The crushing parameters of one single particle do not depend only on the features of the particle but also on the design and operation parameters of the test apparatus. Therefore, these parameters are not properties of a particle, they are per se system parameters too. There is no intrinsic property of a particle or a material related to crushing!

The efficiency of mechanical crushing is a key metric for evaluating machinery performance. However, traditional contact-based methods for measuring this efficiency are unable to provide real-time data monitoring and can potentially disrupt the production process. In this paper, we introduce a non-contact measurement technique for mechanical crushing efficiency …
