を行うものである。2. Description of the Related Art A centrifugal crusher as shown in FIG. 2 is conventionally known as a device for crushing raw materials such as minerals. Briefly describing this crushing machine, a crushing chamber 11 is defined in a housing 1 which is an outer shell of the crushing machine, and a rotor 2 capable of high-speed rotation in a horizontal direction is arranged in the center of the crushing chamber 11. ing. Raw materials such as minerals are supplied into the rotor 2 and centrifugal force generated by rotation of the rotor 2 causes
The gas is discharged tangentially from a discharge port 21 formed on the peripheral surface of the rotor 2. Then, the released raw material collides with a dead bed 12 made of crushed pieces of raw material accumulated in a ring in the crushing chamber 11 or a steel anvil (not shown).

短くなってしまうため、不経済である。Means for supplying the raw material into the rotor 2 is to form an insertion hole 22 in the center of the upper disk,
The insertion is performed by inserting the lower end of the feed pipe 3 into which the crushed raw material is charged. The problem here is that the lower end of the feed tube 3 is usually located in the insertion hole 22 and the peripheral portion of the insertion hole 22 is covered.
If the lower end of the insertion hole is worn by the rebound of the raw material, the peripheral edge of the insertion hole 22 is exposed. Therefore, the periphery of the insertion hole 22 is worn due to the rebound of the raw material, and the life of the rotor 2 is shortened, which is uneconomical.

を取り付けたことである。An embodiment of the present invention will be described below with reference to the drawings. <A> Overall Structure of Rotor As shown in FIG. 1, the rotor 2 of the present invention is an improvement on a conventional rotor. That is, the rotor 2 is composed of upper and lower discs 23 and 24 which face each other, and a wall board 25 which connects the discs and defines a passage leading to the discharge port 21 opened at the peripheral edge. In the center of the upper disk 23, an insertion hole 22 for inserting the lower end of the feed pipe 3 for inputting the crushed raw material is opened. A feature of the present invention is that a ring-shaped protective member 4 having abrasion resistance is formed along the periphery of the insertion hole 22.

られる。<B> Protective Member The protective member 4 is a ring-shaped member made of a wear-resistant material such as special high chrome. The cross-sectional shape of the protection member 4 includes, for example, a thick portion 41 for protecting the peripheral portion of the insertion hole 22, and a hook portion 42 that protrudes outward from the upper portion of the thick portion 41 in the horizontal direction. Consisting of As shown in FIG. 1, the hook portion 42 is provided on the upper surface of the upper disk 23 to detachably hook the protection member 4 to the periphery of the insertion hole 22. The shape of the protection member 4 is not limited to the above-mentioned shape, but may be any shape as long as the peripheral portion of the feed tube insertion hole 22 of the rotor 2 can be protected from abrasion due to collision of the raw material. Therefore, the ring shape is divided, and the lower surface of the rotor upper disk 23 is formed to have a U-shaped cross section that can simultaneously protect the lower surface. In addition to the above-mentioned latching type, it has wear resistance such as special high chrome. It is also conceivable to fasten with a bolt made of a material.

That is, the structure of the conventional rotor is uneconomical because the raw material collides with the peripheral edge of the feed hole insertion portion and may be worn, so that the life of the rotor is shortened. On the other hand, the rotor of the present invention has a structure in which a protective member having wear resistance is attached to the peripheral edge of the insertion hole. Therefore, wear of the periphery of the insertion hole can be prevented, and the life of the rotor can be extended, which is economical.
