5.Troubleshooting

Phenomena Possible Reasons Solutions

Defect of fuses;
Motor will not start Inspect by electrician
contactors or button
Motor is running, rotor Damaged gear Check up one by one
will not turn Square rod in rotor
defective Replace rotor

Rotor does not turn in Wrong connection of
direction for arrow phases Invert phase by change over switch
Check Champing Device. Clear the
Clamping Device is too material between Rotor and sealing

loose
Air leaks between plate, then tighten.
Rotor and Sealing Rotor Plate is in bad Check Rotor Plate, if it is carved,
Plate conditions Polish it or change a new one
Sealing plates is in bad Check Sealing plates, if it is grooves,
conditions Polish it or change a new one

Stop the machine and close the air
valves. If Vortex Stream Implement is
Ratio of w/c is too high blocked, dismount Conveying Hose,
Rotor, vortex stream clean Vortex Stream Implement and
Implement or Rotor, and then lower W/C ratio
conveying hose

blockage The cross section area of Chang a new pipe with a larger cross
air inlet pipe is too small section or change a larger air
or Air supply is

insufficient. compressor

If conveying hose is blocked, stops the
machine, close air valve, dismount
conveying hose from Vortex Stream
Implement, open air valve to blow the
remaining material in Rotor out, then
check the conveying hose. Strike the
blocked position to make the blocked
material loose or draw it out. (Note:
Oversized aggregate reduce the conveying pressure to zero
Rotor, vortex stream before dismounting Vortex Stream
Implement or Implement).
conveying hose Now re-connected conveying hose to
blockage
Vertex Stream Implement and blow the
material out .If the conveying distance
is over 40m,resolve the problem every
20m separately.
Stop machine and air supply. If Rotor
chambers Implement is blocked, open
Air conveying pressure is the turnover frame, open Rotor, and

too low then clean Rotor Chambers with brush,

raise air pressure.
Rotor chambers or Vortex
Stream Implement is Refers to blocking solution item
Output Capacity blocked.
declines Air valve is mis-mounted Reduce pressure loss. Re-install air

(too high pressure loss) valve
