Complete Cement Grinding Plant Solutions – Lower Investment, Faster Payback, Guaranteed Output Turnkey cement grinding station solutions from 100,000 to 2,000,000 TPY. Our integrated closed-circuit ball mill systems with high-efficiency separators deliver consistent cement quality, energy consumption below 30 kW·h/t, and project delivery in 12-18 months. Whether building a new grinding plant or upgrading an existing facility, we provide full EPC services from design to commissioning — trusted by cement producers in over 50 countries.
Our cement grinding station is a complete, integrated production facility engineered to produce high-quality cement from clinker, gypsum, and supplementary cementitious materials. We deliver the entire plant as a single-source EPC project.

From Raw Materials to Bagged Cement: How Your Grinding Station Works
Raw Material Intake & Storage – Clinker, gypsum, and additives are received by truck or rail and stored in dedicated hoppers or covered storage. Moist slag and limestone are stockpiled under pre-blending beds for compositional consistency.
Precise Weighing & Feeding – Clinker and all additives are extracted by belt weighers with ±0.5% accuracy and conveyed to the mill feed chute. Gypsum dosage is precisely controlled to meet SO₃ target in the final cement.
Grinding Circuit (Closed-Circuit) – The clinker-gypsum-additive mix is fed into the ball mill. After grinding, the material is elevated to the dynamic separator. Fines (finished cement) are sent to silos; coarse particles return to the mill. For larger plants, a roller press pre-grinds the feed before the ball mill, reducing total power by 25-35%.
Cement Cooling & Storage – Finished cement is cooled in a cement cooler to <80°C and conveyed to multi-compartment silos by air slides or bucket elevators. Silos are sized for 7-15 days of production buffer.
Packing & Dispatch – Cement is extracted from silos and routed to a rotary packer (for 50kg bags) and/or bulk loading spouts. A weighbridge and automated loading system enable efficient truck dispatch.
