water is mixed in the processed material, the mud content is stored in the groove 17, which causes abrasion and reduces the processing capacity.

On the other hand, two kinds of members having different wear resistances are alternately arranged in the same direction as the bus bar on the surface layer portion of the tooth plate main body, and when the processed material is crushed, the wear of the member having low wear resistance is caused. A tooth plate that forms a groove is also known (Japanese Patent Publication No. 2-3).
(See Japanese Patent No. 9939), when trying to match the feed size in the lower part of the mantle, the pitch becomes extremely small with respect to the processed material in the upper part.
