High capacity particulate loader and transfer apparatus

A high capacity particulate loader having an intake hose on one sidewall thereof which communicates with a source of negative pressure formed by a multi-stage suction mechanism, to create a high suction, high volume and high speed air stream that draws particulate materials through the hose and propels them into a separation chamber where they separate from the air stream and are directed into a discharge auger assembly on the opposite sidewall of the loader. The multi-stage suction mechanism communicates with a separation chamber and/or a settling chamber, the settling chamber providing an area where dust or fine chaff from the suctioned particulate materials, which may be present in the air stream, can settle, through gravity, on a bottom surface of the settling chamber, thus avoiding contact with the blowers so as to prevent clogging of the blowers and rotor wear thereof.
