Simulation of the Energy

The motion dynamics of the milling bodies in the working chamber of a planetary ball mill is simulated. Numerical data on the influence of the processing conditions in a planetary ball mill (carrier rotation frequency) on the motion trajectory and the energy-force parameters of the contact interaction of the milling bodies between each other and the working chamber wall are obtained.

Application of Fractional Fourier Transform for Prediction

Jun 26, 2019In cement plant and power plant, ball mills remain in current and widespread use. The load parameter inside a ball mill directly impacts the stability of the production process, the grinding production rate, and the quality of the product in the grinding process. Accurately predicting the load from acoustic signals remains a challenging problem because of the nonlinearity and high dimensions
