ABSTRACT:
A bin for holding a granular material has a conveyor belt in the bottom thereof. A plurality of separate conduits are in communication with the bin with each of the conduits having a discharge end. The conveyor belt meters the granular material from the bin into the conduits. A fan is provided for supplying flowing air through the conduits to blow granular material towards the discharge ends. Each conduit has a curved portion formed therein upstream from the discharge ends. Sensors are located in each of the curved portions to measure the centrifugal force of granular material moving through the conduits towards the discharge ends. Pivotal walls are provided in each conduit to adjust the flow of granular material therethrough. A microprocessor is connected to the sensors and the actuator to sense variations in the centrifugal force measured by the sensors, and to adjust the pivotal walls in one or more of the conduits to equalize the flow of granular material through the conduits. The method comprises the use of a microprocessor to determine the quantity of flow of granular material through each of the conduits by the input of sensors in the conduits, then comparing the quantity of flow of granular material for each of the conduits to determine variations of flow among the conduits; and adjusting the flow of granular material through the conduits to cause a substantially equal quantity of granular material to flow out of the discharge ends.
