The customer is a well-known chemical enterprise in India specializing in flame retardants, fillers, and specialty chemicals. Aluminum Trihydrate (ATH), as a high-performance, halogen-free, and environmentally friendly flame retardant and functional filler, is experiencing rapidly growing market demand. However, the customer’s existing Aluminum Trihydrate processing equipment showed clear limitations when facing high-quality production requirements:
Key Challenges
High Fineness Requirement:
The market increasingly demands finer ATH products. The customer needed to consistently achieve D50: 7–8 μm to meet performance standards for high-end plastics, cable compounds, and artificial stone.
Large Output With High Stability:
A stable production capacity of 10 t/h was required, along with a very narrow particle size distribution and excellent batch-to-batch consistency.
Equipment Contamination & Wear:
Traditional metal mills pose a risk of metal contamination when processing white powders. In addition, Aluminum Trihydrate (ATH), as a high-performance, halogen-free, and environmentally friendly flame retardant and functional filler, is experiencing rapidly growing market demand. has moderate hardness, causing significant equipment wear.
The customer urgently needed a system capable of combining high capacity, ultrafine particle size, zero contamination, and low wear in one integrated solution.
Solution: Epic Powder’s Ceramic-Lined Ball Mill + Air Classifier System
After comprehensive technical analysis and customized engineering, Epic Powder delivered a solution consisting of a ceramic-lined ball mill paired with a high-precision air classifier.
Equipment Configuration & Technical Highlights
1. Main Grinding System: Epic Powder Energy-Saving Ceramic-Lined Ball Mill
Core Advantages:
- Zero Contamination:
Designed for high-purity requirements, the ball mill uses high-purity ceramic liners and ceramic grinding media. This eliminates any risk of iron or heavy metal contamination during grinding, ensuring product purity and whiteness. - Energy Efficiency & High Output:
An optimized length-to-diameter ratio and advanced drive system guarantee high-efficiency energy transfer, achieving large-scale output of 10 t/h while reducing energy consumption per ton.
2.High-Precision Classification System: Epic Powder Air Classifier
Key Functions:
- Accurate Real-Time Separation:
The classifier outputs fine powder meeting D50: 7–8 μm, while returning coarse particles to the ball mill for closed-loop grinding. - Precise Control:
Equipped with advanced online particle size monitoring and frequency-controlled classifying wheel speed and airflow adjustment. This ensures a stable and narrow particle size distribution even under high-flow operating conditions.
The production line adopts a highly efficient closed-loop system, ensuring full utilization of raw materials and exceptional stability in final product fineness.
