2.1 Main Functions
SAL-UGP "Euro" separate-vacuum hopper loader are applicable to convey the
mixture of plastic granule and powder or all powders. It makes good use of
motor generated vacuum to form a pressure gap within hopper, by which
means to convey.

Picture 2-1:SAL-UGP Working Principle
After starting the machine, blower (2) begins to work to produce high-pressure
vacuum inside of material hopper (15), meanwhile close the reverse stopping
flap (17). Materials will be drawn into material hopper by pressure difference
through material inlet (13). When material suction is completed, motor stops
