    The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. Then, discharge of ground material performed.Approximately cylindrical flame. Heat transfer from this flame and the hot combustion gases that flow up the kiln dries, heats, and calcines the counter flowing lime solids. Rotary lime kilns in the pulp and paper industry range in size from 7 ft (2.1 m) in diameter by 175 ft (53 m) long to 13.5 ft (4 m) in diameter by 400 ft (122 m) long.

    The materials from the cement mill and the cyclone dust collector are classi fi ed according to their size. The coarse material (63.23 t h), accounting for 26.97 of the input.Cement, but is also influenced by water cement ratio, fineness and curing temperature. As each one of these factors is increased, heat of hydration increases. For usual range of Portland cements, about one half of the total heat is liberated between 1 and 3 days, about three quarters in 7 days, and nearly 90 percent in 6 months.

    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.Hydration products. The products of the reaction between cement and water are termed hydration products. In concrete (or mortar or other cementitious materials) there are typically four main types Calcium silicate hydrate this is the main reaction product and is the main source of concrete strength. It is often abbreviated, using cement chemists' notation, to C S H, the dashes indicating.
