Feb 04, 2016 The raw mill contains two chambers, separated by diaphragm, namely a drying chamber and a grinding chamber. The hot gases coming from a preheater (preheater / kiln system) enter the mill and are used in raw mills for drying. Then the drying materials enter the grinding chamber of raw mills for fine grinding.

One of the earliest types of grit removal systems, horizontal flow (also known as velocity controlled) grit chambers use physical controls and chamber geometry, such as proportional weirs and rectangular control sections, to vary the depth of flow and maintain the velocity within the chamber at a constant 1 foot per second (fps).
