<p>Apparatus for providing a continuous flow of fluent particulate material suspended in a gaseous stream from a bulk source. The pneumatically powered and controlled apparatus includes a material receiving chamber intermittently replenishing a second chamber operable to maintain a third or material dispensing chamber adequately charged at all times. The apparatus controls are responsive to the material level sensing means in the second chamber to initiate a recharging cycle when the material therein falls below a predetermined level.</p> |
