For a flat bottom silo, a tight, scientifically designed aeration system is essential for power materials storage like cement, fly ash, and lime. This system must ensure the full automatic controlled aeration, automation of roots blower system, smooth unloading, high cement empty rate, and rare failure.
The cement silo has a tapered cone in the silo center to relieve pressure. The silo bottom circle discharging zone has a 10-12 degree angle with a horizontal floor and is divided into several discharging zones. When the air enters into the discharging zones, the cement, fly ash or other powder materials will flow into the pressure relief cone and unloaded, the inside silo cement, fly ash, or Other powder materials will swirling collapse down by material gravity and thus creating the effect of homogenization also.
The main equipment for the system is by open aeration chute, roots blower and its pneumatic piping system, needed gauges and meters, PLC control system. The system design must be adjusted or enhanced based on local temperature and moisture situations.
