Rotary dryers are often used to process bulk materials and powders, fed continuously into the dryer's drum, along with hot air. A rotary dryer's drum rotates, using lifting flights to carry particles upwards. Near the drum's top, particles come off the lifting flight and fall through a heated air stream. The rotary dryer's drum is at a ...

In India, the wet process has been replaced to a wide extent by the dry process, mainly for fuel and heat economy. However, air pollution is reduced in the wet and semi-dry processes. Dry process (modem technology) is now preferred and adopted in most of the cement industries due to the following reasons :
Compaction is typically a dry process, meaning a liquid binder is not used to aid in granule formation, and therefore, no drying step is necessary. ... Glazing is a finishing step implemented after compaction and is often carried out in a rotary dryer (or in other cases a pugmill mixer). By spraying a small amount of water onto hot granules in ...
A schematic of the RKEF process with rotary dryer, rotary kiln and electric furnace is shown in Fig. 1.
