A grinding mill is essential for producing ground calcium carbonate (GCC), a widely used industrial mineral in industries like plastics, paints, paper, rubber, and construction. Here’s an overview of grinding mills suitable for GCC production:
1. Types of Grinding Mills for Calcium Carbonate
Different mills offer varying particle sizes and production capacities:
# (1) Ball Mill
– Principle: Uses steel balls to crush and grind calcium carbonate.
– Particle Size: 45–150 µm (coarse to medium).
– Pros: Simple operation, cost-effective.
– Cons: Higher energy consumption, limited fineness.
# (2) Raymond Mill (Roller Mill)
– Principle: Uses rollers and rings to grind GCC.
– Particle Size: 38–180 µm (adjustable).
– Pros: Energy-efficient for medium-fine grinding.
– Cons: Not ideal for ultra-fine particles (<10 µm).
# (3) Vertical Roller Mill (VRM)
– Principle: Uses rollers on a rotating table.
– Particle Size: 10–100 µm.
– Pros: High efficiency, lower power consumption than ball mills.
– Cons: Higher initial investment.
# (4) Ultrafine Grinding Mill (HGM Series / Stirred Media Mill)
– Jet Mill, Alpine Air Classifier Mill, or Stirred Media Mill.
– Particle Size: 2–45 µm (ultra-fine GCC).
– Pros: Produces high-purity fine powders.
– Cons: Expensive maintenance.
# (5) Wet Grinding Mills (Attrition Mills & Bead Mills)
– Used for slurry-based GCC (45 µm), fine (10–45 µm), or ultra-fine (<10 µm)?
– Production Capacity – Small lab-scale vs. large industrial output?
– Energy Efficiency – VRM & ultrafine mills are more efficient than ball mills.
– Moisture Sensitivity – Wet grinding vs. dry grinding?
– Investment Budget – Ball mills are cheaper upfront; ultrafine mills cost more but yield finer products.
