    A disadvantage is that the fuel mill has to run all the time: if it breaks down, the kiln has to stop if no backup system is available. In indirect firing, the fuel is ground by an intermittently run mill, and the fine product is stored in a silo of sufficient size to supply the kiln though fuel mill stoppage periods.
