The choice of apparatus for obtaining finely dispersed powders with maximum grinding efficiency is the most important problem. As a rule, for this purpose, installations are used, which are a complex of grinding units. When designing grinding units, in addition to dispersion, size of pieces and mechanical properties of the initial material, it is necessary to take into account the requirements for the final product. A prerequisite for the implementation of developments in the industry are: the minimum possible cost of electricity and the duration of the technological process, the simplicity of design and operational reliability of the units.
The cement industry is currently making various efforts to reduce CO 2 emissions. The blended cement produced by lowering the amount of clinker with using mineral additives has expanded as the trials to reduce CO 2 emission as well as to utilize its advantageous properties. And standards related to blended cement have been already set in all regions of the world. It is evaluated and reviewed the standards of blended cement according to the types and usage ratios of mineral additives that can be blended, which are covered by the European Standard (EN 197 1:2011), the Euro-Asian Standard (ГОСТ 31108-2020) and the U.S. Standard (ASTM C 595-16), respectively. In accordance with the blended cement standard established in each region, it is necessary to promote and expand the use of blended cement to reduce the CO 2 emission currently facing as well as to utilize various advantages of using blended cement.
