Wonder Cement has ordered its eighth vertical roller mill from Germany-based Gebr. Pfeiffer. A MPS 3070 BK type mill has been selected for grinding petroleum coke and coal. The throughput rate for pure petcoke grinding will be 40t/hr with a product fineness of 2% R 90µm. The mill will be equipped with an SLS 2900 BK type classifier. Due to the high abrasiveness of Indian coal, the mill and classifier will be designed with a correspondingly robust wear protection. The new mill will support the fourth 8000t/day production line at the producer’s plant at Tehsil Nimbahera, Chittorgarh in Rajasthan.

Most of the components of the coal mill will be manufactured by Gebr. Pfeiffer India including the housing and foundation parts, the grinding bowl and a large part of the force-transmitting parts. Delivery of the mill is scheduled for the end of 2021. Commissioning of the entire kiln line with the new grinding plant is scheduled for spring 2022.
