The crusher is a common large-scale equipment in industry and is widely used in multiple sectors, such as mining, construction, metallurgy, and so on. This equipment is used to crush and grind hard raw materials, turning them into finer particles to facilitate subsequent production processes. However, the rotational speed of the crusher is a very important factor affecting the output of the equipment. The following text will explore its detailed impact with examples.
First, the working principle of the crusher
The working principle of a crusher is to crush or grind materials through high-speed rotating hammer heads or tooth plates and other crushing elements. During the crushing process, the materials are subjected to the action of impact force and friction force, gradually being crushed into small pieces or powder. The higher the rotational speed of the crusher, the greater the linear velocity of the crushing elements, the greater the impact force and friction force on the materials, and the better the crushing effect and output.
Second, the influence mechanism of the crusher’s rotational speed on the equipment’s output
1. Material force conditions: The higher the rotational speed of the crusher, the greater the impact force and shearing force that the material is subjected to in the crushing chamber, and the better the crushing effect, which may increase the output of the equipment. However, excessively high rotational speed may lead to excessive crushing of materials, increase the content of fine powder, and instead reduce the overall output.
2. Crushing efficiency: Appropriate rotational speed of the crusher can enhance the material passing rate and crushing efficiency, thereby increasing the output of the equipment. However, if the rotational speed is too high, it may cause the material to stay in the crushing chamber for too short a time, and be discharged before being fully crushed, reducing the crushing efficiency and output.
3. Equipment wear: The increase in the rotational speed of the crusher will accelerate the wear of the equipment, especially the impact on vulnerable parts (such as crushing teeth, screens, etc.) is more obvious. Excessive wear and tear not only reduces the working efficiency of the equipment, but may also cause equipment failure, affecting output and production stability.
