2. Structure Characteristics and Working Principle
2.1 Working Principle
SAL-G 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.

7. Reed switch
8. Discharging plate
Turn on the machine, the high pressure blower(1)starts work, it makes storage
hopper (5) generate the vacuum. Discharging plate(8) closed, materials in silo
get into the storage hopper(5) through material inlet pipe(4) by air pressure.
When the loader finishes the work, high pressure blower(1) stop working,
materials (6) will drop off due to gravity. When the reed switch (7) detects
there
’
s no material, high pressure blower (1) will start working again. When the
loader can
’
t suck the matrial or material shortage, the buzzer(3) on control box(2)
will alarm.
