Particulate material delivery apparatus comprising: a measuring device for separating a predetermined quantity of particulate material from a particulate material supply; a first valve which is responsive to a single input signal and which regulates a control fluid and a delivery fluid; an actuator for shifting the measuring device between measuring and delivery positions in response to a pressure signal from the first valve; and a control apparatus for dispensing a pressurized delivery fluid for a variable, predetermined interval of time in response to a pressure signal from the first valve. Also, a method for delivering measured charges of a particulate material, comprising the steps of discharging one charge of the material to a first location, measuring a second charge of the material, and a delivering the first charge to a remote location while measuring the second charge. |
