A calcium oxide (quicklime) grinding production line transforms limestone or shells (containing CaCO₃) into fine powder through calcination (heated above 825°C to release CO₂). Here’s a breakdown of the essential equipment:
1. Crushing Equipment
Jaw Crusher: Primary crushing of bulk calcium oxide. Its two jaw plates apply compressive force, offering high reduction ratios, simple structure, and easy maintenance.
Impact Crusher/Hammer Crusher: Secondary crushing for uniform particle size. Impact crushers use high-speed plate hammer strikes, while hammer crushers rely on rotating hammers—ideal for medium-hardness materials.
2. Grinding Equipment
Raymond Mill: Produces medium-fine calcium oxide powder (80–325 mesh). Rollers grind materials against a ring, paired with an analyzer for adjustable fineness. Features energy efficiency and compact design.
Vertical Roller Mill: Ideal for large-scale production with integrated grinding, drying, and classification. Higher efficiency and lower energy consumption than Raymond mills.
Ultrafine Grinding Mill: Achieves fineness beyond 325 mesh (even to microns) with advanced classification and grinding technology.
3. Classification Equipment
Air Classifier: Separates fine powder from coarse particles using airflow, ensuring consistent product fineness.
4. Conveying Equipment
Bucket Elevator: Vertically transports raw materials or powder via chain/belt-driven buckets. Handles heavy loads with stability.
Screw Conveyor: Moves powder horizontally/inclined with rotating helical blades. Offers airtight sealing and simplicity.
Pneumatic Conveying System: Transfers powder over long distances through enclosed pipes using airflow—efficient, low-energy, and dust-free.
5. Storage Equipment
Raw Material Silo: Ensures continuous supply, equipped with level sensors and dust collectors.
Finished Product Silo: Stores ground powder with moisture/dust-proof designs for quality preservation.
Pulse Jet Dust Collector: Captures airborne dust with high-efficiency filter bags, cleaned by pulsed air jets.
6. Dust Collection Equipment
Bag Filter: Ensures emissions compliance by trapping dust on fabric filters while releasing clean air.
7. Control System
PLC Automation: Manages equipment operation, parameter adjustments, fault alerts, and remote monitoring for optimized productivity.
