Description

There are three famous crushing theories in the international comminution field, namely, area theory, volume theory and crack theory. Due to the limitation of historical conditions and scientific research means, these traditional crushing theories are all based on dynamics and equilibrium state. On the basis of continuous gradual change process and steady process, the theoretical study of comminution physics and comminution power consumption is carried out. But in fact, the distribution of defects in materials is random, and the comminution process is discontinuous, abrupt, irreversible and nonlinear. Discrete open system, with the development of science and technology, the research of comminution theory has been expanded to multi-field and interdisciplinary direction, mathematics, physics, mechanics of materials research.Fruit is applied to the research of crushing theory.

 

  1. comminution machinery. The influence of mechanism design, working principle, mechanical structure and structural parameters on the crushing effect is studied. A new crusher is developed on the basis of theoretical research.

 

  1. comminution physics. On the basis of studying the crushing law of crushed materials under external force, the research scope is carried out to study single particle crushing, material layer crushing, selective crushing and crushing limit, etc.

 

  1. comminution power science. Study the relationship between the input work of comminution process and the change of material potential before and after crushing. Three famous comminution theory area theory, Volume theory and crack theory reveal the relationship between energy consumption and crushing effect from different aspects. The state equation of power consumption in the process of fragmentation is given quantitatively.

 

  1. the dynamics of crushing. The relationship between particle size reduction and time is studied, and the dynamic relationship between input and output of crushing process is revealed. The instability and stability of crushing process are illustrated by nonlinear dynamics study.

 

  1. Fractal technology. Fractal technology better reflects the nature of fragmentation, ore and natural sand basically accord with the fractal law. The fractal theory is used to study the fractal dimension Ds and power consumption on the surface of broken ore particles. Furthermore, the rule of breaking power consumption is revealed.

 

  1. catastrophe theory. According to the characteristics of discontinuity, catastrophe, irreversibility, nonlinearity and open system, the material comminution process is studied by using catastrophe theory and dissipative structure. The physical nature of the destruction of the old structure and the formation of the new structure in the process of material crushing is illustrated by the nonlinear irreversible process thermodynamics of material crushing. The mechanism of material breaking is promoted to the category of nonlinear thermodynamics and nonlinear dynamics.

 

7) discrete mathematics. The discrete element method can be used to study and simulate the wear state and law of different shape wear parts of crusher under different working conditions. The data obtained from the analysis can be used to optimize the structure and technological parameters of the crusher.
