Expanded Shale (and Slate)

2007-7-17  Most of shale used for construction is used in the manufacture of bricks. Not all shale is suitable for brick, and even fewer deposits are suitable for expanded shale production. The shale must contain minerals (mostly carbonates) that will produce gas at the same temperature as the shale begins to sinter (soften prior to melting).

Production Process Norlite Agg

The expanded shale is then discharged from the kiln onto an air quenched traveling grate cooler. The cooler serves two purposes. One is to cool the newly expanded shale down so it can be easily handled by conventional means, and the other purpose is to preheat the large volumes of air that are needed in the process.
