As
with other equipment, the ball mill in the course of the operation will
inevitably be a variety of failures, or due to man-made operating
factors, or equipment running wear and other reasons. Red Star machine that the face of equipment failure, the first thing to do is how to solve the problem.
Ball
mill slippage is not common, but if the normal wear and tear to a
certain thickness, tile lining and the spherical body can not be a good
combination, it will lead to equipment abrasions. Simple theoretical explanation may not let everyone a good
understanding, the following we have a concentrator ball mill sliding
bearing burning tile as an example to explain.
Plant
clinker ball mill in a normal operation, the feed hollow shaft suddenly
heat, the temperature is very high, up to 200 degrees, the hollow
surface of the hollow color blue, emergency stop check and found that
the surface of the tile tile has a lot of Babbit, Judgment tile surface is melted by high temperature. In the role of friction and pressure, was out of the tile mouth.
The
disintegration examination found that the alloy tile surface appears a
lot of scratches, the middle of a scratches very deep, but scratches the
bottom and the spherical body there are about two-thirds of the
thickness. Expert
analysis, the ball mill this problem occurs, because the hollow shaft
into the clinker temperature is too high, the corresponding hollow shaft
surface temperature is very high, dilute the viscosity of the oil,
forming a film, shaft and tile lining direct contact friction , Generate heat, the temperature rises sharply, melting the tile lining surface, causing scratches.
Faced with this situation, we usually have two ways to solve. One
is directly replace the spherical tile, which is the most simple and
most direct solution; the second is to repair the damaged tile lining. In
production we often encounter the problem: the workshop is tense and
orderly operation, suddenly a device failure, but this is the order to
be delivered, the production task is tight, but the number is not too
large, and this time There is no spare parts, this situation is often encountered by manufacturers problems. At this time, we need our team equipment for timely repair, so that orders can be delivered within a predetermined time.
Here we get to the story, talk about how to repair the damaged tile lining. Repair damaged wings need to have an experienced mechanic to scratch the filing of the filing treatment to make it smooth. On
the surface without damage, scraping the rules of the micro-oil tank,
repair tile mouth (that is, into the port), and then unloading the ball
mill grinding body and clinker, artificial grinding body on the tile
lining no-load grinding. To a certain extent, and the transmission part of the no-load test
run, a few hours later, into the grinding body and clinker with load
operation, observe all the normal can continue to use.
After
the equipment appears above, even after the normal use of the repair,
Red Star machine or to remind the user, the timely replacement of the
new spherical tile, because the equipment problems, the temporary repair
can not be used for too long, the timely replacement of new Ball tile surface, in order to ensure that your next production operation smoothly.
