specifications and models of rotary kiln

Rotary kilns also known as rotary calciners are used to heat solids to a predetermined temperature in order to create a chemical andor physical reaction The two basic types of rotary kilns direct fired and indirect fired calciners can be found supporting processes in mineral agriculture and other material processing industries

Rotary kilns work by processing material in a rotating drum at high temperatures for a specified retention time to cause a physical change or chemical reaction in the material being processed The kiln is set at a slight slope to assist in moving material through the drum

Onedimensional kiln model The kiln model applied in this work was developed by Hatch over a number of years and has been used for several rotary kiln projects It has its roots in a FORTRAN program that was developed by Venkateswaran 1978 to study the reduction of iron ore The original software was used to model the operation of a 35 m
