    摘要: A dry granular material transfer system and method for transfer of granular material such as sand in a dry state through a hose using pressurized air. On a base platform, a conveyor subsystem moves granular material placed on a lower portion to a higher portion while separating clumped material and allowing rocks and debris to fall away, spreading the granular material in a thin layer for ejection at the highest level. A containment subsystem receives granular material and contains the downward fall of material. A portioning subsystem has a turntable with blow-through chambers which receive granular material and move into line with an air inflow tube and air-material outflow tube, and the air-material mixture is blown through the air-material outflow tube and through a transfer hose.
