United Cement Co of Nigeria (UNICEM) commissioned its new line at Mfamosing, Cross River State, in September 2016. Loesche has since announced its scope of supply for the project, including the LM70.4+4CS, its largest VRM built for grinding clinker.
With a pre-existing 2.5Mta capacity, UNICEM contracted Loesche to extend the plant with a further two vertical roller mills. A type LM60.4 mill was installed for the grinding of raw material at a rate of 500tph and the LM70.4+4CS which is designed for a capacity of more than 370tph to a fineness of 4700 Blaine.
To operate the new equipment a new drive system with operation power of up to 8800kW was necessary. This was organised in collaboration with Renk AG and Loesche.
