The first rotary kiln was introduced to the cement industry by Frederik Ransome (1885) when he took out a patent in England titled "Improvements in Manufacture of Cement." The first of these rotary kilns were up to 2.0 m in diameter and 25 m long, with an "enormous" production of …
Kiln feed metering: Almost all modern cement plants have adopted an indirect weighing system like solid flow meter, rota-scale etc. with a dosing gate as a pre-feeder to feed kiln within a tolerance range of ± 2 %. However standalone volumetric system (like screw feeder) and gravimetric system (like weigh feeder) feedings are still existing in ...

Note that: The value of (F×FA) is equal to the summation of all fuel types used for clinker production, for example (F×FA) = (F×FA) kiln fuel type 1 + (F×FA) kiln fuel type 2 + (F×FA) calciner fuel. Thus, the amount of kiln feed should be weighed during a kiln test period (e.g. 24 h), in which the operation conditions are representative for the kiln operation during the whole …
