High-Efficiency Gypsum Milling Equipment for Cement Production and Plasterboard Manufacturing

High-Efficiency Gypsum Milling Equipment for Cement Production and Plasterboard Manufacturing

Introduction

Gypsum milling is a critical process in both cement production and plasterboard manufacturing, requiring precision equipment capable of delivering consistent particle size distribution while maintaining energy efficiency. Modern industrial demands call for milling systems that combine high throughput with low operational costs and minimal environmental impact.

Comparative Performance of Gypsum Milling Technologies
Technology Energy Consumption (kWh/t) Output Range (μm) Typical Capacity (t/h)
Ball Mill 35-50 45-250 5-40
Raymond Mill 25-40 30-325 3-25
SCM Ultrafine Mill 18-28 5-45 0.5-25
Industry Challenges

The gypsum processing industry faces three primary technical challenges:

  1. Particle size control – Plasterboard manufacturing requires D90 ≤ 150μm while cement retarder needs 45-200μm
  2. Moisture sensitivity – Gypsum’s hydroscopic nature demands closed-circuit systems with dehumidification
  3. Wear resistance – Gypsum’s medium hardness (Mohs 2) still causes significant abrasion on grinding components

Conclusion

Modern gypsum processing demands milling solutions that deliver precision, efficiency, and reliability. Our SCM Ultrafine Mill series, with its unique combination of German classifying technology and robust mechanical design, has proven capable of meeting these challenges across diverse applications from construction materials to medical-grade products.

For operations requiring coarser grinding in cement production, our MTW Series Trapezium Mill offers exceptional value with its patented curved duct design reducing airflow resistance by 15-20% compared to conventional mills. Both product lines feature our proprietary wear-resistant alloys extending maintenance intervals by 3-5x in typical gypsum service.
