Andritz Brasil Ltda., a member of the Andritz Group, will carry out partial modernization of lime kiln B for Suzano Aracruz, Brazil, as part of a customized project for the white liquor production plant. Lime kiln B has the capacity to process 580 tons of lime per day.
This project aims to restore the mill’s equipment to its original condition, replacing used and worn components and thus eliminating all the mechanical damage detected over the years during inspections carried out by Andritz. The renovation project will commence in September 2022 during the mill’s scheduled shutdown, with operations resuming at the end of October 2022.
The Andritz scope of supply includes the replacement of the lime kiln cooler (sector cooler) as well as the installation of a new heavy shell and riding ring on the hot end pier, and installation of the burner tip and shim plates for the cold end pier. In addition to replacing the used parts, the services also include a new girth gear pinion and springs, reversal of the girth gear, machining of two carrying rollers on hot end pier and a mechanical diagnostic (hot alignment) of the kiln.
Luiz Gustavo Leite, Product Manager at Andritz, says: “The equipment, which dates back to the 1990s, has already undergone several revisions. In this update, we will use the most advanced materials and design to renew machinery that was at the end of its useful life. The equipment to be installed will have the best material and technology available today.”
