1. Title
Coal Saving and Consumption Reduction Solution for Cement Clinker Calcination — ZS-Raw Material Grinding Aid Industrial Trial
2. Customer Background
A cement company in Hubei, China, operates one ATOX50 vertical roller mill and one φ5.0×74m rotary kiln. As a large new dry-process cement production line, raw meal grinding and clinker calcination are the core energy consumption stages. The customer sought to reduce coal consumption without affecting clinker quality.
3. Pain Points & Challenges
-
High coal consumption: Blank period standard coal consumption per ton of clinker was 96.44 kg/t, with room for reduction.
-
Occasional raw meal mill system faults: Frequent raw meal grinding system faults during the trial affected data completeness.
-
Kiln system coal saving is key: Even with raw meal mill data fluctuation, kiln system coal saving effect was the core validation target.
4. Solution
In November 2025, Shengchuan's technical team conducted a ZS-Raw Material Grinding Aid industrial validation on the customer's ATOX50 VRM and φ5.0×74m rotary kiln. The product reduces plant energy consumption from both electricity and coal saving, with a dosage of only 0.05%.

6. Case Summary
After using ZS-Raw Material Grinding Aid, standard coal consumption per ton of clinker decreased from 96.44 kg/t to 92.43 kg/t, a reduction of 4.01 kg/t (4.2%). Clinker daily output increased from 6,025 t to 6,290 t. During the trial, frequent raw meal grinding system faults affected raw meal mill data completeness, but the kiln system coal saving effect was clear. This trial provides valuable industrial reference for raw material grinding aid application in coal saving on large new dry-process production lines.
7. Application Recommendations
-
Suitable conditions: New dry-process rotary kiln production lines with high coal consumption, seeking to reduce kiln system coal consumption through raw meal optimization.
-
Recommended dosage: 500–800g/t
-
Expected results: Standard coal consumption per ton of clinker reduction of 3–6 kg/t.
