2011-2-1  More specifically, in the case of an overflow mill, at constant ball filling, the mill performance increases as the pulp volume becomes more compact (mainly at the shoulder) and as the ball load expands (mainly at the toe). At constant ball filling degree, this mill’s performance increases as the pool angle and dry ball angle go toward zero.

2019-12-5  Pulp Lifters Manufactured with a rubber-lined fabricated steel base, our pulp lifters use high-quality designs that ensure the correct volumetric flow of the pulp. Rubber wear plates designed to be bolted onto the high-wear areas of the ball mill liner improve the performance life of your mill.

2016-9-10  The secondary mill at Waterval UG2 Concentrator was already fitted with an online ball and pulp load sensor, the Sensomag. The information obtained from the sensor is in the form of shoulder and toe positions for the ball and pulp filling in the rotating ball mill. The mill was surveyed at various

Addition of pebbles to a ball-mill to improve grinding

The volume of pulp in some experiments was increased to mimic pulp filling in an overflow discharge ball-mill. All the experiments in this phase were conducted using a silicate ore. The rate of production of material finer than 75 µm, when using a 25/75 mixture, was virtually identical to that of the corresponding ball-milling experiment.

2009-8-26  The pulp weight in the mill is obtained by subtracting the mill weight during the test from the empty mill weight, including the ball charge, at the start of the test. The pulp volume of the pulp in the mill is then calculated using the mill discharge density (before dilution) obtained during the sampling.

In Fig. 6.4 are plotted curves, again according to Coghill and Devaney, which show the effect of pulp density upon selective grinding and it is at once evident that a more rapid reduction of the larger fractions is obtained with a pulp of moderate thickness than with a very thick one. The probable explanation of this phenomenon is that with a fluid
