Manufacture of Cement. To manufacture cement first of all limestone is added into the clay in proportion of 3:1 by weight. This mixture of limestone and clay is then dried and crushed to get a fine powder called 'raw meal'.The raw meal is then added into a rotary kiln through a hopper as shown in figure.
