Abstract (en)
[origin: WO9856697A1] 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.
