In the progress of produce, Raymond mill trouble is inevitable. To
optimize the produce progress, it is indispensable to know the common
trouble shooting. The following gives some trouble situations and
troubleshooting and you can check the machine yourself without
professional repair.
Common disorders Causes Ways to Fix
1. No powder output or low
capacity
(1) Powder-locking device is
not sealed-up.
(2) Shovels worn out.
(1) To check and make it
sealed-up.
(2) To replace the worn
shovels.
2. Powder too rough or too
fine
(1) Blades worn out and can
not take effect in grading.
(2) Air flow is improper.
(1) Replace the blades and
decrease airflow for finer
powder.
(2) Increase air flow if powder
is too fine.
3. The electric current and the
heat of the main motor goes
up, the current of the blower
comes down.
(1) Too much amount feeding,
the flow channel is blocked up,
pipes not working well.
(1) Reduce the feeding
amount, then clear-up the flow
channel.
(2) Reduce the moisture
through the pipeline.
4. Abnormal noise and too
much vibration of the grinder
(1) Too small amount of
feeding, uncoaxiality of the
grinder and transmission, no
gap between two couplings,
loosening of foundation bolts.
(2) Too hard material
processed.
(3) Rollers and rings distorted.
(1) Adjust the amount of
feeding, to guarantee
coaxiality, to adjust the gap
between the two couplings.
(2) Control the feeding size.
(3) Rollers and rings distorted.
5. Vibration of blower (1) Too much powder on
blades or imbalance arousing
by wear and tear of blades.
(2) Loosening of foundation
bolts.
(1) To get rid of powder on the
blades or replace them.
(2) To fasten the bolts.
6. Heat-up of transmission and
separator’s oil tank
(1) Oil is too sticky and too
thick, pump can not function
properly.
(1) Check and ensure the right
oil used.
(2) Check revolving direction
of the separator.
7. Powder’s entering into
roller assembly leads to
bearing easy to be worn out
(1) Shortage of oil or
breakdown of sealing ring.
(2) Lacking maintenance and
clearance for too long.
(1) Fill oil and change oil on
time.
(2) Clear up and replace oil-
seal regularly.
