basic information
In this lecture, we will explain the principles of grinding, covering the mechanisms from coarse grinding to fine grinding, the laws of energy, the characteristics of dry and wet grinding, and the basic matters related to the optimal operation of grinding machines, while discussing the concepts of effective grinding. Additionally, grinding activates the produced powder, and we will outline this phenomenon, emphasizing its important role in effectively advancing post-grinding processing processes (such as dissolution and heat treatment). We will enumerate representative examples and recognize the role of grinding. Furthermore, we will explain the utility of DEM simulation for improving energy efficiency in grinding and for constructing universally optimal grinding structures and scale-up methods. This is expected to enhance our understanding of grinding and its engineering applications more than ever before. In the latter half, we will discuss recent topics related to classification, evaluation methods for practical operations, and points to consider. In particular, we will explain the high-performance technology of cyclones utilizing rotational flow, including experiments, simulations, and videos of visualization experiments. Additionally, we will provide insights into recent trends of standard particles both domestically and internationally.
