Industry knowledge

As the final step in the cement manufacturing process, cement grinding plants undertake the crucial mission of transforming clinker and admixtures into finished cement. Jiangsu Haijian Co., Ltd. is a professional cement grinding plant manufacturer and company. We provide specialized cement production equipment, industrial solid waste incineration equipment, and specialized equipment for mining and metallurgy applications. Through refined grinding processes and scientifically controlled mix ratios, cement grinding plants produce cement products that meet various performance standards, directly impacting the quality and performance of cement.

The cement grinding process begins with raw material pretreatment. Clinker is pre-crushed to a particle size of ≤25mm in a hammer crusher before being precisely mixed with gypsum (3-5%), slag (up to 30%), fly ash, and other mixed materials in precise proportions before entering the batching system. Modern grinding plants primarily utilize two main grinding processes:

Ball mill system: A traditional closed-circuit grinding system equipped with a high-efficiency classifier (such as O-Sepa), with a circulating load controlled at 150-250%.
Roller press combined grinding system: Combining a roller press (pressure ≥ 200 MPa) with a ball mill, it offers excellent energy savings.

During the grinding process, the material undergoes multi-stage crushing and grinding, ultimately achieving a surface area of ​​3000-4000 cm²/g. The dynamic classifier precisely controls the fineness of the finished product by adjusting the rotor speed (adjustable range: 800-1500 rpm), maintaining a 45μm sieve residue of 12-16%. Particle shaping technology improves cement particle morphology by optimizing the grinding media gradation and grinding trajectory, increasing the circularity coefficient by 15-20%.

Key points for ensuring stable equipment operation:
Grinding mill liner: Measure wear monthly; replace if remaining thickness is less than 50%
Grinding media: Regularly replenish balls to maintain stable gradation
Powder separator rotor: Quarterly inspect blade wear
Lubrication system: Online oil quality monitoring, contamination level NAS ≤ 8
