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 330–380 m 2 /kg for production of ordinary Portland cement (Bye, 1999). The fineness …

Clinker grinding technology is the most energy-intensive process in cement manufacturing. Traditionally, it was treated as "low on technology" and "high on energy" as grinding circuits use more than 60 per cent of total energy consumed and account for most of the manufacturing cost. Since the increasing energy cost started burning the benefits …

A higher gypsum dehydration in the vSMM would theoretically be expected if the amount of sulfate agent in the cement were at the normal level of 5 mass%. Bearing in mind the test conditions that have been described, the following options are suggested for raising the degree of gypsum dehydration in the clinker-gypsum mix (C85/G15) in a vSMM:

The raw materials are then ground in suitable ball mills/vertical roller mills (VRMs), both of which are common grinding mills, in order to achieve the targeted fine powder, which is stored in pre-homogenisation silos (Aïtcin and Flatt Citation 2015; Hewlett Citation 2003). In stage three, the raw mix is fed into a preheating chamber.
