Trickle valve assembly and a method of supplying particulate material through such trickle valve assembly

Abstract

The present invention concerns a trickle valve assembly for supplying particulate material exiting the bottom of a separating cyclone, comprising a separating cyclone outlet conduit having a bottom end with an inclined valve seat and a pivotable valve plate assembly with a valve plate pivoting about a valve hinge and a counter-weight on the opposite side of valve hinge, wherein the outlet conduit is provided with at least one gas inlet above the inclined valve seat which is in fluid communication with a supply of pressurised gas, such as a pressurised air supply.
