However, in the cement industry, the grinding process is more of an "art" than engineering and the equipment manufacturers exclusively hold the "know how". The process is designed and operated using carefully guarded "recipes" and rules. In such as environment there is little or no room for process understanding and improvement.
2003-1-1 Comminution is a crucial part of cement manufacture, which includes crushing and grinding of raw materials and clinker grinding. Comminution, however, is extremely energy intensive and consumes...
2010-4-1 Grinding trends in the cement industry Summary: The main trends concerning grinding processes in the cement industry are still higher efficiency, reduction of the power consumption and system simplicity. In the case of new orders, vertical mills have increased their share to over 60 % and ball mills have fallen to less than 30 %.

The cement industry processes requiring fine grinding are rawmix preparation, fuel preparation and grinding of clinker to make cement. All three may require a preliminary crushing stage. In the case of raw materials, attempts have always been made to minimise the amount of crushing needed by extracting the rock in the finest possible state.

2017-3-26 However the fineness of cement grinding to a certain degree, there will be "reunion" phenomenon”. this is because the cement produce electric charge in the process of grinding, the positive and negative charges on cement particle’s surface attract each other, and cement grinding aid is a good way to avoid the occurrence of this phenomenon.
The cement manufacturing process involves three components: the mining and preparation of inputs; the chemical reactions that produce clinker; and the grinding of clinker with other additives to produce cement. The feed for older kilns is a slurry of inputs, the wet kiln process, while large new plants mix dry materials for introduction to the kiln.
2019-1-6 - Grinding process: Clinker is grinded and is blended with a small amount of gypsum to make finished cement. Other kinds of cement include Slag cement or pozzolan cement with Ground-Granulated Blast Furnace Slag and Pozzolan volcanic rocks respectively. Don’t be confused between Cement and Concrete it`s not the same.

Cement mills are the biggest consumers of electrical energy. Good grinding organization and intense monitoring can keep grinding cost under control. Regarding cement grinding, the focus is on the following topics: • Different mill types • Concepts for grinding plants • Co-grinding / Mixing • Grinding process and cement
2021-4-15 Therefore, limiting grinding power demand is a major industry focus. The end-product evolution is another key issue to address, with respect to the expansion of the cement additives range and cement/clinker ratio, as well as the emergence of ultra-fine products in the cement industry.

The cement industry is the most important consumer of rubber waste. It uses 236,000 t of scrap tires (26 MJ/kg calorific heat) and 290,000 t of industrial waste (plastic waste, paper, textiles, etc., 22 MJ/kg caloric heat) (VDZ, 1999).Table VI.5.21 shows a comparison of components of traditional fuels and scrap tires.
