In this context, modeling of full-scale continuous ball mills could provide significant insights and help process design (King, 2001). Ball milling, where balls hit and grind particles in a rotating horizontal tube, is reported to be an inefficient unit operation (von Seebach et al., 1996, Fuerstenau and Abouzeid, 2002).
For a continuous grinding mill, however, a classification mechanism and a discharge function must be added into the size reduction model to allow discharge of the ground product based on the particle size. Data acquisition. Five sets of full scale ball mill operational data were used to validate the specific energy-based ball mill model.
Ball mills are among the most variable and effective tools when it comes to size reduction of hard, brittle or fibrous materials. The variety of grinding modes, usable volumes and …
There are three types of grinding media that can be used in ball mills of cement plants. 1. Steel Balls. Steel balls are one of the most widely used grinding media in cement ball mills, their diameters can range from 20mm to 120mm according to different grinding requirements. In a cement ball mill, generally, φ50–100mm steel balls are …
As a second step in the ball mill model development, the specific energy-based size reduction model was extended from batch grinding to full scale ball milling in continuous operation mode, which is reported in this paper. 2. Modelling discharge function. In essence the size reduction model can be applied as a basic structure for both …

The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition.
