Henan kefid Science & Technology Co., Ltd. was founded in 1987 dedicated to the crushing and screening equipment and industrial milling equipment R & D, production, milling experts years of practical experience, summed up the  Raymond  mill‘s common problems and its solution.

There are some kinds of Raymond Mill Frequently Asked Questions:

1, the mill machine temperature rise, the host current is too large，
Weak winds;
2, the feeding amount is low or even no material;
3, the material is too coarse or too small to meet the requirements of
the finished product;
4，Roller bearing is seriously damaged;
5, Transmission system’s temperature is too high
6, The host caused too much noise , fan vibratio’s amplitude is such large

Pay attention to  the feed rate, especially  the severe wear of the blade,
It may led to deal with the shovel can not afford the materials or anchor bolts
to loosen the roller mill ring deformation serious to see if the blades
have accumulated powder or damage, check the oil viscosity and
temperature, the number of re-view analysis of the blades wear and
appropriate off a small fan for the wind, pay attention to feeding
excessive duct leads to the material can not keep up and blockage, caused
by poor pipe exhaust, so that air circulation led to machine temperature
is too high, the fan current drops, check the locks powder for the
adjustment in place, sealing leakage or found the leak source blade,and so on.
