1. Title
Cement Rotary Kiln Coal Saving & Consumption Reduction — ZS-Coal Saving Agent Industrial Validation
2. Customer Background
A cement company in Guizhou operates two φ5.0×74m rotary kilns. The Guizhou region has abundant but variable-quality coal resources. The customer sought to reduce coal consumption and control fuel costs in the clinker calcination process through the addition of a coal saving agent.
3. Pain Points & Challenges
High Coal Cost Proportion: Coal consumption for clinker calcination is one of the core cost components in cement production.
Saving Effect Requires Verification: Industrial validation must cover blank, transition, and trial periods for complete comparison to ensure data reliability.
Kiln Stability: The addition of a coal saving agent must ensure stable kiln system operation without affecting clinker quality.
4. Solution
In November 2023, Shengchuan's technical team conducted a ZS-Coal Saving Agent industrial validation on the customer's φ5.0×74m rotary kilns. This product enhances coal combustion efficiency through combustion promotion, catalysis, and sulfur fixation mechanisms.
Coal Saving Agent Model: ZS-Coal Saving Agent
Recommended Dosage: 700g/t (0.07%)
Validation Period: 2-day blank period (Nov 6–7) + 2-day transition (Nov 8–9) + 2-day trial (Nov 10–11)

6. Case Summary
After applying ZS-Coal Saving Agent on the φ5.0×74m rotary kiln, standard coal consumption per ton of clinker decreased from 91.94 kg/t to 89.75 kg/t, a reduction of 2.19 kg/t (2.4%). After accounting for the coal saving agent cost, net clinker cost decreased by 2.24 RMB/t. This trial provides industrial reference for coal saving agent application on large rotary kilns.
7. Application Recommendations
Suitable Conditions: New dry-process rotary kiln production lines with high coal consumption, seeking systematic fuel cost reduction.
Recommended Dosage: 700g/t.
Expected Results: Standard coal consumption reduction of 2–3 kg/t clinker.
