Ring deposits are common problems in rotary kiln operations. The ring is constantly subjected to thermal and mechanical wear counteracting the growth of the ring. If the ring hardens or if the growth of the ring is too rapid the kiln needs to be shut down and the ring removed reducing the operational time and profitability of the process. In the present study ring deposits from a limestone

Chemical Composition of Cement The raw materials used for the manufacture of cement consist mainly of lime silica alumina and iron oxide. These oxides interact with one another in the kiln at high temperature to form more complex compounds. The
This secondary dross is used for making calcium aluminate by sintering with limestone CaCO 3 in a rotary kiln. Tests conducted by Yang and coworkers 2004 have shown that the calcium aluminate flux thus produced has high melting rate and good desulfuriation capacity. It could well replace calcium fluoride as flux in steel production
