Central Inverted Cone - Air Assisted Gravity Blending. Multiple outlet gravity discharge combined with central cone construction gives advanced gravity blending and storage with a power consumption as low as 0.25 to 0.5 kWh / metric ton of cement raw meal.

Open Airslide® sections in the flat annulus ensure full clean-out when required.

Material enters the central bin via multiple Airslide® blending materials from different areas of the silo floor.

An arrangement of air valves activates sequential discharge and provides a continuous blending of materials from the side of the silo through a funnel effect.
