The coal mill for line 3 of the cement plant will ensure the fuel supply and is designed for grinding coal and pet coke with a capacity of 54 tph of mixed coal or 34 t/h of pet coke. The grist is ground to a fineness of 12 % (coal) or 3 % (pet coke) sieving residue with 90 µm.
The scope of supply also includes an LSKS-classifier and corresponding filters, blowers, an inertisation unit, the gas analysis and the main drives – all components are to be delivered before the end of the 2017.
One benefit is that the coal mill operates with a low differential pressure and therefore has a significantly lower energy consumption than typical solutions. In addition the Eagle Cement Corporation (ECC) was impressed by the distinctly good price-performance ratio and the close customer contact developed over years.
The cement plant in San Ildefonso has been operating since 2010.
