The latest concept for continuous blending system is to use flat bottom continuous blending silo to blend dry, pulverized free flowing materials on a continuous basis using the maximum power of gravity force and minimizing the need of high rate of fluidisation for low power consumption. Principally the silo is divided in three distinct regions each with different area where material is withdrawn from each region at varying rates.
Aeration is used to selectively withdraw material from different sectors resulting in low specific power consumption, as only few sectors are aerated at any given time.
This silo is ideally suitable for new projects as well as for retrofit silos with poor blending system or for conversion of batch blending silo system into Continuous Blending Silo.
