Abstract
A rotary kiln for pyroprocessing particulate material includes a cylindrical kiln shell supported for rotation about a longitudinal central axis. The kiln has a discharge opening that includes a lump breaker system. The lump breaker system includes multiple insert retainers mounted to the shell and positioned along the inner circumference of the rotary kiln. Each insert retainer includes multiple mounting slots for receiving breaker inserts that can be easily removed and replaced when worn. Each of the breaker inserts can be individually removed from its respective retainer without removing either the retainer or the layer of refractory in the rotary kiln.
