The article reviews an exhaust gas heat recovery system at a cement plant. The heat is used to generate electricity. The average electricity production is 45 kWh per tonne of clinker. The system operation is consistent and the payback period of investments in it is shor...
The article analyzes various mechanical methods of clinker conveyance present on the market today. It explains the layout, describes various tools for optimum selection of a conveyor for main sections of production facilities and formulates the key selection criteria. I...
The article describes reconstruction of a slag drier involving the installation of new gas purification equipment. This is a bag filter with pulsed regeneration of filter sleeves with compressed air and a semi-open cycle system that prevent partial return of purified ga...
The RHI Company cement and lime department has developed a number of services for technical support of cement and lime production. The services include in-depth examination of the production process by detailed analysis of the data obtained from the customer, and additi...
The work involved studies of the effect of various cement grinding schemes on the product particle shape and cement properties, dependence of the particle shape on their dimensions, and also the effect of the product particle morphology on cement properties. Ordinary ce...
The study examines the effect of silica-containing additives – microsilica, white soots and colloidal silica – on calcium concentration, pH value and Ca(OH)2 supersaturation degree of the liquid phase of Portland cement pastes at the early hydration period. It i...
Electron-microscopic studies of binding cement compositions for dry construction mixes confirmed the possibility of using them within finely dispersed slags as fillers. In the process of combined hydration of cement and finely dispersed steel slags, one observes uniform...
The article cites the results that enabled envisioning the process of cement clinker production as a single structure formation process accompanied by sequential ordering, compression and strengthening of its structure. It was possible to establish and experimentally co...
Spills of dust and other materials often occur in cement production facilities. Sibilia Company (Italy) substantiates the need for keeping cement production clean and offers recommendations on the most effective methods of achieving this goal.
The article provides characteristics of fabric filters designed for exhaust gas dedusting. While assessing their application efficacy, one should take into account the cost of the filters, power consumption and their regeneration technology.
