An Indian customer, a well-known manufacturer of calcium carbonate powder, planned to upgrade its production line to achieve finer particle size, stable quality, and high coating efficiency. After technical discussions and material testing, the customer selected EPIC POWDER to supply a complete system — including a Ball Mill & Air Classifier Production Line and a Pin Mill Surface Coating System.
The goal was to produce high-quality modified calcium carbonate powder for use in plastics and coatings.
Equipment Configuration
Ball Mill & Air Classifier Production Line
The ball mill provides efficient fine grinding with a stable and uniform product size.
The air classifier precisely controls the final powder fineness, with adjustable particle size (D97 = 5–25 μm).
The system adopts a closed-loop operation, ensuring low energy consumption and dust-free production.
Pin Mill Surface Coating System
Used to modify the surface of the fine powder with stearic acid or other agents.
Features uniform coating, high efficiency (≥98%), and continuous operation.
Enhances powder hydrophobicity and dispersion in plastic or rubber matrices.
Materials:
Calcium Carbonate
Granularity:
D97: 10μm
Output:
