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.
Fig.8 compares the optimum composition between 1 m and 2 m diameters for the three feed sizes at different size reduction ratios.As expected, the fractions of 50.8 mm balls are lower for the 2 m diameter mills in all cases.This confirms that it is desirable to reduce the size and amount of the larger balls for mills with larger diameters.
Cement milling.The cement mills use steel balls of various sizes to grind the clinker, along with a small quantity of gypsum to a fine powder, which is then called cement.Without gypsum, cement would flash set when water is added and gypsum is therefore required to control setting times.
Grain size, it is necessary to have a definite number of the biggest balls in the charge, and with the decreased grain size, the necessary ball size also decreases olejnik, 2010 2011.For each grain size there is an optimal ball size trumic et.Al., 2007.The bigger ball in relation to the optimal one will have an excess energy, and.
