Case Overview
| Item | Details |
|---|---|
| Customer / Location | A major non-metallic mineral processing enterprise in Bangladesh |
| Material | Ground Calcium Carbonate (GCC), commonly known as heavy calcium |
| Equipment Solution | Epic Powder Ball Mill and Classifier Production Line |
| Core Challenge | Meeting the growing demand from local coatings, plastics, and papermaking industries for high-fineness, high-output GCC powder |
| Target Performance | Output: stable 5 t/h; Product fineness: D50 ≤ 5 μm |
Market Background & Customer Needs
Bangladesh is one of the fastest-growing economies in South Asia.
Industries such as infrastructure, consumer goods manufacturing, and packaging have driven strong demand for high-quality filler materials.
Ground calcium carbonate is a foundational raw material widely used across these sectors.
The customer, a leading mineral processor in the region, faced several key challenges:
1. Increasing requirements for fineness and quality
Traditional grinding equipment struggled to consistently produce high-grade GCC with D50 at 5 μm or finer.
Such fineness is essential for high-gloss paints, high-strength plastic masterbatches, and premium paper products.
2. Output limitations
Market demand was rising rapidly.
The customer needed a production line capable of stable operation at 5 t/h.
3. Energy consumption and operational stability
They sought advanced equipment that could deliver high output and ultrafine products while reducing energy consumption and improving long-term reliability.
Solution: Epic Powder Ball Mill & Classifier Production Line
To meet the customer’s high-output and ultrafine requirements, Epic Powder deployed its high-performance Ball Mill + Classifier integrated production system.
Core Equipment Configuration
High-Efficiency Ball Mill
- Optimized length-to-diameter ratio
- Equipped with advanced grinding media
- Provides a high-energy, high-efficiency grinding environment
- Capable of reducing GCC to sub-micron levels
High-Precision Classifier
- Uses airflow vortex classification technology
- Accurately separates fine powder from coarse particles
- Fine powder enters the finished product silo
- Oversized particles are automatically returned to the ball mill for further grinding
- Forms a highly efficient closed-loop system
Process Advantages
Optimized Closed-Circuit Operation
The ball mill generates ultrafine particles, while the classifier ensures accurate separation and recirculation. This guarantees product fineness that is precise and stable within the target range.
High-Output Design
The system was engineered for the customer’s required 5 t/h capacity. Large-scale equipment and process optimization ensure high efficiency during continuous operation.
Implementation Results
After installation, commissioning, and long-term operation, the production line delivered outstanding performance:
| Performance Indicator | Target | Actual Result | Assessment |
|---|---|---|---|
| Output | 5 t/h | Stable at 5.2 t/h | Exceeded expectations |
| D50 Fineness | ≤ 5 μm | 4.8 μm | Precisely controlled |
| Equipment Uptime | High | ≥ 98% continuous operation | Excellent stability |
| Energy Consumption | Optimized | ~15% lower than traditional systems | Significant economic benefit |
