The pre-heating tower provides benefits. It saves considerable amounts of energy. CQI is the only cement plant in the Province of Quebec to have invested in this type of equipment. At the pre-heating tower, a series of cyclones stacked on each other transfer the energy between the hot gas and the raw meal.

Precalciner, also known as cement calciner, is a kind of high-efficiency direct combustion solid-gas heat exchange cement equipment. It disperses and suspends cement raw meal powder in airflow, making fuel combustion and calcium carbonate decomposition happen in a short time (generally 1.5 ~ 3 seconds).

Cyclone preheaters are also called suspension preheaters. In the new dry process of cement manufacturing, the raw meal must be preheated in the preheater before entering the rotary kiln for calcining.The quality of the preheater in a cement plant directly affects the stability of calcining temperature and cement clinker quality in the kiln.

Materials fed to the pre-heater tower are allowed to pass through a four stage suspension pre-heater which consists of several cyclones. The cyclonic action is generated with the help of suction of pre-heater fan. The hot gases from the kiln are sucked and passed such that the materials are heated to a temperature of about 300 to 400 °C at

Kiln preheater towers provide heat transfer from hot gases to kiln feed material. The counterflow of gases and material takes place in cyclones, referred to as stages, in the preheat tower. As material flows from the top to bottom of the tower, it is exposed to increasingly higher temperatures as it is prepared to enter the kiln.

New production lines using 6-stage or 7-stage cement kiln preheaters benefit from a low pressure drop design. The redesigned pre-decomposition system minimizes resistance. Each stage's pressure drop can be controlled at 600-800 Pa. When the production line reaches its designed feed rate, the first-stage outlet pressure drop stays below 5500 Pa.
