Coal Grinding Cement Plant Optimization

Drying and grinding are generally being done in either air swept ball mill or a vertical mill. The selection of mill system will depend mostly on the factors like initial capital cost, drying and grinding capacity required, cost of energy (power) etc. Coal Fineness: It is understood generally that the finer we grind, the easy it is for burning

Energy-Efficient Technologies in Cement Grinding

They are used in grinding of cement raw materials (raw meal) (i.e. limestone, clay, iron ore), cement clinker and cement additive materials (i.e. limestone, slag, pozzolan) and coal. Multi-compartment ball mills are relatively inefficient at size reduction and have high specific energy consumption (kWh/t). Typical specific energy consumption is 30 kWh/t in grinding of cement. Barmac-type

Coal grinding with water jets ScienceDirect

01/01/1993· Minimum specific energy attained in the tests is around 0.3 MJ/kg, roughly corresponding to 87 kWh/t, quite higher than that normally required by traditional grinding mills. Actually, as shown by Table 2, a ball mill would give a similar size reduction with an energy consumption of about 15 kWh/t (6 times lower). Table 2 Reported avarage energy requirements for several comminution devices (3
