How LIMING Machinery delivered a reliable 800 TPH cement production line for Shanxi's challenging climate.
A major cement producer in Shanxi Province required a high-throughput cement production line to replace aging capacity and serve the region's growing construction market. The project was located in an area with cold winters and significant seasonal temperature variations, requiring specific engineering adaptations for reliable year-round operation. LIMING Machinery was contracted to supply all core process equipment and provide technical supervision for installation and commissioning.
The 800 TPH line is one of the larger throughput installations in the region, designed to achieve low production costs through economies of scale while delivering consistent product quality across all seasons.
The production line utilizes dry-process technology with an efficient pyroprocessing system. Raw material preparation features high-capacity crushing and grinding equipment, while the clinker burning section employs a modern rotary kiln with cyclone preheater and grate cooler for maximum thermal efficiency. Cement grinding is achieved through a large-capacity cement mill system with high-efficiency classification, producing consistent cement quality at the rated 800 TPH throughput.
For Shanxi's cold winters, the plant incorporates heated raw material storage areas, insulated process piping, and winterized utility systems to ensure uninterrupted operation even during extreme cold weather conditions. The control system provides real-time monitoring and automated adjustment of process parameters to maintain product quality throughout seasonal variations.
Shanxi's continental climate, with winter temperatures routinely falling below -15°C, required specific engineering measures. Key adaptations include: insulated and heated raw material storage to prevent freezing and blockages; heat tracing on critical process and utility piping; enclosed and heated conveyor galleries; cold-weather lubricants for all rotating equipment; and a winter startup procedure integrated into the plant's DCS control logic. These measures ensure the plant maintains full production capacity year-round without winter downtime.

Key Achievements
What makes this Shanxi cement production line a notable project.
At 800 TPH cement production capacity, this line is one of the largest-throughput installations in the Shanxi region, achieving exceptional production economics through scale.
Comprehensive winterization including heated storage, insulated piping, heat tracing, and cold-weather startup procedures ensures year-round operation in sub-zero temperatures.
Modern cyclone preheater with efficient heat recovery delivers low specific fuel consumption compared to older wet-process or semi-dry technologies.
Closed-circuit cement grinding with high-efficiency separator and automated process control maintains tight quality specifications on cement fineness and strength.
DCS control system incorporates winter-mode operating logic that automatically adjusts process parameters, startup sequences, and equipment protection for cold-weather conditions.
Grate cooler with maximum heat recovery to the kiln and preheater, combined with efficient grinding technology, achieves competitive specific energy consumption figures.
