There are usually four kinds of VRMs in the cement production line, including raw meal mill, coal mill, Clinker Mill and cement mill, and the vertical mill occupies a large energy consumption unit. Therefore, it is necessary to optimize the multiobjective parameters of the VRM in order to improve the grinding performance and reduce energy ...

Torsional vibration in ball mills can be a serious problem even leading to failure. In the design of such mills it is therefore important to be able to design them so that such vibration will not be a problem. It is thus desirable to be able to model the torsional vibration of a rotating system which includes a ball mill.

Over the past 30 years, roller mills have been rapidly employed and widely used to process raw materials in the cement industries because of their superior high efficiency [1], [2], [3]. Recently, roller mills have come to be adapted to the grinding of other materials such as ceramic, filler material, etc. due to their power saving capability [4].

In cement mills, ventilation is a critical key for maintaining temperature and material transportation. However, relationships between operational variables and ventilation factors for an industrial cement ball mill were not addressed until today. This investigation is going to fill this gap based on a newly developed concept named "conscious laboratory (CL)".

With that in mind, the dominant sources at a cement plant, with regard to environmental noise, are often one or more of the following: Crushers. Rock falling from conveyors onto primary surge piles. Kiln shell cooling fans. Kiln and mill exhaust stacks. Clinker cooler heat exchanger fans. Vacuum Trucks.

The vibration signal analysis for lab model sag mill is same as that of ball mill, but the frequency of operation of vibration signal and impact strengths are different [8]. Sag mill will require a higher value of g and BW of the sensor due to higher stiffness compared to that of ball mill (as the length of the mills is accounted).

The unbalance had caused an excessive vibration, which reduced hourly cement output, by approximately 18%, over a period of 53 days. Upon the suspicion of unbalance a visual inspection and cleaning of the fan impeller was recommended as a first aid treatment before detailed vibration analysis and rotor balancing was carried out by the experts.
