A complete cement production line supplied by Liming Machinery is composed of multiple coordinated systems designed to ensure stable operation, high efficiency, and consistent product quality. The overall structure can be described as follows:

Mining System

Modern limestone mining adopts advanced drilling, blasting, and loading equipment to extract raw limestone efficiently. The mined material is controlled in size to meet downstream processing requirements while ensuring safety and productivity.

Raw Material Crushing System

Primary and secondary crushing equipment, including jaw crushers, hammer crushers, and impact crushers, reduce large limestone blocks into particles smaller than 70 mm, making them suitable for storage and grinding.

Raw Material Homogenization and Storage System

Crushed limestone, clay, and corrective materials are stored in pre-homogenization yards. Stackers and reclaimers automatically manage material stacking and reclaiming, ensuring a stable and uniform chemical composition.

Raw Material Proportioning System

Electronic belt weighers accurately measure each raw material according to the process formula, enabling precise batching and stable raw meal quality.

Raw Material Grinding System

The proportioned materials are ground in ball mills or vertical raw mills. These systems integrate drying, crushing, and grinding into a single process, improving energy efficiency and reducing operating costs.

Raw Meal Homogenization and Kiln Feeding System

After grinding, the raw meal is homogenized again in blending silos to further stabilize chemical composition before being fed into the kiln.

Preheating System

Multi-stage cyclone preheaters and precalciners preheat and partially decompose the raw meal, achieving up to 80% decomposition before kiln entry. This significantly improves thermal efficiency and lowers fuel consumption.

Clinker Calcination System

The rotary kiln is the core of the cement production line, where raw meal is calcined into clinker at temperatures above 1000 °C. Liming Machinery provides highly automated kiln systems that ensure stable operation, high output, and low energy consumption. Pulverized coal, prepared by vertical coal mills or air-swept coal mills, is used as fuel, with comprehensive monitoring and safety systems to prevent fire and explosion risks.

Cement Grinding and Blending System

Clinker is mixed with gypsum and other additives based on specific cement formulations, then ground using cement ball mills, roller presses, or high-efficiency classifiers to achieve the required fineness and performance.

Cement Storage and Dispatch System

Finished cement is stored in silos and subjected to strict quality inspection. According to customer needs, cement can be delivered in bulk or packed into bags for distribution.

This integrated system layout ensures efficient production, consistent cement quality, and reliable long-term operation for modern cement plants.
