Abstract
Crushing equipment is involved in cement, electric power, nonmetal and other industries. However, the multi-particle crushing behaviors and characteristics are essential to the crushing equipment performance. In this paper a numerical model for multi-particle crushing has been established in order to investigate the behaviors and characteristics of particle crushing. The evolution process of particle crushing, size effect, law of energy accumulation and dissipation were comprehensively discussed. The particle crushing behaviors are remarkable. when multiple particles were crushed, a large number of failure units and acoustic emission (AE) appeared at the top. The energy consumed by multi-particle crushing was low, and multi-particle crushing was more efficient. The particle size is of great importance to the crushing characteristics. The bigger a particle is, the easier the crushing happens. This study could give useful suggestions in the design of the crushing technology.
