Ball mills are commonly used in the manufacture of Portland cement and finer grinding stages of mineral processing, one example being the Sepro tyre drive Grinding Mill. Industrial ball mills can be as large as m (28 ft) in diameter with a 22 MW motor, [4] drawing approximately % of the total world's power (see List of countries by electricity consumption ).
Grinding systems are either 'open circuit' or 'closed circuit'. In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer product and returned for further grinding. Cement Mill Has A Wide Range Of Application
Closed circuit ball mill with two compartments for coarse and fine grinding and a drying compartment with lifters are generally found in cement plants for raw material grinding. Compartments (filled with grinding media) are divided by a double diaphragm with flow control to utilize maximum mill length for effective grinding.
Raw Material Grinding. Ground material then passes through a classifier. A total of 90 percent of the resulting raw meal is collected at the cyclone and rest at the main bag house. It is then transported to the blending cum storage silo. The hot gas required during grinding is drawn from the preheater waste gas.

Cement grinding operation may be performed in one of the following mill setups. Ball and tube mills. Vertical Roller Mills (VRM). Roller press with Ball mill. Ball Mill. Ball mills with high efficiency separators have been used for cement grinding in cement plants all these years. Ball mill is a cylinder rotating at about 7080% of critical speed on two trunnions in white metal bearings or slide shoe bearings for .
The major equipment in the plant were a two chambers central discharge ball mill for raw material grinding, a dry process kiln with twin string preheater (PH) and a precalciner (PC) in calciner string, grate cooler and a two chamber, closed circuit ball mill for cement grinding.
For productivity and quality reasons, grinding is mostly performed in closed circuits: The ball cement mill (CM) is fed with raw materials. The milled product is fed via a recycle elevator to a dynamic separator.
for cement grinding circuit. The cement grinding mill model that relates model of interest is multivariable in nature. The elevator current is directly correlated with the amount of material inside the cement grinding mill or the material circulated. As shown earlier, the amount of material circulated in the cement grinding circuit is an indirect measure of the
Nov 01, 2001· Modelling cement grinding circuits The results reported earlier have shown that tube mills can be modelled as several mills in series, and the internal partition in tube mills can be modelled as a screen which must retain coarse particles in the first compartment but not impede the flow of drying air.
