The raw material grinding system is equipped with a ball mill (diameter = 5m, drying chamber length=2.2 and grinding chamber length=8.22m). The nominal capacity of the mill is 180t/h, the fineness of the product is 10% residual on 90μm sieve and moisture content in the raw meal is less than 1%.
Normally the grindability of the diverse constituents in the raw mix is different. Therefore it can be efficient to grind the raw material components separately. The most common application of this would be separate grinding of sand or slag, which are both much harder to grind and more abrasive than traditional raw materials.
