The primary impact crusher, in particular, uses force to crush materials, generating enough energy to break the material down into smaller particles. Additionally, primary crushers have a higher capacity and can handle larger tonnages compared to secondary crushers, which typically have lower maximum capacity limits.
2.1 Key Structural Components. An impact crusher is composed of several key components that work together to achieve efficient crushing: Frame: The frame is the main structure of the crusher, providing support and stability. It houses all the other components and must be robust and durable to withstand the forces generated during crushing.
This paper presents an optimal control model to improve the operation energy efficiency of a vertical shaft impact (VSI) crushing process. The optimal control model takes the energy cost as the performance index to be minimized by accounting for the time-of-use tariff and process constraints such as storage capacity of the VSI …
