1. Key Considerations for Barite/Fluorite Grinding Plant Investment
# A. Raw Material & Market Demand
– Barite (BaSO₄): Used in oil/gas drilling (80% of demand), chemicals, paints, and medical applications.
– Fluorite (CaF₂): Used in metallurgy, glass, ceramics, and hydrofluoric acid production.
– Ensure stable supply sources and assess local/export market demand.
# B. Production Capacity
– Small-scale: 1–5 tons/hour
– Medium-scale: 5–20 tons/hour
– Large-scale: 20+ tons/hour
*(Higher capacity = higher upfront cost but lower per-unit operating cost.)*
# C. Grinding Mill Selection
– Raymond Roller Mill (Most common for barite/fluorite):
– Fineness: 80–325 mesh (adjustable up to 600 mesh with classifiers).
– Low energy consumption, easy maintenance.
– Suitable for small-to-medium projects.
– High-Pressure Grinding Roll (HPGR):
– Energy-efficient for harder ores.
– Higher initial cost but lower wear than ball mills.
– Ultrafine Vertical Roller Mill:
– For superfine powder (400–2500 mesh).
– Higher investment but better for high-value applications.
# D. Auxiliary Equipment
– Crusher (jaw/impact crusher for primary crushing).
– Bucket elevator/conveyor system.
– Dust collector (pulse jet bag filter recommended).
– Packing machine (for finished powder).
