2. Structure Characteristics and Working Principle
2.1 Working Principle
SAL-910G series 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 air pressure.

Turn on the power switch (3), and set the suction time of hopper 1 (8) and
hopper 2 (9) on the touch panel. Press the start button, the high pressure blower
(4) works, the three-way valve (5)’s control suction inlet 1 (6) opens, the suction
inlet 2 (7) and discharge plate 1 (10) close, and the hopper 2 (9) begins to suck
the materials. After suction, the high pressure blower (4) stops running, and the

14(32)
materials in hopper 2(9) drop because of the gravity. When the micro switch (13)
detected no material in hopper 1 (8), the high pressure blower (4) works. At this
time, the solenoid valve switches, the three-way valve’s control suction inlet 2 (7)
opens, the discharge plate 2 (12) closes and the hopper 1 (8) starts to suck the
materials. After suction, if the photosensor swtich (11) detected no materials in
hopper 2 (9), the high pressure blower (4) will start to suck materials again by
switching the solenoid valve, and so on. When no materials can be sucked or in
shortage, the buzzer (2) on the control box (1) will alarm.
2.2 Options
Cyclone dust collector
Picture 2-2: ACF External Dimension
For SHR,SCH-6U/12U/24U and SICH-6U/12U/24U are optional
(Temperature redution is below 30℃within 30min).
SMH can be matched with SCH-12U/24U to facilitate the temporary storage
of materials.
2.3 Options
For folished hopper inside ones,add “P”at the end of model code.
It is suggested to opt cyclone dust collector to reduce
cleaning times of filter when regrind material occupies
over 30% of total raw material.

3. Installation Layout
3.1 Installation and Positioning
1)
Machine just can be mounted in vertical position. Make sure there’s no
pipe, fixed structure or other objects above the installing location and around
the machine which may block machine’s installation, hit objects or injure
human person.
2) For easy maintenance, it’ssuggested to leave 1m space around themachine.
3) Machine should be placed on water-level surface. If it needs to be mounted
on a higher surface (e.g. the scaffold or the interlayer), should ensure its
structure and size could bear the weight and size of the machine.
3.2 Power Connection
1) Make sure the voltage and frequency of the power source comply with
those indicated on the manufacturer nameplate that attached to the
machine.
2) Power cable and earth connection should conform to your local
regulations.
3) Use independent electrical wires and power switch. Diameter of electrical
wire should not be less than those used in the control box.
4) The power cable connection terminals should be tightened securely.
5) The machine requires 3-phase 3-wire power source, connect the power
lead (L1, L2，L3) to the live wires, and the earth (PE) to the ground.
6) Power supply requirements:
Main power voltage: +/- 5%
Main power frequency: +/- 2%
7) Please refer to electrical drawing of each model to get the detailed
power supply specifications

3.5 Installation Steps

19(32)
1) Place the SAL-910G/920G2 in proper place
2) Install the photosensor hopper receiver and vacuum hopper receiver, and
connect the signal wire to the loader SAL-910G/920G2. (The hopper with
high use rate shall be connected to position No. 1 first).
3) Connect the photosensor hopper suction inlet and vacuum hopper suction
inlet to corresponding suction inlet of loader SAL-900G/900G2 with the steel
wire hose, and connect the vacuum hopper suction inlet and photosensor
hopper suction inlet to the suction box (usually under the dryer or storage
hopper).
3.6 Shut-off Suction Box
The shut-off valve is linked with the photosensor hopper receiver. When the
photosensor hopper receiver sucks materials, the shut-off valve will open for a
period of time (adjustable) and close immediately. Then, the loader will continue
to suck materials till all materials in the suction pipe are getting into the
photosensor hopper receiver.
1) Connect the signal line of the connection point on the suction box to the
signal connection point of the host shut-off valve.
2) Connect the suction box’s suction inlet and hopper’s feed port with the steel
wire hose.

1) Find the installation hole as shown in below Picture 3-6.
2) Remove the bolts.
3) Install the ACF-1 on the cover plate of SAL-G and locked with screws.
4) Connect the suction inlet of SAL-G’s host unit and ACF-1’s exhaust outlet
with the steel wire hose.
5) Connect the ACF-1’s air inlet and hopper’s suction inlet with the steel wire
hose.
