Precalciner, Calciner In Cement Plant, Cement Calciner

The cement calciner makes the raw meal spread and suspension in the air flow, and ensure the fuel consumption and decarbonation happens in a short time. In the precalciner, the fuel combustion is carried out at the same time with the material endothermic reaction under the condition of turbulence, the fine particles of fuel float on one side and burn on the other side, making the whole furnace

Precalciner Calciner In Cement Plant, Cement Calciner

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). To some extent, it replaces part of the calcining work of a cement rotary kiln. In the
