Fine powders like fly-ash, potato starch and filter dust tend will fluidize when handled. To respond to this specific issue of our customers, ESI Eurosilo has developed and deployed the shutter column system.
For recycling plants that produce very fine electric arc furnace dust (EAFD), we have built silos that are equipped with the shutter column. The center column of this reclaim system is equipped with shutters that can be programmed to open and close during the filling process of the silo. In this way the products can be handled without any problem.
