  • Modelling and Simulation of Dynamic Behaviour in Crushing

    Crushing plants are a vital part in the production of aggregates and metals. Plants are traditionally simulated with a steady-state simulation. With steady-state simulation the plant is simulated until equilibrium is achieved. However crushing is a continuous process and as such it is subjected to variations and changes in performance depending on the dynamics of the system. A different

  • Analysis of the Cavity Formation Mechanism of Wedge Cut

    The basic process of cut blasting is to break rock throw fragments and form a cavity. Based on the characteristics of cut blasting and the combined effect of stress waves and detonation gas the evolution process of wedge cut blasting is divided into two stages and a theoretical model is proposed to investigate the cavity formation mechanism by theoretical analysis and field tests.
