Finding failureSep 06, 2017 · During mill operation roller surfaces wear down, which results in a higher dynamic load, peaks which exceed the nominal torque and, in general, an instable mill operation and lower performance. In many instances, bearing failures at the rolls are caused by excessive dynamics in the grinding process.

Energy efficiency of cement finish grinding in a dry batch ... · Dry grinding experiments on cement clinker were carried out using a laboratory batch ball mill equipped with torque measurement. The specific energy was found to be dependent on operating parameters and clinker environment. Additional compounds such as gypsum and pozzolanic tuff improve energy efficiency. The optimal parameters allowing maximising the energy efficiency factor were .
The operating principle of the ball mill · Ball mills characterized by high energy consumption. When the mill idles, the energy consumption is approximately equal to the energy consumption with full mill capacity. Therefore, the work of the mill with partial load conditions is unprofitable. Energy consumption for ball mills is a function of many factors: the physical properties of the ...

In discussion · With load measurements, for example torque measurements, we can detect critical overloads and load variations experienced by the gearbox. By correlating this information with the machine operating parameter, we find the root cause of high load peaks. In the case of cement mills, we often find that an inadequate feed causes high stress on the gearbox. In such cases, steps can be .
