1. Title
Clinker Reduction, Output Increase & Strength Enhancement for OPC Cement — ZS-OPC Cement Grinding Aid Industrial Trial
2. Customer Background
A cement company in Pingnan, Guangxi, operates a ∅4.2×13m combined grinding system producing P·II 42.5 (OPC) cement. With clinker content as high as 93.0%, clinker cost is the dominant component of production expenses. The customer sought to reduce clinker usage and increase mill output while maintaining cement quality.
3. Pain Points & Challenges
Excessively High Clinker Ratio: P·II 42.5 (OPC) cement clinker usage reached 93.0%, presenting significant cost reduction potential.
Mill Output Improvement Needed: Existing mill output was approximately 211 t/h, with room for capacity optimization.
Strength Must Be Maintained: Reducing clinker content required ensuring that strength continued to meet P·II 42.5 (OPC) standard requirements.
4. Solution
In December 2024, Shengchuan's technical team conducted a ZS-OPC Cement Grinding Aid industrial trial on the customer's ∅4.2×13m combined grinding system. Designed for high-clinker OPC cement systems, this product's core functions are optimizing particle size distribution, improving grinding efficiency, and activating late-stage clinker strength.
Trial Period: December 2–9, 2024
Grinding Aid Model: ZS-OPC Cement Grinding Aid
Dosage: 500g/t (0.05%)
Mix Proportion Adjustment: Clinker reduced from 93.0% to 90.0%, SCM increased from 2.0% to 5.0%
Trial Method: Blank comparison followed by 8-day continuous tracking with daily records of output, Blaine, and fineness.

6. Case Summary
After adopting ZS-OPC Cement Grinding Aid, P·II 42.5 (OPC) clinker usage was reduced from 93.0% to 90.0% (↓3 percentage points), mill output increased from 211 t/h to 241 t/h (↑14.2%), 7-day strength improved by 2 MPa, and power consumption decreased by 3 kWh/t. With standard consistency unchanged, the product achieved the triple objectives of clinker reduction, output increase with energy savings, and strength enhancement. The 8-day continuous production data demonstrates excellent industrial applicability.
7. Application Recommendations
Suitable Conditions: P·II or P·O high-grade cement production lines with clinker usage ≥80%, seeking clinker reduction alongside output and strength improvement.
Recommended Dosage: 500g/t.
Expected Results: Clinker usage reduction of 3–5 percentage points; output increase of 10%–15%; late-stage strength improvement of 2–3 MPa.
