The Comprehensive Guide to Gypsum Powder Production Line in Algeria

Industry Background

The global construction sector heavily relies on processed mineral materials, with gypsum powder being a key component for cement, drywall, and soil conditioning. Algeria, rich in natural gypsum reserves, has seen growing demand for high-quality gypsum powder to support infrastructure and housing projects. As a result, efficient crushing and grinding production lines are critical to meet industry standards while optimizing cost and energy consumption.

Core Components of a Gypsum Powder Production Line

1. Primary Crushing
– Jaw Crusher: Breaks large gypsum rocks (<800mm) into smaller pieces (~100mm).
– Hammer Crusher: Optional for softer gypsum, reducing particle size further.

2. Grinding & Calcination
– Raymond Mill/Vertical Roller Mill: Grinds crushed gypsum into fine powder (80–200 mesh).
– Rotary Kiln/Flash Calciner: Heats gypsum to remove crystalline water (calcination at 150–180°C for stucco production).

3. Screening & Packaging
– Vibrating Screen: Separates oversized particles for re-grinding.
– Automatic Packing System: Ensures precision for bulk or bagged products.
