Abstract

One or several ejectors can be tapped off a single pressurised chamber in which a fluidised bed of powder is fed by a powder hopper; there is no interaction between the delivery characteristics of the ejectors since the depth of the fluidised bed and the pressure in the chamber are automatically maintained at predetermined levels despite sudden changes in demand. The arrangement is esp. suitable for the supply of pneumatically conveyed powder to electrostatic coating processes.
