A refractory lined rotary kiln is used for induration. In a straight grate, the grates cars have to go through the drying and induration zones. So, a deep bed of pellets with a hearth layer is required. The modern Grate-Kiln System will have a power requirement of less than 20 KWH/ton, while a straight grate system will use over 35 KWH/ton.

Contrary to straight-grate systems where one-half of the induration grate is returned empty to the charging station, the circular-grate design of a CPT plant means that the equipment utilization can be fully optimized. Not only can the required grate length for a given output be significantly reduced with CPT, energy costs are also reduced.
