Heat transfer is achieved through intimate contact between the hot gases and the fine clay particles, creating improved heat recuperation for the system when compared to a rotary kiln. An induced draft process fan controls the transport in the preheat/calcination sections, while a baghouse filter is applied for dedusting.
