| When a particulate material is admitted to a storage vessel (10), it is passed through an electrode system (12, 14), the electrodes have a sieve like construction to allow the material to pass therethrough. A voltage source and signal generator (16) applies a potential difference betwen electrodes (12 and 14) to create an electric field between the electrodes which stops the passage of the material between the electrodes. Consequently a mass of material is held back by the electrodes. The electric field is controlled by the voltage source and signal generator (16) to release the held back mass of material intermittently. This avoids the formation of a cone of material in the storage vessel and improves the distribution of the particles by preventing the segregation of particles caused by the coarser particles rolling down the sides ofa cone of material. | ||||||

Apparatus for the control of particulate material flow without the need for moving parts or external components comprises a duct through which said material is to flow having positioned in the lumen thereof an upstream electrode (2) and a downstream electrode (3) for establishing an electric field in the path (F) of flowing material, the structure of the downstream electrode (3) being of greater complexity than that of the upstream electrode (22), the inner surface of the duct (1) defining the lumen in the region of the electrodes being substantially dielectric in character, and the geometry and arrangement of the electrodes being such that (a) particle flow past the downstream electrode (3) may be impeded upon application of the electric field, and (b) flow past the upstream electrode (2) is not disturbed significantly by the upstream electrode (2) so as to avoid transformation of dense phase flow to lean phase flow, thereby maintaining interparticle and particle-electrode contact. |
