the safe removable rotary kiln

The alumina rotary kiln process is described as follows. Raw material slurry is sprayed into the rotary kiln from upper end (the kiln tail). At the lower end (the kiln head), the coal powders from the coal injector and the primary air from the air blower are mixed into bi-phase fuel flow, which is sprayed into the kiln head hood and combusts with the secondary air, which comes from the cooler.

ROTARY KILN Some questions and answers of CEMENT

Proper operation of a horizontal rotary kiln requires continual oversight and maintenance. A typical kiln is put under extreme stress under normal operations, and even minor maintenance issues can manifest in sub-optimal performance or even damage to the kiln itself. In particular, care must be taken to maintain the balance and alignment of a kiln.
