In modern cement production process, the raw material grinding has an important place, who
works stability, and the quality of the out raw materials will
directly affect the quality of the final cement product and grade.
Understanding the factors that affect the work efficiency of cement
ball mill can provide theoretical support for the control of cement ball mill in the production process.
The grinding effect is mainly determined by the following factors:
1 The process principle of grinding and the matching condition of
each equipment. In particular, the matching of the device is even
more important, if the matching is not reasonable, the grinding
effect will become very bad.
2 The formulation of realistic control schemes. At present in most
of the cement plant, the mill load mainly rely on manual control to
achieve. Due to the strong nonlinear, strong coupling and large
hysteresis characteristics of the cement ball mill, the artificial
control cannot meet the control requirements. Mainly reflected on
the following aspect:
Manual control entirely depends on the experience and proficiency
of the operator, when the operator experience is not enough for a
long time, it is easy to encounter unexpected situations to result
in full or empty grinding.
Manual operation is that all the work depend the judge roughly the
site, the process is often adjusted drastically for insurance
purposes, which can easily cause that production efficiency always
maintain at a lower level to lead to the frequent fluctuation of
mill load greatly. That lead to a direct consequence is that mill
grinding effect decreased, the rate of qualified products cannot be
guaranteed, mill in overload or under load greatly increases the
probability, resulting in serious loss of mill, power consumption
becomes larger, grinding body had to be replaced frequently. This
virtually increased the economic burden on the cement plant, such a
result is not willing to see each cement manufacturers.
Fault diagnosis based on pattern recognition and other methods is
worth further researching. Dong this can greatly reduce the
workload of the operator and maximize the number of production
caused by the failure of the number of times. It has a great
practical value and promotion value.
The grinding process plays an important role in the whole process
of cement production, the effect of grinding process control is good or bad, which has
a significant impact on energy saving and economic indicators of
the whole production process. There is a great development space
for cement ball mill whether it is from the technical or demand. We
should strive to do a good job of production technology updates
relying on technology to solve problems in production and maximize
