Continuous blending involves simultaneous feeding of the silo, overflow to a second silo and final discharge to kiln feed. Modern equipment generally uses continuous CF silos, each having capacity of more than 24hours' kiln feed and yielding a blending ratio (or 'blending factor') of 48, or around 23 for older silos.
