Solution Capability
Liming provides comprehensive clinker grinding line services including:
Process design and engineering
Equipment manufacturing and supply
Installation and commissioning support
Production optimization
Spare parts and lifecycle service
With proven project experience and integrated solution capability, the company helps cement producers achieve efficient, stable, and sustainable grinding operations.

A clinker grinding line is the final stage of cement manufacturing, where cement clinker is ground together with gypsum and optional additives to produce finished cement products with specified fineness and performance characteristics. This system plays a decisive role in cement quality, energy consumption, and plant operating efficiency.

With extensive experience in cement equipment engineering, Liming provides complete clinker grinding line solutions including equipment supply, system integration, installation guidance, and technical optimization. The solutions are suitable for both standalone grinding stations and integrated cement production plants.

Advantage

High Grinding Efficiency
Optimized grinding and classification circuits improve powder selection efficiency and increase system throughput.

Energy Saving Operation
Advanced grinding technologies and process integration reduce power consumption per ton of cement.

Stable Product Quality
Precise batching and closed-circuit grinding ensure uniform particle size distribution and consistent cement performance.

Flexible Configuration
The grinding line can be configured for different cement types and production capacities, supporting plant expansion and product diversification.

Environmental Compliance
Efficient dust collection and enclosed material handling minimize emissions and improve working conditions.

Working Principle

1. Material Storage and Batching
Clinker, gypsum, and supplementary materials are stored in dedicated silos. Each material is extracted through speed-controlled feeders and weighed by belt scales to achieve accurate proportioning before entering the grinding system.

2. Pre-Grinding and Classification
The mixed materials are conveyed to the grinding system, where pre-grinding devices and classifiers separate coarse and fine fractions. Coarse particles are returned for further grinding, while qualified materials proceed to the next stage.

3. Grinding System
The core grinding unit can adopt different configurations according to project scale and energy targets, such as:
Roller press + ball mill combined system
Vertical roller mill grinding system
Ball mill closed-circuit system
During grinding, impact, compression, and shear forces reduce particle size to the required cement fineness.

4. Separation and Dust Collection
Ground material is lifted to a high-efficiency separator. Qualified fine powder is collected as finished cement, while coarse particles are recycled. Exhaust air is treated by bag filters to ensure low emission levels and environmentally compliant operation.

5. Cement Storage and Dispatch
Finished cement is transported to storage silos and subsequently delivered in bulk or packed form according to customer requirements.
