The chip is off-loaded and moved by conveyor belt to an intermediary stockpile.
From here, the chip is then moved to the preheater hopper where the chip needs to be preheated. First, it is loaded into the large hopper, and hot gas from the kiln at about 1000°C percolates through the chip.
After 4 hours in the preheater, large plungers push the hot chip into the upper portion of the rotary kiln. This preheating process is essential as it contributes markedly to the efficiency of converting limestone into lime.
