The crushing and grinding theory evolves with the progress of industrial level. The crushing and grinding process is closely related to production in each and every industrial sector, such as metallurgy, non-metallic mining, building materials, coal, environment protection field, chemistry, food, cosmetics, papermaking, microelectronics, optics, biology, medicine, and ceramics and so on. Due to the rapid development of modern S&T and economy, solid theoretical foundation is laid and superior research environment is provided. In recent years, researchers have conducted study on crushing and grinding equipment from different perspectives. Fruitful achievements have been attained by various researches on the impacting, squeezing, grinding, and exploding role in crushing equipment.

According to material feeding-in pattern, crushing equipment can be divided into single-particle crushing machine and laminating crushing machine. The laminating crushing can be further divided into material layer crushing, particle group crushing and intergranular crushing. Single-particle crushing is the basis of crusher working principle. Scholars from home and abroad have carried out extensive research work on it. Laminating crushing happens among bulk materials by collision, impacting and grinding effect. Due to the interaction of material, the layers are formed. We can refer to the theoretical achievements to make a breakthrough in national crushing equipment. The research on and improvement of crushing equipment, such as impact crusher, jaw crusher, tertiary impact crusher, become more and more comprehensive with the advancement of national economy.
