The crusher rotor is the core of the hammer crusher, and its structural form can be divided into alignment type and cross arrangement type. Among them, the alignment type refers to the arrangement of the crusher hammers in a mutually aligned manner. According to the size of the crusher rotor, the circumference is divided into 4 to 6 rows, and each row of 7 to 11 crusher hammers are different. Cross-arrangement means that the crusher hammers are arranged in a mutually intersecting manner. According to the size of the crusher rotor, the circumference is divided into 4 to 6 rows, and each row of 6 to 8 crushers are different.


In view of the short life of the crusher rotor in the hammer crusher, easy damage, low crusher output, coarse grain size and other weaknesses, CFTC introduced a modified enhanced crusher rotor:
1. Using international advanced finite element analysis technology to effectively improve the crusher rotor design;
2. According to the stress analysis of the crusher rotor stress, the weak design is adopted, and the reinforcement design is adopted and high-strength high-quality alloy steel is adopted;
3. The tungsten-titanium alloy full armor protection design on the rotor surface of the crusher. The hammer crusher rotor body of this structure greatly reduces the stress concentration of the hammer disk and the end hammer plate, enhances its strength and effectively prevents the breakage. The problem, and can effectively prevent the crusher from getting stuck, can improve the life of the crusher rotor more than double;
4. Using variable moment of inertia design, effectively improve the crushing efficiency, increase the crusher output, and reduce the fineness by 20~30%;
5. The rotor end plate of the crusher and the shaft hole on both sides of the hammer plate are thickened and extend around the connecting bolt hole. The thickened part is provided with a crescent groove for facilitating the hammering of the crusher. The hammer plate and the end plate are directly connected to the string. Mounted on the spindle.
