Two are Polysius installations from Line 1, each with a capacity of 62t/hr. With Line 2 came cement mill 3, which has a capacity of 70t/hr. It is from IHI. Since we had high demand, in 2006 L&T India installed cement mill 4, which has a capacity of 150t/hr. At the moment we actually run some of the mills slightly above their rated capacities.
