to clean the dust covering on the filter cloth and hopper inner wall. Then, the
blower will start again. When lacking materials, the alarm light (9) on control box
(11) will be on to sound an alarm. The equioment equipped with air acculamtor
can increase air storage capacity to reinforce the dedusting efficiency of the auto
dust cleaner.

Picture 2-2: Working Principle of SAL-U-E(EA)
After starting the machine, blower (2) begins to vacuumize material hopper (4). At
the same time, the non-return flap (6) is closed. Materials in the storage bin will go
into material hopper (4) from material inlet pipe (3) under differential pressure.
When material conveying is completed, the blower will stop working. Materials will
then fall down due to gravity. When magnetic proximity switch (8) detects that
there is no material left in the hopper, the solenoid valve (13) will open. Thus, the
