Apr 29, 2017 . After a ball-mill has been in continuous and steady operation for, say, a year, during which time balls of only one diameter have been added at regular intervals, it may be assumed that the ball charge has reached a constant working condition. In this constant state, there is no change in the charge from day.
Apr 4, 2017 . If this is a concern, and if the client has already bought the mill, your options may be limited. One option could be to install a grate possibly with high capacity pulp lifters, to minimize the slurry pool at 20% ball charge. The grate could later be removed to allow for operation at higher ball charges. Obviously.

There are literally thousands of ball mills in use throughout the world, many of them in the cement industry. Few installations have a comprehensible method of controlling and recording exactly what ball . or filling level of the ball charge can easily reduce the efficiency of grinding (possible production rate) by 5% to 20%.
Ball charges: This calculator gives the surface and the average weight of the ball charges. It gives also a rough interpretation of the ball charge efficiency: - Ball top size (bond formula): calculation of the top size grinding media (balls or cylpebs):. - Modification of the Ball Charge: This calculator analyses the granulometry of.
Raw mill: The raw mill will be operate with a much coarser ball charge than the cement mill mainly because of the bigger slot sizes of the partition wall. The transition zone consists of 50 mm and 60 mm balls. The basis is a 50 mm ball size for 5% residue on the 4 mm.

charge. The shell lining in the second compartment or in a one-compartment cement mill is a corrugated lining designed to obtain maximum power absorption and grinding efficiency. For special applications a classifying shell lining may be supplied for fine grinding in the mill. The ball charge mill consists of grinding.
Calculations of media charge. To calculate media charge for batch mill. M = 0.000929 x D2 x L where : M = Grinding media charge in kgs. D = Internal Dia of the Mill in cms. after lining. L = Internal length of the mill in cms. after lining. To calculate grinding media charge for continuous type ball mill, M = 0.000676 x D2 x L
