Controlled delivery plant for powdered goods, e.g. coal powder - has at least two outlet pipes for silo feeding delivery cylinder with aerated exit nozzle for discharge
A controllable plant for delivering powdered goods in metered quantities has a silo with two or more outlet pipes at the bottom, each one connected to a delivery cylinder whose piston in turn is driven by a hydraulic cylinder. The content of the delivery cylinder is aerated and accelerated by transport gas pressure through a conical nozzle on the end, from where it passes to a feed pipe. The silo is filled through a valve at the top. There is also a filter on the top which releases gas to the atmosphere for 5-10 mbar overpressure. The outlet pipes have rubber seals and act like sieves, with vibrators attached to their outside to assist the flow of the powder. ADVANTAGE - Controlled separation of two or more different kinds of powdered goods in single plant, with high efficiency and low cost.
