    Raw milling Question 5. In our plant we have a typical problem of high wear rate of mill liners. The basic reason identified is the percentage of free silica in silica (one of the components of raw meal) is very high about 50 per cent and the consumption of this material is also very high (around 14 per cent) due the very high quality of limestone (low grade limestone clay or shale is not
