Lime kiln preheaters are used to "preheat" the limestone prior to the limestone being fed into the kiln. Hot kiln exit gases that might otherwise be exhausted to the environment are used to heat the limestone. This improves operating efficiency and reduces operating costs. Lime preheater floors are very abrasive service environments.

In suspension preheater kilns more alkalies remain for the time of burning in the kiln system and thus in the clinker, than in other types of rotary kilns. In the course of the burning process, alkalies in the amount of 0.6-2.2% K20 and 0.1-0.7% Na20 coming from the clay minerals of the raw mix and from the fuel, are transferred into the clinker.
The FL In-Line Calciner Preheater System offers a full capacity range for today's plants, up to 14,000 t/d or more. It can be built with single or multiple preheater strings with up to 6 cyclone stages.
