ABSTRACT:
A spraying system includes a screw conveyor to transmit material to be sprayed from a storage container to a spray nozzle. A predetermined torque is maintained on the screw to thereby maintain a predetermined pressure on the material within the conveyor, so that an instantaneous flow of material at a predetermined pressure can be obtained when the nozzle is opened. The pressure is preferably maintained by means of a hydraulic motor designed to stall at a predetermined torque. A heating jacket for housing heated oil surrounds the screw conveyor and provides heat necessary to maintain the material therein at a predetermined temperature.
