izontal ball mills. Gypsum is typically the basic source of sulphates (SO 3) in the cement. The effect of gypsum on the cement quality is critical and two-fold. It affects two of the main properties of this product, setting time and strength.1 For this reason gypsum is added during cement grinding in the mill

Lynch et al. and Benzer et al. developed a modeling approach for the two compartment cement mills using extensive data around and inside the mill,, . This paper is concerned with the model of a fully air swept ball mill operating in a raw material grinding circuit.
A data-driven modeling method is proposed. According to the actual production data, the model of ball mill load and cement granularity is established by using recurrent neural network. The validity of the data driven model is verified by simulation analysis to identify the load of ball mill and the size of cement.
the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential features of a model for mill power.

Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.
A deeper understanding of the milling operation of ball mills helps mineral processing engineers to control and optimize them, and therefore, reduce their consuming power. In this work, the milling operation of ball mills is investigated using two methods, i.e. DEM and combined DEM-SPH. First, a pilot scale ball mill with no lifter is simulated by both methods.
Ball mills are used for grinding of rocks, cement clinker and limestone from 10 to 100 mm feed sizes down to sub-millimetre product. They are typically rotating cylinders with diameters from 3 to 6 m and lengths from 6 to 12 m. The flow of particulate solids within these mills can be modelled using the discrete element method (DEM).

Grinding in ball mills is the most energy-intensive comminution operation; for instance, about 110 kWh of electrical energy are consumed per ton of cement produced. Around 70 % of this energy is needed to grind the raw material and the clinker, while only 1–5 % of the supplied energy is needed for the explicit particle breakage [ 3, 20 ], i ...

CEMENT GRINDING SIMULATION To optimise cement grinding, standard Bond grinding calculations can be used as well as modelling and simulation techniques based on population balance model (PBM). Mill power draw prediction can be carried out using Morrell's power model for tumbling mills (Morrell, 1998).
