How Cement Is Made - Portland Cement Association
Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.

An Introduction to Electric Power Transmission Presentation
5 Current – The flow of electricity or the movement of electrons through a conductor typically measured in watts. Direct Current (DC) – Electric current flows continuously in the same direction as contrasted with alternating current. Distribution Line – A line that carries electricity at lower voltages of 12kV to 44kV and is used to distribute power
Iron Ore Sinter - an overview | ScienceDirect Topics
The annual production of cement [6] and COC [7] in the main countries, as well as the iron ore sinters, blast furnace (BF) slags and steel slags [8,9] in China are extremely large. Additionally, the calcination plants (perlite and lime, etc.) and boilers in power plants would also produce huge amount of hot granular materials.

Power plant - Energy Education
The type of primary fuel or primary energy flow that provides a power plant its primary energy varies. The most common fuels are coal, natural gas, and uranium (nuclear power).A substantially used primary energy flow for electricity generation is hydroelectricity (water). Other flows that are used to generate electricity include wind, solar, geothermal and tidal.

Slag Viscosity - an overview | ScienceDirect Topics
Ken Mills, in Treatise on Process Metallurgy: Industrial Processes, 2014. 1.9.6.2 Viscosity (η). The slag viscosity is important because (i) it affects the lubrication supplied to the mold (1/ η), (ii) the SEN erosion rate is proportional to (1/η), and (iii) high-viscosity fluxes are used to minimize slag entrapment although at the expense of the powder consumption [3].
