Several different types of kilns are used for the calcination process. these kilns can be rotary kilns or shaft kilns. the type of the kiln to be selected strongly depend on the characteristics of the raw dolomite, anticipated production rate, cost of fuel, investment costs, available fuel, local conditions, infrastructure and other things.

Lime kilns can be categorized into three groups: rotary kilns, vertical kilns, and miscellaneous. about 90 percent of commercial lime capacity in the u.s. is calcined in rotary kilns. most of the remaining capacity is processed with vertical kilns (vertical kilns are more common in captive supply facilities), and small quantities are processed.

Manufacturing process dead burnt refractory dolomite is produced in rotary kilns. generally highgrade dolomite, containing combined impurities less than 3, is selected for dead burning. as it is difficult to densify high purity dolomite in a rotary kiln, it is customary to use some mineralizers to facilitate dead burning.

The temperature required for the decomposition of dolomite and dolomitic limestone is usually in the range of 500 deg c to 750 deg c. the smaller size limestone is more suitable for calcination in rotary kilns and it allows optimum residence time. the lower calcining temperature also allows less fuel consumption.

Most of the plants in india use dri processa solid state direct reduction process by which iron ore is reduced to sponge without phase change (figure 1). raw material mixiron ore, dolomite and coal are fed to one end of rotary kiln and product sponge iron along with char is taken out from the other end. apart from this, primary.
