Assuring the quality of the massive quantities of cement produced worldwide each year is a daunting task. Currently, the cement industry performs extensive physical testing to assess the quality of their product, resulting in large costs for both materials (and their disposal) and labor. One of the major goals of the Virtual Cement and Concrete Testing Laboratory (VCCTL) consortium is to provid...

The flow field, pressure drop, and separation efficiency of an industrial cyclone separator were computationally investigated using the Reynolds stress model simulations. effects flapper valve on static cut size, slope grade curve revealed. For that, was simulated in three operation regimes, when is open, closed, without valve. results showed that a increases size by 3.4 % it position “closed” ...

The separation of bubbles in a gas–liquid cyclone is complicated. A combination numerical simulation and visual experimentation was considered apt to reveal the microscopic mechanisms bubble flow. First all, cyclones with different structures were numerically simulated. calculation results show that larger diameter exhaust port, better flow effect. When port 24 mm, gas discharge efficiency 8% h...

This paper analyzes an existing maintenance management system in a cement factory in the Kingdom of Saudi Arabia using a modified questionnaire. The analysis shows that there are strong areas such as predictive maintenance and maintenance automation. Other areas are found weak such as training programs and maintenance reporting. Some areas are found mix between strong and weak such as maintenan...

Several different carbon-capture technologies have been proposed for use in the cement industry. This paper reviews their attributes, the progress that has been made toward their commercialization, and the major challenges facing their retrofitting to existing cement plants. A technology readiness level (TRL) scale for carbon capture in the cement industry is developed. For application at cemen...
