DSS055: Coal Mill Safety In Cement Production …
While this is not standard practice in cement production, cement plants in countries like India are often located far away from energy sources, so they rely on their own sources. Power generation typically involves direct firing systems. There is an air swept mill with direct pneumatic conveying through to the burners. The risk of explosions is more or less reduced to an explosion inside the mill, which …
