  • The effects of mill speed and filling on the behaviour of the load in a

    Feb 2, 1988 The mill was operated in a batch mode, and was loaded with a charge of balls to give the desired filling of 30,. 40, or 50 per cent (bulk load volume/mill volume). The requisite amounts of sand and water were then added to form the pulp. The mill was rotated at 75 per cent of critical speed for approximately

  • Volume Load The Cement Grinding Office

    The measurement of the ball charge volume load (or filling degree) is essential to maintain the absorbed power of the mill and consequently the mill production. The most common way to evaluate the filling degree is the measurement of the free height inside the mill (vertical distance between the top of the charge and the
