2019-5-20 The Tube Mill, used for finish grinding of cement, but also for rawmix and coal, was first patented in 1891 (Meyer Joseph Davidsen, a Dane living in Paris) and subsequently manufactured in 1893 by FLS. The mill had many features that have continued into modern designs. The tube was of welded mild steel plate, of length 3-5 times the diameter.

2021-4-16 Cement Grinding and Distribution The clinker is stored and then finely ground. Gypsum is added to control setting time, along with supplementary cementing materials, such as fly ash or slag, to obtain a fine powder called cement, with the desired properties of strength and chemical resistance.

The grinding process of cement absorbs 60-70% of the total energy employed. Finish grinding accounts for about 38% of specific electric power consumption. The quantity of energy required by the process to obtain the correct fineness is only partially employed for the creation of new surface: in fact most of the total energy is lost as heat.
Read More1992-11-24 To reduce the need for water addition to cement products containing cement manufactured in roller mill plants, a method is described for finish-grinding of the cement, whereby a certain prehydration of the cement is ensured in order to compensate for the reduced retardation efficiency deriving from a gypsum component of cement manufactured by roller mill plants.
