Technical Specifications of SCM Series Ultrafine Mill

The SCM Series Ultrafine Mill is engineered to meet the rigorous demands of modern mineral processing, particularly for materials like gypsum. Its advanced design ensures high fineness, energy efficiency, and adaptability to diverse production scales. Below are the key parameters that make it ideal for gypsum powder manufacturing:

Input and Output Specifications

• Input Size: 0–20 mm, accommodating raw gypsum chunks directly from primary crushers.
• Output Size: Adjustable between 325–2500 mesh (5–47 μm), enabling customization for applications ranging from construction-grade plaster to high-purity medical or food additives.
• Production Capacity: Scalable from 500 kg/h (SCM800 model) to 25,000 kg/h (SCM1680 model), catering to both small-scale plants and large industrial facilities.

Core Components and Power Configuration

• Main Motor: Ranges from 75 kW (SCM800) to 315 kW (SCM1680), ensuring robust performance for continuous operation.
• Analytical Engine and Blower: Integrated frequency control systems optimize airflow and particle classification, achieving consistent fineness while reducing energy consumption.
• Auxiliary Systems: Pulse dust collectors (e.g., LDMC400×2) and screw conveyors ensure a closed-loop, pollution-free process, aligning with India’s environmental regulations.

Innovative Features

• Multi-Layer Grinding Rings: Enhances grinding efficiency by increasing particle collision frequency, reducing wear on components.
• Automated Control Systems: PLC-based interfaces allow real-time monitoring of parameters like temperature, pressure, and fineness, minimizing human intervention.
• Modular Design: Facilitates easy maintenance and upgrades, critical for minimizing downtime in high-volume production environments.

Role of SCM Mills in Gypsum Powder Production

Gypsum powder production involves multiple stages—crushing, calcination, grinding, and packaging—where the SCM Ultrafine Mill excels in the grinding phase.

Crushing and Pre-Processing

Raw gypsum lumps are first reduced to ≤20 mm fragments using jaw or hammer crushers. The SCM mill’s integrated vibrating feeder ensures uniform material flow into the grinding chamber, eliminating bottlenecks.

Precision Grinding

The mill’s grinding rollers and rings exert centrifugal force to pulverize gypsum into ultrafine particles. For example, the SCM1000 model achieves a fineness of 2500 mesh (D97 ≤5 μm), meeting the stringent requirements of specialty gypsum products like medical-grade plaster or fire-resistant coatings.

Calcination Integration

Post-grinding, gypsum powder is calcined in rotary kilns or boiling furnaces. The SCM mill’s compatibility with downstream calcination systems ensures seamless thermal processing, enhancing product consistency.

Advantages of SCM Mills in the Indian Market

India’s gypsum industry, valued at over $1.5 billion, demands equipment that balances cost, efficiency, and compliance. The SCM Series Ultrafine Mill addresses these needs through:

• Energy Efficiency: Reduces power consumption by 30–40% compared to traditional Raymond mills.
• Adaptability: Processes natural gypsum, phospho-gypsum, and recycled gypsum with equal efficacy.
• Environmental Compliance: Advanced dust collectors and noise reduction technologies align with India’s National Clean Air Program.

Case Study: SCM Mills in Indian Gypsum Plants

A leading cement manufacturer in Gujarat adopted the SCM1250 model to process 300,000 tons/year of gypsum powder. Key outcomes included:

• 50% reduction in energy costs through optimized grinding.
• Zero effluent discharge via closed-loop water cooling systems.
• 20% regional market capture with high-strength gypsum boards.

Future Trends and Opportunities

With India’s construction sector projected to grow at 7–8% annually, innovations like AI-driven predictive maintenance and Industry 4.0 integration will further elevate productivity. Government initiatives like the Production-Linked Incentive (PLI) scheme will incentivize adoption of advanced milling technologies.

Conclusion

The SCM Series Ultrafine Mill stands as a cornerstone of India’s gypsum powder industry, offering unmatched precision, scalability, and sustainability. By enabling high-quality production while adhering to environmental goals, it empowers manufacturers to thrive in a competitive market.
