2. Structure Characteristics and Working Principle
2.1 Main Functions
SAL-UG series "Euro" Separate-vacuum hopper Loaders are suitable for
conveying plastic granules over long distance. Utilizing high efficiency vacuum
blower to produce vacuum in material hopper, plastic materials will then be fed
into material hopper by outside pressure.

Picture 2-1: Working Principle
After the main power switch (7) is turned to the right, and the control box (8) is
powred on, the blower (2) starts working, causing negative pressure vacuum to be
generated in the hopper (14). Meanwhile, the discharge plate (16) is closed, and
the materials (15) in the material storage tank enter the hopper due to the air
pressure difference from the feeding pipe (13). After the suction time is over, the

11(29)
blower (2) stops running, and the materials (15) will fall due to their own weight.
When the magnetic reed switch (17) detects that there is no material, the blower (2)
will start again. When the material can’t be sucked for three times, the control box
(8) will judge that the hopper (14) is short of material, and the alarm light (9) on the
electric control box (8) will light up to alert.
During the blower (2)’s running, the airflow in the suction port (6) through the filter
barrel cyclone device to enter the filter (11) to filtrate the dust and the dust
adhering on the surface of the filter (11). After the blower (2)’s suction, the control
box (8) will send a spraying signal to the spraying solenoid valve (10) to start work.
Then, the high pressure air will directly spray a large amount of compressed gas
into the spraying device (12), thus generating an outward impact airflow on the
filter (11). The air will be discharged into the reverse spraying filter (10) and to the
outside through the suction port, enabling the filter (11) to remove the dust
adhering on the surface into the dust collective hopper (4).

3. Installation and Debugging
This series of models only could be applied in working environment with good
ventilation.
Read this chapter carefully before installation of the machine. Install the
machine by following steps.
Power supply should be fixed by qualified technicians!

3.1.2 Installation Steps
1) Put the main body of the machine at a proper place and connect it with power
supply.
2) Install material hopper onto the dryer and connect it with signal wires from the
main body.
3) Use steel wire conveying hose to connect air suction pipe (A) on material

13(29)
hopper with air suction pipe (D) on main body. Material suction (B) should be
connected with material suction probe (B) in material storage bin.
4) Connect high pressure air pipe (C) with air supply (pressure at 3~6kg/cm2).
3.1.3 Power Supply
Make sure that the power supply conforms to required specifications before
installation. SAL-UG (E) Series should be connected with 3Φ400V 50Hz Power
supply or other specifications if required.
Note: Make sure main switch is turned off before you connect
the power.
