Below is a detailed overview of its structure, capabilities, and applications.
 

---

‌1. Design and Engineering‌

‌1.1 Multi-Layered Roller System‌
The mill’s defining feature is its ‌32-roller configuration‌, strategically arranged in ‌four distinct layers‌ to optimize grinding efficiency:

1. ‌Upper Two Layers‌: Each layer contains ‌7 rollers‌ (14 rollers total), designed to pre-crush and disperse raw materials into smaller particles.
2. ‌Lower Two Layers‌: Each layer houses ‌9 rollers‌ (18 rollers total), applying intensified grinding pressure to refine particles to ultrafine sizes (as small as 5–10 microns).
   This layered approach ensures progressive material reduction, minimizing energy waste and maximizing output consistency.

‌1.2 Heavy-Duty Construction‌
Built for industrial durability, the mill features:

1. A ‌reinforced steel frame‌ capable of supporting its substantial weight and height (exact dimensions vary based on installation requirements).
2. ‌Wear-resistant components‌, including alloy rollers and grinding rings, engineered to withstand abrasive materials and prolonged operation.
3. A ‌vertical design‌ that enhances stability and reduces floor space requirements.

‌1.3 Power and Drive System‌
The mill operates on a high-torque power system, comprising:

1. ‌Main Grinding Unit‌: Powered by a ‌185 KW motor‌, driving the rotation of rollers and generating the force needed for material compression.
2. ‌Classifier‌: A ‌75 KW motor‌ powers an integrated dynamic air classifier, which precisely segregates particles by size (e.g., 200 mesh or 1000 mesh).
3. ‌Blower System‌: A ‌132 KW centrifugal blower‌ generates airflow to transport ground materials through the classification circuit, ensuring seamless integration of grinding and sorting processes.
   Total power consumption reaches ‌392 KW‌, reflecting its industrial-scale capabilities.

‌2. Performance and Production Capacity‌

‌2.1 Output Efficiency‌
The mill’s throughput varies depending on the target particle size:

1. ‌Coarse Grinding (200 mesh)‌: Achieves ‌12 tons per hour (t/h)‌, suitable for applications like cement additives, agricultural lime, or construction materials.
2. ‌Ultrafine Grinding (1000 mesh)‌: Delivers ‌6 t/h‌, ideal for high-value industries such as pharmaceuticals, premium coatings, and advanced ceramics.

‌2.2 Daily Production Potential‌

1. ‌Single-Shift Operation (8–12 hours)‌: Produces ‌80–100 tons/day‌, aligning with standard factory schedules.
2. ‌24/7 Continuous Operation‌: Output escalates to ‌150–200 tons/day‌, leveraging automation and minimal downtime for maintenance. This makes the mill ideal for mining operations, chemical plants, and large-scale material processing facilities.

‌3. Global Applications and Industry Use Cases‌

‌3.1 Regional Adoption‌

1. ‌Bangladesh‌: Widely used in ‌limestone processing‌ for agricultural soil conditioners and poultry feed additives, offering a 30% reduction in energy costs compared to traditional ball mills.
2. ‌South Korea‌: Employed in ‌advanced materials manufacturing‌, grinding silica and zirconia for semiconductor and display panel production, meeting stringent industrial quality standards.
3. ‌Ethiopia‌: Critical for infrastructure projects, processing volcanic rock into pozzolanic cement for dam and road construction.

‌3.2 Sector-Specific Applications‌

1. ‌Construction‌: Transforms marble and granite waste into fine fillers for composite materials.
2. ‌Chemicals‌: Produces ultrafine calcium carbonate (d97 < 10μm) for use in PVC, rubber, and paint formulations.
3. ‌Agriculture‌: Pulverizes phosphate rock into soluble fertilizers for high-demand agricultural regions.

‌4. Key Advantages‌

‌4.1 Energy Efficiency‌
The multi-layered roller system distributes grinding pressure evenly, reducing energy consumption by ‌15–20%‌ compared to conventional Raymond mills.
‌4.2 Precision and Flexibility‌

1. Adjustable roller pressure, classifier speed, and airflow allow customization for materials ranging from soft talc to hard quartz.
2. Optional upgrades include IoT-enabled monitoring systems, wear-resistant coatings, and dust control modules.

‌4.3 Economic Benefits‌

1. ‌High ROI‌: A cement plant in Ethiopia reported an ‌18-month payback period‌ due to increased output and reduced downtime.
2. ‌Labor Optimization‌: Automated controls minimize manual intervention, addressing labor shortages in high-demand regions.

‌5. Maintenance and Considerations‌

‌5.1 Operational Challenges‌

1. ‌Initial Investment‌: High upfront costs (≈500,000–500,000–800,000) may be prohibitive for small-scale operators.
2. ‌Component Wear‌: Rollers and grinding rings require replacement every ‌1,500–2,000 hours‌ under heavy use, necessitating a reliable spare parts supply chain.
3. ‌Technical Expertise‌: Optimal performance demands trained personnel for calibration and troubleshooting, underscoring the need for manufacturer-supported training programs.

‌5.2 Sustainability Features‌

1. The mill’s energy-efficient design aligns with global sustainability goals, reducing carbon footprints in mineral processing.
2. Future upgrades may include hybrid energy systems (e.g., solar-powered blowers) to further enhance eco-friendliness.
