Replacement kit for cement mill gearboxes

Improvements to cement mill operation via installation of planetary gearboxes as “replacement kits”, have recently proven to be very successful, due to quick return on investments thanks to the immediate achievement of higher efficiency and improvement in mill operation. The installation of a “replacement kit” gearbox in most cases includes the utilization of the existing foundation by installation of “tailor made“ intermediate frame or adaptation to the gearbox casing. With this concept of customized solutions, the cement plant saves time and money, as the erection time of the new “replacement kit” gearbox is limited to a time frame of maximum 2-3 weeks. Cost optimization is further achieved by possible utilization of the existing auxiliary drives as well as no running in time. Finally, no displacement of the main motor is required due to the compact design of the 2-stage planetary gearbox. The overall improvement in service life for cement mill “replacement kits” gearboxes along with optimization of maintenance cost, is shown based on actual recent installations
