2. Structure Characteristics and Working Principle
SAL-430 / 460 series are suitable for conveying plastic granules. The blower
makes vacuum of material hopper by drawing the air out. Materials will then be
sent into material hopper.
Picture 2-1: Working Principle
1. Blower 2. Alarm light
3. Control box 4. Material inlet pipe
5. Storage hopper 6. Materials
7. Microswitch 8. Discharging plate
After starting the machine, blower(1) works, it makes the storage hopper(5)
generate the vacuum, discharging plate(8) closed, materials in the silo enter
into the storage hopper(5) through material inlet pipe (4) by air pressure
difference. When loading is finished, blower(1) stops rotating, materials(6) drop
off by gravity, when microswitch(7) detected there’s no material in the hopper,
blower(1) will start again. When material can’t be sucked or lack of material,
alarm light (2) on control box (3) will flicker for indication.

2.1 Main Electrical Components Description
2.1.1 Microswitch
It is used to give control signals to make the motor start working after discharge
of the material.

3. Installation and Debugging
This series of models only could be applied in working environment with good
ventilation.
Make a careful study of this chapter before installation. The machine must be
installed according to the steps below.
Power supply should be connected by qualified electricians.
3.1 Installation of SAL-430 / 460
Picture 3-1: Installation Methods (SAL-430/460)
1. Notes for 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 easymaintenance, it’ssuggested to leave 1m space around the
machine.
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.

15(29)
2. Pipe connection
As picture, mount the loader onto the hopper dryer and lock with screws.
Connect one end of the material pipe to inlet of loader and insert another
side to the storage tank.
3. Electrical Circuit Connection of SAL-430 / 460
Please connect SAL-430 / 460 series 230V model of machines with AC 3 ,
230V 50Hz power supply and earth wire, and for SAL-430 / 460 series 400V
model, please connect it with AC 3 , 400V 50Hz power supply and earth
wire. Please make sure that the main power is shut off when you
connect the machine with power supply!
3.2 Installation Space
During installation of the machine, keep at least 1m installation space around
the machine as shown by the picture.
Do not install the machine in a position crowded with other objects. This would
cause inconvenience to operation, maintenance and repair.
Do not sit on the machine.
Keep away flammable and explosive goods.
