Lafarge North America has contracted Gebr. Pfeiffer Inc. to supply an MVR vertical roller mill as part of an overall modernization project underway at its Ravena plant in New York. The project will replace the current wet process kiln with a dry line, allowing the plant to cut emissions and also increase its capacity.
A MVR 6000 R-6 will be installed in a complete new line at the plant, replacing two existing raw material mills. The contract also includes a 5600 kW motor, engineering, supply and related services. Commissioning for this project is planned for the middle of 2016.
The second contact is for an MVR 5000 R-4 vertical roller mill at Lafarge’s Exshaw plant in Alberta, Canada. The 109-year-old Exshaw plant is modernizing and expanding to take advantage of growing cement demand in the region. Included in the contract is an MVR 5000 R-4 vertical raw mill, 3300 kW motor, engineering, supply and related services. Commissioning is scheduled for early 2015.
Gebr. Pfeiffer’s newly developed MVR roller mill for grinding cement raw material, cement clinker and additives with an installed power of up to 12,000 kW was specifically designed to meet the needs at plants like Lafarge Exshaw and Lafarge Ravena – where energy efficiency, modernization and increased capacity are a priority. Some of the advantages of the MVR roller mill include: Short change-over time from direct to compound operation; modular design; optimum, symmetric design of wear parts and modern maintenance concepts; low capital cost; and low electric energy consumption.
