US: Gebr. Pfeiffer Inc., the US subsidiary of Germany's Gebr. Pfeiffer SE, has been contracted to supply a new raw material vertical roller mill for the Holcim (US) Hagerstown plant as part of a wider renovation project. The order was placed through KHD Humboldt Wedag, which is the engineering and equipment supplier for the Hagerstown plant modernisation. KHD has been contracted to modify the existing production line to increase the plant's potential production rate to approximately 2400t/day and to comply with the new NESHAP environmental regulations.
KHD's scope of supply begins with modifying the raw material feed system and continues through to the clinker handling system and storage hall. As part of the solution, a new raw material grinding mill, the MPS 3750 B, along with all related engineering services will be supplied by Gebr. Pfeiffer, Inc. The raw material grinding mill includes a rotary air lock with drive, MPS 3750 B mill, an SLS 3150 B high efficiency classifier and includes Gebr. Pfeiffer's patented 'Lift and Swing' technology.
Commissioning for this project is planned for mid-2016.
