Cement Grinding Plant Solutions | Precision, Efficiency & Sustainability
✅Strategic Role in Cement Production
The clinker grinding plant serves as the backbone of modern cement manufacturing, transforming hardened clinker nodules into finely tuned cement powder. By integrating precisely measured additives with clinker and applying advanced grinding technologies, we ensure final products meet exacting physical/chemical specifications for superior performance
✅Next-Gen Pre-Grinding Technology
The latest generation of cement grinding units has incorporated pre-grinding technology, which brings multiple advantages. Firstly, it effectively diminishes the particle size of the materials being fed into the grinding system. Secondly, it induces cracks and flaws within the particles themselves. These two effects work in tandem to significantly boost the production capacity of the cement mill. Moreover, the energy consumption during the grinding process is notably reduced, enhancing the overall efficiency and sustainability of the cement production operation.
✅Core Equipment Ecosystem
• Intelligent Grinding Mills: Ball Mills & Vertical Roller Mills (VRM) optimized for material characteristics
• Precision Separation: High-efficiency separators with 3-45μm particle size control
• Smart Material Handling: Automated feeding/conveying systems ensuring ±0.5% batching accuracy
• Eco-Friendly Operations: Pulse-jet bag filters achieving <10mg/Nm³ dust emissions
✅Competitive Advantages
1. High Efficiency
Cement grinding plant has high automation level, the operating process will adopt DCS central control system for adjustment, control and alarm in master control room, then the whole plant have less operator and also increase the working efficiency. The batching system have been adopt automatic quantitative feeding and measuring device, which have increase the material batching accuracy and also stablilizing the production’s quality.
2. Energy Efficiency
Adopting tube mill or vertical roller mill to producing qualify cement according to the raw material’s condition of clients. Producing system have adopt closed circuit to reduce the energy consumption of cement grinding. The single line scale can be from 15tpd to 1500tpd, which have been covered the cement factory’s different manufacture demand.
3. Environmental protection
Adoption of High efficiency air classifier and pulse type bag filter have created the circumstance for energy saving and energy consumption reduction.
4. High degree of automation
There is no manual operation in the process of mill running, which realizes the automatic control with long-term, stable, effective, makes milling process more stable, realizes fine work of production.

1.Batching
The shipping clinker is discharged into the dock crane and then transported to the clinker warehouse. After unloading at the bottom of the tent warehouse, it is transported to the clinker batching warehouse. Gypsum and slag are transferred from the loader to the crusher for crushing and then hoisted into gypsum and slag storehouse respectively.
2. Weighing, mixing and feeding cake
After battering the bottom of the warehouse, it will be sent to the stable flow weighing bin of the cement mill by the belt conveyor, and an iron remover will be arranged on the conveyor. The materials are mixed and stabilized in the steady flow weighing bin, and then fed into the cement roller press uniformly and continuously in the form of a material column. After the material passes through the high pressure, the physical structure is destroyed, forms the material cake and it will be raised by the hoist feeding classifier.
3. Grading
The classifier breaks the cake and grades it, and then separates the fine powder less than 6mm from the coarse powder more than 6mm. The coarse powder is returned to the stable flow weighing bin of the cement roller press, and then extricated again, and the fine powder is fed into the cement mill. After the fly ash is measured by the reamer scale, it goes through the chute into the hoist and feeds directly into the cement ball mill through the chute and the feeding chute.
4. Grinding
After cement ball mill grinding, materials enter into the powder separator, the fine powder is sent to the cement silo by the air transmission chute and the elevator, the coarse powder back to the cement mill to continue grinding. One part of the outgoing cement is controlled by the bottom unloader of the fluidized warehouse, and then through the air conveying chute and the elevator, sent to the packaging machine room for delivery, while the other part is sent to the bulk carrier for delivery by the air conveying chute.
