A review made by CEMBUREAU of the world and European cement production and consumption and the world energy market.
The article presents data on the existing, under construction and planned cement plants of the Republic of Tajikistan, on cement production and import. Since 2013 there has been a significant growth in the cement production in the country.
The article reports on the ceremony devoted to commissioning of new greenfield cement plant in Ferzikovo, Kaluga oblast (capacity: 1.86 Mta) owned by Lafarge Group. It describes the process flowsheet and basic equipment characteristics. Investments in the projec...
The quantity of clinker and cement produced in January-June 2014 is presented as well as the consumption of cement by the regions of Ukraine is given in tables.
Currently, at many cement factories there are problems with material spillage from the conveyor belts and, respectively, with immense dust emissions into the air. To prevent this, and to ensure safe conditions for the operators during maintenance of conveyor belts, Fren...
Often, local geography such as mountainous terrain, overflowing rivers or heavily populated areas interferes with smooth material flow from the quarry to the place of its processing by the shortest route. Long detours may significantly affect the speed and cost of deliv...
Extremely coarse-ground raw cement meal can increase the amount of the melt and reduce the melting temperature to 1100°C. The higher reactivity of the extremely coarse-ground raw meal can increase its saturation factor and the silicate module. The thermal treatment of t...
The measurement and control of particle size distribution in cement are very important for both the desired product composition and controlling production costs. Conventional methods, such as measuring the particle size distribution by sieving and determining fineness a...
The article describes the theoretical concepts underlying the technology of material grinding. The main factors affecting energy consumption in grinding cement are considered. The laws of solids grinding and equations to estimate the parameters of particle size distribu...
The article describes the effect of Portland cement grinding in ball and vertical roller mills on the properties of the finished product. It is shown that to improve the quality of Portland cement an improvement of its particle size distribution is required, which is es...
