The working principle of the hammer crusher is to use a high-speed rotating rotor to drive the hammer of the crusher to impact the material, causing cracks on the surface, and then breaking along the fragile parts such as the bedding surface of the material. The crusher rotor is composed of a main shaft, a hammer plate and a hammer shaft. It is a key component of the crusher. Then how to choose the crusher rotor in the production process, Zhengzhou prosperous engineering experts have been studying for 17 years, and have experience in machine deployment:
The diameter of the crusher rotor is generally determined by the size of the crushed material. Normally, the ratio of the diameter of the rotor to the size of the crushed material is between 1.2 and 5. The value of the large crusher is small. The length of the rotor is related to the production capacity of the crusher. Generally, the ratio of the diameter of the rotor to the length is between 0.7 and 2. When the impact resistance of the material is large, the ratio should be larger. The rotation speed of the rotor affects the crushing efficiency and production capacity of the crusher, which is an important working parameter of the crusher. At present, the peripheral speed of the hammer crusher is 18-70m/s, the speed of the small and medium-sized crusher is 750-1500r/min, the peripheral speed is 25-70m/s, and the speed of the large crusher is 200-350r/min. The circumferential speed of the rotor is 18-25m/s.
