ABSTRACT:
A powder sprayer having a housing for containing a quantity of powder, a rotatable roller for metering the discharge of powder from the housing, a powder supply hopper remote from the housing, first and second conduits connecting the powder supply and housing, and a selectively operable regenerative type blower disposed in one of the conduits. The first and second conduits, blower, housing, and supply hopper define a closed loop through which air and powder may be circulated with relatively low-pressure, high air-flow operation for reliably transferring powder from the supply hopper to the housing without the tendency for clogging. In one embodiment, the supply hopper has an associated mixing chamber within which powder is pneumatically agitated for creating a relatively rich, substantially constant air-powder mixture for direction to the sprayer housing. In another embodiment, a dispensing cylinder is employed for directing controlled quantities of powder from the supply hopper into one of the conduits of the closed loop for mixing with the air flow and direction to the sprayer housing.
