US: Zanini Renk has received a repeat order from St. Marys Cement for four additional gearboxes at its Charlevoix, Michigan plant. In 2016, St. Marys Cement's Charlevoix plant began a US$130m upgrade to expand the plant's infrastructure. The project scope included adding a new finish mill, an additional kiln and a new coal grinding system. The 2016 upgrade at St. Marys Cement expanded the Charlevoix plant’s cement capacity from 1.4Mt/yr to 2Mt/yr.
The initial order for a Zanini Renk gearbox was for installation in its vertical roller mill. Zanini Renk completed the gearbox installation in 2022. The first new gearbox has been in operation since January 2023 and the other two new gearboxes will be delivered at the end of November 2024. Installation is expected to be completed by March 2025 and by April 2025.
