The calcite grinding mill production line is designed to process raw calcite ore into fine powders (80-2500 mesh) for industrial applications like plastics, paints, and construction materials. Key equipment includes jaw crushers, bucket elevators, vibrating feeders, Raymond mills/vertical roller mills, and pulse dust collectors.
1. Jaw Crusher (Primary Crushing)
– Feed size: ≤1020mm
– Capacity: 50-800t/h
– Motor power: 55-400kW
2. Raymond Mill (Fine Grinding)
– Output fineness: 80-325 mesh
– Capacity: 1-20t/h
– Power consumption: ≤83kWh/t
3. Vertical Roller Mill (High-Efficiency Grinding)
– Output fineness: 200-2500 mesh
– Capacity: 5-100t/h
– Power consumption: ≤50kWh/t
1. Crushing: Calcite ore is crushed to ≤30mm by a jaw crusher.
2. Grinding: The crushed material is ground into powder via Raymond mill or vertical roller mill.
3. Classification: A classifier separates fine particles (meeting specs) from coarse ones (returned for regrinding).
4. Packaging: Finished powder is collected by a cyclone and packed automatically.
Q1: What’s the energy consumption of a calcite grinding line?
A1: Typically 40-80kWh/t, depending on fineness and equipment selection.
Q2: How to maintain grinding rollers?
A2: Lubricate bearings every 500 hours; replace wear parts after 800-1200 hours.
A Vietnam client installed a 15t/h calcite grinding line with our vertical roller mill (HLM2400). The output reached 2500 mesh with energy savings of 30% compared to traditional ball mills. Equipment ran stably for over 8,000 hours without major maintenance.
