Lafarge Ravena cement plant
Lafarge North America Inc. has opted for the innovative MVR technology for its modernisation project at the Ravena cement plant in New York. The contract was signed with Gebr. Pfeiffer, Inc., a subsidiary of Gebr. Pfeiffer SE. The project, which will be featured in the April issue of World Cement, aims to modernise the current ‘wet’ process, replacing it with a more energy efficient dry process, and also increasing capacity. Gebr. Pfeiffer’s MVR 6000 R-6 will be installed in a new line at the plant, replacing two raw material ‘slurry’ mills.
In addition to the vertical raw mill, Gebr. Pfeiffer’s contract includes a 5600 kW motor, engineering, supply and related services. Commissioning is planned for mid-2016.
Lafarge Exshaw cement plant
Across the border, the Exshaw plant in Alberta, Canada, has also opted for the MVR technology, contracting again with Gebr. Pfeiffer, Inc. for an MVR 5000 R-4 vertical roller mill. The 109-year-old Exshaw plant is modernising and expanding to take advantage of growing cement demand in the region.
Some of the advantages of the MVR roller mill include:
- Short change-over time from direct to compound operation.
- Modular design, i.e. optimum combination of housing cross-sections and geometry of grinding elements.
- Optimum, symmetric design of wear parts and modern maintenance concepts.
- Good partial load behaviour.
- Low capital cost.
- Low electric energy consumption.
- Highest availability.
- Favourable control behaviour.
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 next year.
