coal level measurment in tube ball mill

  • A new model-based approach for power plant Tube-ball mill

       Tube-ball mill is another dominant type of coal mill apart from Vertical Spindle mill in industry. Compared with the Vertical Spindle mills Tube-ball mills have a much higher grinding capacity. However there are fewer literatures found in studying Tube-ball mill operation compared with the Vertical Spindle mill.
