Advanced Lime Kiln Plant Powers Guangxi Paper Mill's New Production Facility

Guangxi Botare Yuantrove Paper has partnered with global technology leader ANDRITZ to integrate an innovative lime kiln system into its newly established pulp mill located in Yugui Industrial Park, Guigang City, China. This state-of-the-art lime kiln installation represents a significant technological advancement for the paper mill, designed to meet the facility’s stringent operational specifications while delivering superior performance across multiple parameters.

Next-Generation Lime Kiln Technology Features

The lime kiln plant developed by ANDRITZ showcases cutting-edge engineering that prioritizes operational efficiency without compromising environmental standards. The system architecture emphasizes three core performance dimensions: minimal energy consumption, substantially reduced emissions, and maximized equipment availability. This comprehensive approach translates into lower operational costs and sustainable long-term performance for the paper mill’s lime recovery process.

The plant will process burnt lime at a capacity of 380 tons per day, providing consistent output to support the mill’s pulp production requirements. The lime kiln’s design incorporates advanced materials and process optimization to maintain peak performance even under demanding operational conditions.

Enhanced Lime Mud Processing and Environmental Benefits

A critical component of this lime kiln installation is the LimeDry lime mud filter technology, engineered to maximize dry solids recovery while ensuring highly efficient lime mud washing. This sophisticated filtration system significantly reduces total reduced sulfur (TRS) emissions in the lime kiln flue gases—a crucial environmental consideration for modern paper mills.

The integration of LimeDry technology with the main lime kiln plant creates a synergistic system that delivers dual benefits: improved operational efficiency through lower heat requirements and enhanced environmental performance through emission reduction. This comprehensive solution demonstrates how advanced lime kiln technology can balance productivity with sustainability requirements.

Project Significance and Strategic Partnership

The collaboration underscores Guangxi Botare Yuantrove Paper’s commitment to implementing world-class manufacturing standards in its new paper mill operations. ANDRITZ’s proven expertise in lime kiln systems and lime mud processing technologies made them the ideal technology partner for this strategic project. The contract was included in ANDRITZ’s order intake during the first quarter of 2025, reflecting strong market demand for premium lime kiln solutions in the Asian paper industry.

This project exemplifies how modern lime kiln technology continues to evolve, offering paper mills enhanced capabilities for efficient lime recovery, reduced environmental footprint, and optimized operational economics in their pulp production processes.
