As cement producers continually seek reduced energy consumption and lower maintenance costs, two emerging trends are changing the face of cement production: the use of grinding stations that support variable feed materials and more widespread use of vertical roller mills (VRMs). Cement producers in India, Nepal and Bangladesh demonstrate the success of using VRMs.
In case study 2, following the change of the bearings of the grinding rolls, the plant team was looking for a way to reduce the risk of bearing failure. 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.
Dec 01, 2017· Grinding cement requires a great deal of energy. As the fineness of the cement increases, it needs more energy to grind it. But every cement quality band has a certain fineness requirement. In one example mill, we consider the fineness and the energy consumed for eleven months for a cement mill.
