The BGM comminution circuit includes a primary crushing stage with a gyratory crusher and a two grinding circuits using a Semi-Autogenous Grinding (SAG) mill and a ball mill.

Induced by the direct input of mechanical energy, crushing and grinding can modulate the target solids via different modes of mechanical actions, including impact, compression, shearing, stretching, and crushing (Balaž et al., 2013; He et al., 2020).

The optimal size of the raw material after crushing is about 20 mm–80mm. After the grinding process, the size of the crushed raw material can be reduced further to between 0.2 mm and 25 mm, using a crusher for ease of transport via the stacker conveyors. It is then stored in a stockpile before transport to the cement plant.
