1. Introduction. Clinker milling is the last step in production of Portland cement. Nodular clinkers produced in a rotary kiln in a cement plant are ground together with gypsum into a fine powder of particle size less than 100 μm and with a surface area of 330380 m 2 /kg for production of ordinary Portland cement (Bye, 1999).The fineness of the particles is a critical aspect that governs ...

The mill was crashedstopped during various periods. Samples were representatively taken from inside the mill in distances of 2030. cm along the center and edge lengths for selected periods which are 2, 5, 10, 15, 20, 30, 45 and 60 min.. For modelling of grinding process in pilot scale ball mill, determination of the particle size distribution of feed and product of mill is an essential step.

For example, the comminution process of cement clinker followed the firstorder grinding kinetics with the balls and rod media. Meanwhile, the grinding rate of the rod mill was higher than the ball mill [22]. The equivalent granule size declined while its specific surface area increased gradually with grinding time [23].

During the last decade numerous protocols have been published using the method of ball milling for synthesis all over the field of organic chemistry. However, compared to other methods leaving their marks on the road to sustainable synthesis ( microwave, ultrasound, ionic liquids) chemistry in ball mills is rather underrepresented in the knowledge of organic chemists.
