Lime Kiln Technology

With decades of technological expertise and project experience, ACRE provides full-process design and EPC services in lime production, and delivers efficient, precise, and tailored sustainable solutions. 

Our lime production technology offers end-to-end engineering—from raw material washing and screening, through calcination, to product crushing, screening, briquetting, and passivation. We also design downstream processing lines for various calcium-based products. 

With over 70 years of experience in lime kiln R&D, engineering, and construction, we have supplied more than 90 rotary kilns and over 170 shaft kilns globally. Our kilns are engineered with a focus on energy efficiency, environmental sustainability, intelligent operation and optimal resource utilization. 

ACRE's JNH series rotary kilns are engineered for calcining diverse materials including limestone, dolomite, magnesia, high-alumina clinker, needle coke, and low-rank coal. Through continuous innovation in key components—preheaters, kilns, coolers, and burners—these kilns deliver industry-leading performance in energy efficiency, productivity, equipment service life, product quality, environment-friendliness, and intelligent operation, etc..
